ABSTRACT -- The Aaron Scott Site dinosaur quarry (Quarry) in the Morrison Formation of Utah offers a unique view of Late patterns of terrestrial diversity. The Quarry represents a rare perennial lacustrine environment of deposition, preserving a diverse population of large and small vertebrate and invertebrate fauna.

The null hypotheses state that patterns of diversity at the Quarry do not differ significantly from those found at ephemeral lacustrine sites elsewhere in the Morrison, and an even spread of terrestrial diversity across the Morrison Basin.

While evidence has revealed a similarity between the Quarry and ephemeral lacustrine sites, multivariate analysis reveals distinct patterns in terrestrial diversity of the Morrison Formation, most prominently, a division between wetland and dry land taxa, and between ornithischian and sauropod dominated environments. Unusual patterns found among several taxa pairs hint that two (or more) Morrison genera may be sexual dimorphs or organisms at different stages in their ontogeny. While the Quarry itself may not be wholly unique, the Morrison was far more complex than traditionally portrayed.

Introduction

The Aaron Scott Site Dinosaur Quarry (Quarry) is a major new Jurassic vertebrate locality in the Morrison Formation of Utah that provides a strong educational and outreach resource for undergraduate institutions in Ohio and Kentucky. Since its discovery in 2001, the

Quarry has gained importance in its and stratigraphic context, due in part to the richness and diversity of its taxa. The Quarry provides abundant and robust paleoecological, taphonomic, paleolimnologic, fluviodeltaic sedimentological, sequence stratigraphic, and paleoclimatic data on the Morrison Formation’s depositional setting. Given the unique depositional environment at the Quarry, it would be reasonable to suppose that fauna there was distinct from the rest of the Morrison. This paper tests that hypothesis, examining the Quarry’s faunal assemblage in the context of the Morrison Formation as a whole. In doing so, this paper also tests the long-held hypothesis that the ancient Morrison Basin was environmentally and ecologically homogenous.

A collaborative team of paleontologists and stratigraphers from Cincinnati Museum

Center, the University of Cincinnati, Marietta College, and Northern Kentucky University continues research at the Quarry that includes vertebrate excavation, preparation, and study of the , and stratigraphic, sedimentologic and geochemical studies of the enclosing package of sediments. The team consists of faculty with experience in paleontology and stratigraphy who lead a diverse group of undergraduates, graduate students and volunteers.

The Quarry is of significance in large part because the abundant accumulation of vertebrate fossils – particularly “microvertebrates” – provides insights about its depositional setting and faunal history within the Morrison Formation. Traditionally known as a river and

1 Esker1/26/2009 floodplain environment, the Morrison Formation is also widely known for its rich dinosaur accumulations (Turner and Peterson, 2004). Large dinosaur fossils in the Quarry include a variety of sauropod and isolated elements of Allosaurus, but this site also abounds in microvertebrates, including several sphenodontid .

Discoveries in the Quarry hint at the potential to produce Jurassic fossils, although to date, none has been found. Very little is known of Jurassic due to their rarity and the paucity of fossils in the Morrison Formation, but the high frequency of microvertebrates at this site is indicative of a significant potential to produce mammalian and associated fauna. In to fully understand the environment in which these lived and died, the enclosing strata are being analyzed, stratigraphically and geochemically.

Marietta College and Northern Kentucky University are undergraduate institutions that use the Quarry in their respective public outreach programs, making this site of great value for basic research and science education by involving undergraduate students in the research process

(field work, lab work, and presentation of the results).

Broader Scientific Impacts Ongoing work has demonstrated that the sediments enclosing the Quarry assemblage are the consequence of fluvio-deltaic processes resulting in infilling of a lake basin (Jeffery Bertog, and Bishop, 2005). The strata display sequence stratigraphic relationships caused by interactions between sediment supply and fluctuations in lake water volume. The fluctuations in water volume are interpreted to have resulted from severe drought conditions that would have driven animals to congregate around large, permanent lakes, thus resulting in the rich accumulation at the Quarry. These interpretations are possible because of the excellent exposure of the bone beds and the enclosing sediments that help put the deposit into a more profound depositional context.

The Morrison Formation is traditionally considered a meandering river floodplain environment (Turner and Peterson, 2004). This formation is known for its dinosaur population and is the most dinosaur-rich formation in the (Turner and Peterson, 1999). The

Quarry contains fragments of typical Jurassic – especially Diplodocus, ,

Stegosaurus and as well as Allosaurus – but among these typical, Morrison

Formation dinosaurs are numerous (but less well known) microvertebrates. The abundance of these microvertebrates is a strong indicator that the Quarry may also contain early mammal remains (Bertog, et al., 2005). While Jurassic mammals have been found in the Morrison

Formation, their numbers have been relatively few; thus very little is known about these animals.

Continued research at this locality may yet reveal important information about population size, diversity and development during this early period in mammalian history.

In order to understand the preservation of these microvertebrates and the environment where these animals lived, research at the Quarry includes sedimentologic and taphonomic analysis. Detailed stratigraphy is being measured and analyzed (Jeffery, Bertog, and Bishop,

2005) to delineate the Quarry within a broader context. On a finer scale, as fossils are excavated, they are mapped using traditional grid methods and a Nokia laser transit. The resulting distribution grid is used to create a 3-dimensional map of the Quarry. Bone orientation is also measured to discern preferred orientation that would be suggestive of reworking of the bones by current (Bertog et al., 2005). Bone orientation and distribution relative to the stratigraphic relationships of the enclosing strata, can provide insights into where and why they were preserved (Jeffery, Bertog, and Bishop, 2005; Bertog et al., 2005).

The factors responsible for the distribution and concentration of rich terrestrial vertebrate deposits are fundamentally tied to the biology of the organisms and to the climate and landscape of their environment. The death assemblage and the sediments supply proxy evidence for biology, climate, and landscape as recorded in the relationships between the taphonomy and the stratigraphic architecture of the accumulation. Distinctive fossil localities afford a well exposed view of stratal relationships of the bone beds and their enclosing sediments and thus contribute compelling and substantial evidence about their paleoecology, paleogeography, and paleoclimate. While skeletal relationships of fluvial bone bed accumulations have been well documented, lacustrine bone beds that display sequence stratigraphic relationships are rare or possibly, unrecognized. Thus, the Quarry offers a distinctively promising opportunity to study these relationships.

Background

Paleontology The site was discovered in 2001, within the lower portion of the Brushy Basin Member of the Upper Jurassic Morrison Formation and contains a rich assemblage of vertebrates and invertebrates (Jeffery, Bertog, and Bishop, 2004; Jeffery, Bertog, and Bishop, 2005; Bertog et al., 2005). The Quarry is located in Emery County, Utah, southeast of the town of Ferron.

The Morrison Formation crops out within the Western Interior region of the United States and Canada and extends south to central (Turner and Peterson, 2004). The exposures of east-central Utah lie within the Colorado Plateau region, where it generally consists of flat-lying beds of sedimentary rock including variegated siltstones, shales, and sandstones

(Craig, 1955). The Quarry is located on the western margin of the San Rafael Swell, a NE- trending broad, asymmetrical Laramide upwarp roughly 75 miles long and 30 miles wide with a steeply dipping eastern margin and a gently dipping western margin (Lawton et al., 1983, Stokes,

1986). The landscape at the Quarry consists of numerous cuestas, dipping westward on the order of 11 degrees. It is difficult to differentiate what proportion of the dip is depositional, but most is probably tectonic.

Hundreds of bones from the Quarry have been collected with preliminary identification of vertebrate taxa including fragments of a sauropod skull (possibly Barosaurus), articulated sauropod vertebrae and other bones from one or more individuals, bones of at least two

Allosaurus individuals (based on size classes of pedal phalanges, one individual is a very small specimen, less than 1 meter tall), numerous teeth – including a broken-off tooth penetrating a bone, numerous bones belonging to Stegosaurus, , , and small ornithopods

5 Esker1/26/2009

(possibly Dryosaurus), a large collection of as yet unidentified small bones and teeth, a partial skull and several lower jaws of sphenodontids.

The bones are in poor to good condition, black, and fragmentary to complete. The bone horizon consists of calcite-cemented, very light gray lithoclastic silty sandstone overlain by a medium gray, heavily bioturbated silty mudstone with abundant bivalves of the freshwater

Unio.

The Morrison Formation contains an extremely well known assemblage of Jurassic vertebrates that has been extensively studied since the late 1800’s (Foster, 2003). Recent individual articles and article collections provide prolific detail and summary of the sedimentology, stratigraphy, paleontology, and history of this vast dinosaur resource (Carpenter et al. 1998; Gillette, 1999; Foster, 2003; Turner and Peterson, 2004). Numerous studies focus on dinosaur assemblages within individual quarry localities (e.g., Bilbey, 1998; Richmond and

Morris, 1998; Gates, 2005) or summarize published quarry data from the rich Morrison literature

(Foster, 2003). Turner and Peterson, (2004) introduced a series of papers, each of which is a synthesis of the “state of the paleoecology of the Morrison” in terms of the sub-disciplines of sedimentology and paleontology.

Stratigraphy The Morrison Formation in east-central Utah has been subdivided into three members: the Tidwell, Salt Wash, and Brushy Basin. These units are described in great detail by numerous authors (Dodson et al., 1980; Peterson and Turner-Peterson, 1987) and in the research notes and references on the nearby Cleveland Lloyd Dinosaur Quarry (Bilbey, 1998; Gates, 2005). The

Tidwell Member contains mudstones, limestones, and evaporites that are interpreted as mudflat,

6 Esker1/26/2009 playa, and sabkha environments and is the transition from the marine and marginal marine sediments of the underlying Summerville Formation (Turner and Peterson, 2004). The Salt

Wash Member consists primarily of coarse fluvial sands and lake and floodplain mudstones

(Peterson and Turner-Peterson, 1987; Gates, 2005). The Brushy Basin Member near the Quarry consists of a lower gray lake unit that interfingers with the Salt Wash Member and an upper red, gray, and green banded unit (Figure 1).

Figure1:SimplifiedStratigraphyoftheMorrisonFormation–Source:Kowallisetal.1998.

At the Quarry, the apparent thickness of the interval between the Summerville Formation and the upper Brushy Basin Member of the Morrison (that is, the thickness of the lower Brushy

Basin Member) may be 30-50 m, but this estimate is problematic because the beds of the

Tidwell, Salt Wash, and lower Brushy Basin members are westward off-lapping wedges that crop out in a broad, north-south belt (Bertog and Jeffery, 2005). The lower Brushy Basin

Member consists primarily of gray mudstones with interbedded, thin limestone and discontinuous sands.

7 Esker1/26/2009

The upper Brushy Basin Member is up to 175 m thick and predominantly contains red, green, and gray mudstones giving it distinctive horizontal banding with minor discontinuous epsilon cross-bedded sand lenses. This unit has largely been interpreted as a meandering river and floodplain deposit (Gates, 2005). The distinctive red coloring of the upper unit is primarily due to the abundant paleosols contained therein (Demko et al., 2004). The Quarry lies in the upper portions of the gray mudstones of the lower Brushy Basin Member that is interpreted to have been laid down in a lacustrine depositional environment.

The Morrison ecosystem has been interpreted as a seasonally arid plain, dominated by meandering river systems and ephemeral lakes (Dodson et al., 1980; Parrish, Peterson, and

Turner,, 2004, Turner and Peterson, 2004; Gates, 2005). Turner and Fishman (1991) cite the presence of a large, alkaline, saline lake that covered a large portion of the Colorado Plateau, primarily east of the Four Corners area during late time. More recent interpretations cite evidence that the large lake may have been more of a wetland/lacustrine complex (Dunagan and Turner, 2004).

Lake sediments in the area of the Quarry are far to the west of the large lake cited by

Turner and Fishman. They lie directly above and interfinger with the middle Kimmeridgian Salt

Wash Member (Turner and Peterson, 2004). The lake sediments enclosing the Quarry lie within the depositional area of the Tidwell Member in east-central Utah, interpreted as a small

“embayment” in the Jurassic Epeiric Seaway during the early Kimmeridgian by Turner and

Peterson (2004). Once this early Kimmeridgian sea withdrew, the “embayment” could have become a lake basin that progressively freshened and filled during the middle Kimmeridgian.

Stratal geometries, cyclical stacking patterns and detailed taphonomic analysis of the

Quarry in the lower Brushy Basin Member of the Morrison Formation can be used to infer

8 Esker1/26/2009

sequence stratigraphic relationships and reveal that sediments were deposited during the

progressive fill of a large lake, accumulating within a prograding fluvio-deltaic lacustrine system

(Jeffery, Bertog, and Bishop, 2005; Bertog et al., 2006; Bertog et al., 2005). Sequence

stratigraphic relationships have been well documented in numerous studies dealing with aspects

of lacustrine and related strata in terms of petroleum source rock deposition and stratal

geometries of progressive lake basin fill (e.g., Keighley et al., 2003; Carroll and Bohacs, 2001;

Oviatt, McCoy, and Nash, 1994; Dam and Surlyk, 1992).

Observations from both stratigraphic and taphonomic analyses in this study support the

hypothesis that the deposit is within lake-margin sands, probably at a beach or distributary bar

and that variations in water volume within the lake caused the changes in base level (Jeffery,

Bertog, and Bishop, 2005). The variations in base level are responsible for the preservation of an

assemblage that is interpreted to have accumulated as the result of a brief lowering and

subsequent rise of lake level during the late stages of an overall fall in base level (late highstand),

but prior to the formation of the next distinct cycle boundary.

The brief lowering in base level is believed to have been the result of temporary drought

conditions that eliminated smaller watering holes. The presence of the perennial lake resulted in

a high rate of dinosaur and other vertebrate traffic at the margins of the largest regional body of

water1. This situation likely lasted for the duration of the drought. Such brief fallen

parasequences or drought-forced regression episodes are conducive to preservation of rich

assemblages because of the high traffic and the rapid submergence and burial at the end

of each drought. Evidence for this can be seen in the varying quality of preservation of fossils at

9 Esker1/26/2009 the site. Some presumably very durable fossils, including sauropod limb elements and centra show extreme wear – indicating that deposition near the beginning of the drought and significant subsequent sub-aerial exposure. Other extremely delicate microvertebrate fossils show exceptional preservation, and thus cannot have been exposed for any great length of time. More likely, they were deposited shortly before the lake level rose at the end of the drought.

Quarry History and Activity

The Marietta College team, currently led by Dr. David L. Jeffery, discovered the Aaron

Scott site and began excavating its contents in 2002, followed to date by seven field seasons

(2002 - 2008). Faculty and students from the University of Cincinnati, and faculty and students from Northern Kentucky University, led by Dr. Janet L. Bertog, joined the research team in

2006.

The field area is near Ferron, Utah and is primarily on federal and state land overseen by the US Bureau of Land Management and the State of Utah, respectively. Specimens were field mapped, excavated, and collected in plaster jackets under permit from federal and state agencies, then transported to Marietta College and Cincinnati Museum Center for preparation.

Excavation Techniques Standard vertebrate paleontology excavation and preservation techniques were used in the Quarry. The pit itself takes up much of the top and north face of a low hill near the base of a large promontory. The Quarry is located at approximately 39° 01' N, 110° 29' W, in the Horn

Silver Gulch 7.5’ quadrangle of Emery County, Utah. (Figures 2 & 3).

11 Esker1/26/2009

Figure3:ViewoftheAaronScottSite

12 Esker1/26/2009

Approximately two feet of overburden near the top of the hill was removed with shovels, buckets, and occasionally, a small jackhammer. The layer directly above the bone-bearing horizon was composed of a dense clam-bed, 25-30 cm thick containing bivalves similar to the genus Unio (Evanoff, Good, and Hanley, 1998). Many samples of this clam-bed material were collected, but only a few small blocks were mapped in.

The surface of each vertebrate specimen was uncovered only enough to determine its lateral extent, then the exposed bone was coated with a consolidant – usually acetone-based butvar or vinac, although the cyanoacrylate 'Paleo-Bond' was also used.

Large specimens were extracted by trenching and undercutting the periphery with hand tools, until the block of matrix and the specimen within was on a pedestal above the surrounding matrix. When this was done, the specimen was covered in damp newspaper, and then in plaster- soaked burlap. After the plaster cured, the block was detached from its pedestal, flipped, and the bottom was similarly encased in the plaster jacket. Larger specimens were hand-carried by teams of two to four using a cargo net, and smaller specimens were carried in pack-frame or by hand – no mean feat, given the terrain.

Early in the excavation, small specimens were wrapped in aluminum foil, or placed in plastic bags. The Quarry team also experimented with duct-tape and fiberglass to protect a few of the small specimens, but this experiment proved that the more traditional techniques were far superior.

The team from Northern Kentucky University (NKU) introduced pre-plastered medical bandages for smaller specimens and this method largely replaced foil and bags, and burlap and plaster. Specimens in the pre-plastered bandage jackets were in excellent condition when they arrived at the lab.

13 Esker1/26/2009

Initially, a 2' × 2' string-and-spike grid aligned north-south was used to map the Quarry.

While this system facilitated map drawing, it proved to be imprecise, particularly in the measurement of the relative depth of each of the many specimens. Recognizing this deficiency,

NKU brought a total station to the Quarry to measure bearing and distance from the benchmark at the south end of the Quarry, near the top of the hill.

The total station substantially improved the accuracy and precision of each measurement, and allowed for detailed recording of bone orientation. The large number of specimens, the layering of both vertebrate and invertebrate bearing strata, and the general disarticulation of most specimens in this Quarry will benefit from the precision of the total station.

Vertebrate Preparation Techniques After opening the casts with a Stryker saw or knife, the matrix was carefully removed from each fossil with dental tools and air scribe. For particularly delicate specimens, acetone was applied directly to the matrix to soften it so it could be removed with a needle. As bone was exposed from the matrix, it was 'painted' with a thin solution of butvar in acetone. When a bone broke, it was repaired with a thicker, more glue-like butvar solution.

In one case (A.S.S. 577), the butvar was insufficiently strong to hold the bone together, and Paleo-Poxy, a putty-like epoxy was used instead. In general, epoxies and cyanoacrylates were avoided because of their poor reversibility. Thick coatings of the cyanoacrylate Paleo-

Bond used as a field-consolidant have proved especially difficult to remove because when cured, the consolidant is more durable than the bone. Attempting to remove the Paleo-Bond invariably pulls a layer of bone with it. Solvents return Paleo-Bond to its liquid form, but it re-cures as soon as the solvent evaporates. In addition, the 'accelerator' used in conjunction with Paleo-

Bond dyes the matrix and bone a bright blue, an effect of uncertain cause that does not appear to

14 Esker1/26/2009 be reversible. Despite difficulties encountered with some consolidants, preparation of the vertebrate paleontology material was a straightforward, if time consuming, process.

The vertebrate specimens are in the collections at the Cincinnati Museum Center.

Marietta College, as an affiliate of the Cincinnati Museum Center houses the specimens during cleaning and preparation, but personnel at the Cincinnati Museum Center and faculty and graduate students from the University of Cincinnati, led by Dr. Glenn Storrs, have ultimate responsibility for the growing collection. By mutual agreement, and following CMC specimen loan protocols, Marietta College may temporarily maintain possession of collected material as long as it is being used for educational purposes and may request casts of collected materials for display and teaching.

Quarry potential Specific projects that are part of the Quarry research effort include continued field collection, and systematics, paleoecology and taphonomy, sequence stratigraphy, stable isotopic study of bivalve shell material, sedimentology, clay mineralogy, and stable isotopic study of both the cyclical lake sediments and the transition from lake to floodplain during filling of accommodation.

Paleoecology, taphonomy, and sequence stratigraphy are ongoing as detailed in the publication record (Jeffery, Bertog, and Bishop 2004; Bertog et al. 2005, 2006) and in abstracts and manuscripts submitted and in preparation. Five detailed stratigraphic sections have been measured. The plan for stratigraphic study of the area includes expansion of the current correlation scheme to other nearby dinosaur accumulations and detailed sampling of additional measured sections to fully understand the three dimensional aspects of the stratigraphic framework.

15 Esker1/26/2009

The Quarry’s dinosaur deposit is overlain by a dark mudstone that is rich in unionid bivalves, offering the opportunity to analyze bivalve shell material for stable isotopes of carbon and oxygen to evaluate water chemistry and seasonality that may be preserved in the shell carbonates. Numerous recent studies on the materials from other sites in the Morrison have successfully recognized seasonality within invertebrate shell material using techniques outlined by Mii and Grossman (1994).

A Brief History of Morrison Formation Research

Before the 1860s, ’s fossil record was meager – primarily represented by a few trackways and isolated bones found along the heavily populated and highly vegetated East Coast. The ‘’ between Marsh and Cope beginning in 1858, revealed the American West to be one of the richest fossil resources on the planet. It may be argued that the crown jewel among these resources is the Morrison Formation.

In some places, the rocks of the Morrison are known as the Rainbow Beds for their striking red, white, purple, green, and pink layers, banding the landscape like giant agates. As fossil-bearing formations go, the Morrison is more than a dazzling jewel, it is big -covering more than 600,000 square miles and stretching from New Mexico to Montana, and from Utah to

Oklahoma. Figure 4 depicts the extent of the Morrison and identifies some of the important paleontological sites.

17 Esker1/26/2009

The formation has had many names over the , e.g., the Rainbow Beds and Dakota

Beds, but it received its current name from Cross in 1894 for the town of Morrison, Colorado

(Carpenter, 1998). Marsh and Cope discovered hundreds of dinosaurs and mammals in the

Morrison, but it wasn’t until 1916 that Charles Mook’s scholarly paper, Study of the Morrison

Formation provided a systematic analysis. Research on the Morrison has continued, making it one of the most thoroughly studied stratigraphic units on the planet. Given the breadth of research, it behooves the careful scientist to make a thorough study of the current thinking on the origins and inhabitants of this ‘Jewel of the West.’

Overview of the Morrison Formation The Morrison is a prolific fossil-bearing formation in the American West, deposited during the Kimmeridgian and stages of the Jurassic Period, during the regression of the Jurassic Interior Seaway across North America. The Morrison represents increasingly moist environments as one goes both up-section and westward. While the formation is dominated by floodplain deposits, there are at least two significant exceptions: the Tidwell Member represents a beach environment and the Recapture Member represents an erg.

The climate of the Late Jurassic was hot and dry, although some researchers assert that the upper half of the Morrison represents a slightly cooler, wetter climate than the lower half.

This does not appear to be the case for the Quarry, where the clay change above the site seems to signal a warming and drying of the landscape. The land was sparsely vegetated, with exceptions around bodies of water.

Lake and river-side flora included ginkgoes, seed-, and . Leaf impressions and fossilized wood are not uncommon and are generally preserved in thin lenses of coal. The deposition of the Morrison predates the advent of angiosperms by at least a few million years, and it predates the advent of grasses by almost 100 million years. Thus, dry floodplains were largely barren.

Large meandering rivers drained the basin into the Jurassic Interior Seaway to the east and north. The entire basin was dotted with oxbow and alkali lakes that were generally ephemeral. There were at least a few other large bodies of water farther to the east, most notably

Lake T’oo’dichi, straddling the Colorado/Utah border, and Dinosaur Lake (the name used in the

2005 Jeffrey & Bertog stratigraphic analysis of the Aaron Scott Quarry) in the San Rafael Desert

19 Esker1/26/2009 of Utah. T’oo’dichi in particular, was a substantial body of water, on the order of ancient Lake

Bonneville in size.

The fauna of the time was strongly dominated by dinosaurs, (particularly saurischians), but other vertebrate groups were also important. Fish were present, but these early fish would not have been familiar to modern residents of the Colorado Plateau. The largest piscine predators were the , some reaching a meter in length. Actinopterygian fish were also present, but were mostly confined to small forms. The first of the modern and evolved during this time, hopping into and crawling along the ancient waterways.

Crocodyliformes patrolled the Morrison, although none was as large as their modern counterparts.

On the land, only a few very primitive squamates had arisen, while most of the niches for -like creatures were dominated by the sphenodonts, represented today only by Sphenodon, the New Zealand . Poisonous egg-laying mammals were relatively common (Hurum et al., 2006). It had long been thought that Mesozoic mammals were small, unspecialized, shrew- like creatures, but recent finds in the Morrison have shown that by the Late Jurassic many highly specialized forms had already evolved; from burrowing mole-analogs such as Fruitafossor to swimming, beaver-tailed, otter-like creatures, e.g., lutrasimilis (Luo and Wibble,

2005; Ji et al., 2006) .

Invertebrate evolution continued apace, producing some of the first social , although the next great adaptive radiation of the group would follow the evolution and rise to supremacy of flowering (angiosperms) during the .

Literature Reviewed

From among the many published studies, there exist two exemplary references on the

Morrison Formation: the 1998 volume of 50 papers published in Modern Geology, and the 2004 volume of eight papers published in Sedimentary Geology. In combination, these texts provide a vivid picture of the current knowledge of the Morrison. The following is a recapitulation of the salient facts and findings presented in each volume.

The Implications of a Dry Climate for the Paleoecology of the Morrison Formation

Engelmann, Chure and Fiorillo 2004

This paper argues that the Morrison Formation was arid; with groundwater sources for significant bodies of water.

Interpretations of the Morrison’s mineralogy, environment of deposition, and diversity of have evolved with time. Initial interpretations of the environment were based on a faulty understanding of the lifestyle of the basin’s denizens. It was initially believed that most dinosaurs – the sauropods in particular – were too heavy to stand on dry land. Instead, it was believed that a body of water was needed to support and buoy-up their immense bulks. This misunderstanding caused early researchers to ignore the many lines of evidence pointing to a dry

Morrison.

Paleosols, the fossilized soils found in the Morrison are consistent with soils developed in modern dry climates. Morrison paleosols are rich in water-soluble minerals that would have leached from the soil in the lush tropical environment envisioned by earlier investigators. Basic sedimentology also provides unmistakable clues to the meteorology and environment of the

21 Esker1/26/2009

Morrison’s deposition. The Recapture Member represents a dune field – an environment that does not square well with visions of dark primordial swamps; and alkali lakes like the great

T’oo’dichi, which are typically found in semi-arid environments.

The analysis of oxygen isotope ratios in the Morrison’s paleosols further supports the argument for a predominately arid Morrison. Oxygen isotope ratio analysis is based on the presence of three common isotopic forms (atomic weights, 16, 17, and 18) of elemental oxygen.

While these isotopes behave in chemically identical fashion, their physical properties differ. 16O is lighter, and thus water composed of 16O evaporates more easily than that with 17O or 18O. 16O is known to make up a higher percentage of cloud moisture and rainwater. While still existing only in small quantities, 18O is present in higher concentrations in groundwater.

Calcite (CaCO3) in carbonate nodules in the paleosols of sedimentary rock form when calcium in the soil reacts with dissolved CO2 in water. The calcite in a hydrologic system dominated by rainwater or snowmelt contains mostly 16O. When the hydrologic system is dominated by groundwater, 18O concentrations are relatively higher. The carbonate nodules of the Morrison Formation contain a high fraction of 18O, indicating a climate with relatively little precipitation.

Computer climate modeling further bolsters interpretations of the Morrison as primarily arid. The Nevadan Uplift to the west of the Morrison would have caused a rain-shadow effect for most of the Morrison’s depositional basin - similar to the effect of modern mountain ranges.

Climate models indicate a strong two-season climate, with winter precipitation averaging no more than 2 mm per day, and summer rains of less than 1 mm per day, eliminating any plausible source for the vast amounts of moisture posited in early reconstructions of the formation’s ecosystem.

Regional Paleohydrologic and Paleoclimatic Settings of Wetland/Lacustrine Depositional

Systems in the Morrison Formation, Western Interior, USA. Dunagan and Turner, 2004

While the first paper in this series effectively advanced the argument that the Morrison was deposited in a predominately dry environment, this paper examines the nature of the portions of the Morrison that were known to be wet.

Earlier interpretations of the Morrison basin identified two major areas of standing water: a series of shallow carbonate-producing lakes in the east, early in the deposition of the formation, and the saline, alkaline Lake T’oo’dichi in the west, near the conclusion of deposition in the basin. The authors of this paper question (largely on semantic grounds) whether either of these two bodies of water was truly ‘lacustrine.’

On the basis of three separate lines of reasoning, Johnson concluded that most of the water in the Morrison Basin was ground-water – large aquifers recharged in the mountains to the west (1991). The authors of this paper add to the evidence that groundwater predominated the

Morrison by pointing to the absence of deltas in the eastern lakes and T’oo’dichi – an expected feature for any lake fed by surface water.

By hydrological definition, lakes (i.e., lacustrine environments) are fed by rain and snow, or surface water from streams, rivers or overland flow. Bodies of water fed by groundwater are palustrine environments: ‘wetlands.’ These hydrological definitions do not necessarily square well with colloquial vernacular where a lake is deep and a wetland is shallow. In hydrology, depth and surface area are not factors – a body of water can be ten miles long and fifty feet deep and still be palustrine if it is fed by groundwater. Similarly, a shallow pond that wets only the soles of the feet and has plants growing all the way out to the center is ‘lacustrine’ if the water source is not groundwater (Bates and Jackson, 1983).

23 Esker1/26/2009

The authors’ argument is not based entirely on semantics. Unique features of groundwater-fed (palustrine) bodies of water include a tendency of the water to be much higher in mineral content (or harder) than lacustrine water, because palustrine water has more opportunity to absorb minerals as it passes through rock and sediment.

The water in the eastern carbonate lakes would have become ‘hard’ because the aquifer supplying the lakes was in Paleozoic limestone. The water’s hardness however, was offset by the location of these lakes in an ‘open’ basin – where water was constantly drained out of the lakes into the sea to the northeast and refilled from the aquifer to the west. The water in these lakes was thus perfectly hospitable to life, and much of the Morrison’s aquatic fauna has been found in these waters.

Lake T’oo’dichi was a very different place – a ‘closed,’ basin where water entered through the aquifer but could only leave through evaporation. Because dissolved minerals do not evaporate with the water, the mineral concentration in the lake constantly increased. In addition,

Lake T’oo’dichi was closer to the western mountains, where volcanic ash falls were heavier and more frequent than in the eastern lakes area. When volcanic ash reacts with water, it produces salts and carbonates. Possibly as a result of the high mineral content, Lake T’oo’dichi seems to have been nearly sterile; the only major fossils known are a few salt-tolerant plants.

There were a few brief periods when T’oo’dichi’s waters were more hospitable – wet- spells lasting a few decades where rain and surface water dominated the basin. On the whole, however, T’oo’dichi may have been like a slightly less salty Great Salt Lake.

Author’s comment: The lake at the Quarry (named Dinosaur Lake by Jeffery and Bertog in their 2005 stratigraphic study of the site) may represent a third and thus far unique of water body in the Morrison. The lake’s most noticeable feature is the large lacustrine delta that

24 Esker1/26/2009 fed the lake. The presence of this delta suggests that the lake is the only true lacustrine environment yet discovered in the Morrison. This distinction may be the consequence of its extreme western position in the basin – where some of the water from snow, ice melt and rainwater running off the mountains to the west could have remained on the surface until it fed this lake, before soaking into the aquifer that waters the rest of the basin. Indeed, it may be that

Dinosaur Lake was a recharge point for the aquifer.

Jurassic “Savannah” – Plant Taphonomy and Climate of the Morrison Formation Parrish, T.,

Peterson, F., and Turner, C. 2004.

Even more than the animals that inhabit an environment, it is the plants that provide the best indication of the climate. Individual animals can move if the climate changes and becomes less hospitable, and then can return when environmental conditions improve. Populations of plants may be able to track climate change, but this advantage is not afforded to individual plants. The presence of autochthonous plant fossils is evidence that the climate was conducive to the growth of the preserved plants.

Early studies of Morrison plants, however, yielded results very much at odds with the picture of the Morrison seen in the rock – a hot and dry climate during the Morrison’s formation, perhaps cooling a bit toward the end of deposition. It is thus perplexing that one of the most ubiquitous plants throughout the Morrison is Czekanowskia, a known to be water-loving.

In fact, the list of Morrison plant taxa seems to indicate a wet environment. This is the point where earlier studies of Morrison plants stopped – and why they were incorrect. The early researchers accepted lists of taxa without examining where and how frequently those taxa were preserved.

25 Esker1/26/2009

Based on the findings of hundreds of paleontological expeditions in the Morrison, plant fossils are exceedingly rare and the authors posit three reasons for this condition: First, the mechanical degradation of plant material, pulverized by the currents, eddies and falls could explain the absence of fossils along rivers but does not explain the absence of plant fossils in the low-energy floodplains. Second, the complete oxidation of the plant remains through chemical and biological conversion of the plant material could align well with what we know about the

Morrison environment: arid areas seldom preserve plant remains because with the lack of anoxic groundwater, oxygen is too abundant. Plants are best preserved in the absence of oxygen – consider the stagnant peat bogs and the anoxic bottom waters of some lakes.

The third possible reason is that plants were not abundant or thick on the ground during

Morrison time. Previous authors have discounted this notion on the grounds that the gigantic sauropod dinosaurs must have required gigantic quantities of food. This led to a lush interpretation of the Morrison environment.

While sauropods doubtless required food proportionate to their bulk, it is incorrect to assume that only lush environments met this need. Many of the largest extant land animals live in semi-arid environments that are not lush. This fact may at first appear to be counterintuitive – large animals should prefer the most fertile areas - but while large size has its costs, it also confers a key advantage: mobility. Large animals can range across great distances for food, eating as they go. This is the strategy of the desert of Namibia, creatures the size of small sauropods that live in an environment even more arid than the Morrison. Provided their population density isn’t too high, gigantic animals can keep themselves fed on sparse vegetation.

Assuming that the Morrison was not a lush environment, the remaining question to be answered is what did grow there. The answer seems to be, “It depends when and where you are

26 Esker1/26/2009 in the Morrison.” Previous researchers treated the Morrison as a single homogenous environment, but the rock record of the Morrison indicates that this assumption is incorrect.

Environmental variation was present in the Morrison at all scales of space and time. This diversity helps explain why the wet-climate plant Czekanowskia is so relatively abundant in the fossil record.

Czekanowskia fossils are found relatively frequently because it was a wet-climate plant.

Dry climates are poor environments for the preservation of plant material – oxygen is too readily available. Wet environments that seal out oxygen are best for preserving plant remains, so plants in wet areas will be better preserved.

Consider the following thought experiment:

You observe a small oasis pond in the middle of a vast desert. In this desert, there are

one million cacti, and in the pond there are one hundred cattails. Of the cattails, twenty

are embedded in the oxygen-starved mud in the pond and are fossilized. Of the cacti,

most parts decompose and oxidize over time and only one spine survives in the rock

record. How will future paleontologists interpret the environment?

Fortunately, we have more Morrison fossil material than the unfortunate prospective paleontologist in this thought experiment. Away from the water, only scarce bits of leaf and the odd root cast can be found. The nature of these leaves and the size of the root casts seem to indicate that the majority of the floodplain had a sparse cover of small herbaceous or non-woody, plants. Larger shrubs and trees were confined to the margins of lakes and waterways. When the environment became wetter and cooler near the end of Morrison time, plants got a little bigger and thicker on the ground – even forming a little coal in a few small patches.

27 Esker1/26/2009

Climate models offer a way to visualize the appearance of the ancient Morrison. The models used atmospheric CO2 levels gleaned from soil carbonate studies, combined with atmospheric circulation models to determine that the Morrison averaged 1-2 mm of precipitation per day during the winter, and during the summer, less than 1 mm. As a consequence, most of the moisture in the environment was provided by groundwater. These conditions are replicated in a few places today, including the African Savannah – vast grasslands with the occasional bush and stands of trees lining local rivers and watering holes. There were no grasslands during

Morrison time; grasses would not arise for another 100 million years. Still, herbaceous plants - ferns, probably - would have taken the place of grasses. Modern ferns are not well adapted to arid environments, and even if the Morrison ferns were a little better suited to the savannah it is doubtful that they grew as thickly on the ground as modern grasses.

Reasonably lush conditions could have existed in the Tithonian as the environment cooled, but the non-woody plants still dominated the landscape. The Quarry again departs from the norm – the only plant fossil discovered thus far is the cone of a large , found a few meters above the dinosaur-producing layer. This fossil may represent a period after Dinosaur

Lake had largely filled in, leaving a marsh ideal for growing large trees (e.g., the cypress groves of the American South).

Reconstruction of the Upper Jurassic Morrison Formation extinct ecosystem – a synthesis

Turner, C., and Peterson, F. 2004.

Unlike the three papers detailed thus far, Turner and Peterson, 2004 is not limited to a single Morrison-related topic. Rather, it summarizes the balance of the work presented in this volume, chronicling the development of the Morrison Formation from beginning to end. This paper presents seven detailed maps giving an excellent view of the ‘Morrison Country’ over the

28 Esker1/26/2009 duration of its existence. The changes from the beginning of deposition in the basin in the

Middle Kimmeridgian to the twilight of the Morrison in the Early Tithonian vividly illustrate the considerable alteration of the landscape over the Morrison’s seven million lifetime. The idea of an unchanging, stagnant and fetid swamp, however vivid and primordial its image may be, must be discarded.

The estimated seven million years duration of the Morrison was derived by analyzing the

K-Ar ratios in volcanic sediment in the southern end of the Morrison basin. The proximity of volcanoes in Nevada and western Utah makes these sediments far more abundant in the south than in the north, but the absence of volcanoes farther north and east makes it difficult to estimate the age of Morrison sediments in , South Dakota and Montana. They are assumed to be of the same age based on faunal similarity, but thus far, absolute dating of the sediments has proven impossible. As the authors put it, “A certain amount of uncertainty is involved in the interpretation of the age of the Morrison.”

Previous papers have noted that the environment began to cool and moisten at the end of

Morrison time and this paper confirms that the trend continued into the Cretaceous. After a long pause in deposition, the first soils to be laid down over the Morrison are ‘gleysols,’ soils formed under wet conditions. The identification of this bed in Wyoming enabled geologists to extend the range of the Morrison in that area several meters up-section, increasing the Jurassic rock record at the expense of the Cretaceous.

The authors go into great detail on the tectonic setting of the Morrison that until now has been only vaguely understood; previous authors were content with the assumption that the folded mountains to the west, and volcanoes to the southwest provided much of the sediment that filled

29 Esker1/26/2009 the Morrison basin, and that the ‘Ancestral Rocky Mountains’ and the worn down nubs of

Paleozoic mountains in Colorado contributed sediment from within the basin itself.

A better-informed hypothesis adds to the complexity of the Morrison's genesis. Instead of the folded mountains formed by compression, there seems to have been a series of tension- related horst-and-graben ranges to the west. Erosion materials from the thermotectonically uplifted horsts appears to have been the more likely source of much of the sediment in the southern part of the basin, while the northern basin was likely filled with sediment from uplifts to the northwest. In this scenario, very little sediment originated from the ‘Ancestral Rockies,’ which may have been worn down to a peneplain by the time the Morrison began.

Lamentably, this solution poses major problems, most glaringly the fact that subduction was occurring off the west coast of the continent in a process that induces powerful compression forces, not tension. The answer appears to be that the subduction caused the tension. Water in the subducted ocean floor would have lowered the melting temperature of the rocks in the asthenosphere, resulting in an upwelling of magma. This upwelling, when it came in contact with the crust would have caused the crust to bulge upwards, with tensional forces that produced the horst-and-graben ranges.

Based on the distribution of volcanically derived sediments, it is very likely that the volcanoes were somewhere southwest of the Morrison depositional basin, but the nature of the volcanism is less clear. Until recently, it was assumed that the ash sediments originated from stratovolcanoes caused by subduction at the continental margin – analogous to the volcanoes of

South America today.

The chemistry and mineralogy of the Morrison ash beds, however, precludes this possibility. Rather, it appears that the ash originated from supervolcano calderas on the extreme

30 Esker1/26/2009 western edge of the continent, in the present day Sierra Nevada range. Stratigraphic work in that area has shown that the calderas underwent a series of major eruptions some time between 155-

148 Mya – a period that includes the entire deposition of the Morrison Formation. It does not seem unreasonable to suppose that the ‘clay change’ recorded halfway through the deposition of the Brushy Basin Member records the beginning of this outburst.

Turner and Peterson also include lengthy sections on the climate and groundwater systems in the Morrison, reiterate the information presented in the previous papers and present new data as well. Most interesting were a pair of studies on CO2 levels during the Morrison.

The first study assumed a four-fold increase over modern preindustrial levels, and combined it with estimations of the position of North America to determine temperature and rainfall. At the time, North America was about 5° farther south than it is today, and was rotated about 45° clockwise. Thus, the Four Corners region of the Morrison would have been where

Arizona’s southern border is today. The four-fold increase in CO2 would have put levels at about 1,120 ppm, raising temperatures (according to the authors' calculations) to about 68° F in the winter, and 104-113° F in the summer, nearly uniformly across the entire basin. The precipitation would have been less than 20 inches per year, or a few millimeters per day.

In fact, the scorching summer temperatures and dry climate would not have been very different from today – South Dakota, for example, records highs in the upper 90°s, and yearly precipitation is about 19 inches. What differentiates past from present is the seasonal temperature variation. In the Late Jurassic, seasonal variation was about 40° F, but in the

Holocene, the variation increased to 80° F. This may appear to be a minor point, but evaporation is not exclusively dependant on temperature, it is also a function of the period of temperature elevation. In modern times, the area that defines the Morrison basin experiences high

31 Esker1/26/2009 temperatures and high evaporation rates just three months of the year. During the Late Jurassic, rapid evaporation occurred year round. Given that roughly the same amount of rain fell then as now, it is clear that everything was drier in Morrison times.

The second study was similar to the first, but used carbon isotope ratios in carbonate nodules to calculate the amount of CO2 in the atmosphere. It showed that CO2 levels in the atmosphere were not four times higher than Holocene levels - they were eleven times higher.

Despite the huge increase in CO2 over the previous model, the peak temperature increases only slightly in this model, the seasonal temperature variation is smaller, resulting in winter evaporation rates that are nearly as great as in the summer months.

Further studies have shown that the arid environment of the Morrison basin was caused by ‘rain-out,’ rather than a rain shadow. The difference is that rain-out is caused predominately by the loss of atmospheric moisture during the trip from the coast, as opposed to moisture lost due to precipitation on the windward side of a mountain range in a process called orographic lifting. If a rain shadow was the cause of the low precipitation in the Morrison basin, we would expect uniform precipitation over the basin. Instead, it appears that the western most areas of the basin – e.g., the Quarry site – seem to have garnered more precipitation than areas farther to the east. The evidence of greater rainfall is seen in a higher concentration of surface water and river systems in the west, features that depend on meteoric water.

32 Esker1/26/2009

Vertebrate Biostratigraphy of the Morrison Formation Near Cañon City, Colorado, Carpenter, K. 1998. Biostratigraphy uses fossils that occur through a narrow temporal range to produce a formation’s chronology. Biostratigraphy is an important tool in invertebrate paleontology, because the numerous fossils of a given taxa can give a statistically significant indication of which animals lived when. Conversely, the small number of found specimens of any given vertebrate taxon means that this technique is seldom used by vertebrate paleontologists.

Consider the following situations:

An invertebrate paleontologist is studying two species of trilobite. There are roughly

50,000 specimens of each species and in nearly all cases, species A is found above species B.

The invertebrate paleontologist can thus be fairly certain that a specimen of species A is stratigraphically above species B.

In contrast, a vertebrate paleontologist is examining two species of dinosaurs, C and D.

Only one specimen of each animal is known to exist, and C was found above D. This single data set is insufficient to define the stratigraphic location of additional fossils. The ‘error bars’ for such an estimation would simply be too large. Error bars indicate the range of potential values or how certain one is about one’s measurements. If the range defined by the error bars of two measurements overlap, then it is not possible to say that the original positions are the norm. The error bars are typically set one standard deviation from the mean of the measured values, where the standard deviation is based on the distribution of a set of measurements. In practice, the range between the error bars in a small data set (just two measurements in this case) will be large enough to overlap, negating any statistical significance (Mendenhall and Reinmuth, 1974).

33 Esker1/26/2009

This example exaggerates the challenges presented by the limited vertebrate fossil record; the invertebrate paleontologist may have hundreds or thousands of specimens, and the vertebrate paleontologist may have only dozens. Biostratigraphy is useful in vertebrate research when the formation under study is unusually rich in diversity and abundance. Fortunately, the Morrison partially meets those criteria.

The author of this paper limited the scope of his study to the Cañon City area of

Colorado, an area of Morrison exposure with twenty-five vertebrate sites excavated between

1881 and 1998. This limited area was chosen because stratigraphic controls for the entire

Morrison Formation are inadequate.

The stratigraphy for the Morrison in the Cañon City area is easy to comprehend at a glance - the Morrison in that area is bounded below by Late rock, and above by Late

Cretaceous rock. The periods of erosion that produced these unconformities also destroyed much of the record for the early Morrison; only the Salt Wash and the Brushy Basin are represented here. The biozones the authors devised for the formation, however, do not correlate with the boundary between the members. Rather, they correlate with the clay change that is so prominent in the Morrison. Because of its simple stratigraphy, the relative positions of sites in the Cañon City area are well understood. Which taxa fall above, and which fall below the clay change from illite to smectite can thus be accurately measured, easily distinguishing biozones, should they exist. Figure 5 below is a graphic presentation of the results.

Dendrograms group similar samples together. The locations of samples grouped or clustered closer to the list of sites or taxa (in general) have greater similarity than those further away. The dendrogram in Figure 5 shows similarity among a few taxa (e.g., Elaphrosaurus,

Cerotodus, and Apatosaurus), but only limited similarity among vertebrate sites (e.g., Meyers

Sites 1 & 2, and Copes National Park). The dendrogram reveals some structure, but it appears to derive entirely from the productivity of the sites, not from taxa found nor where they were found.

While the author noted that Haplocanthosaurus is found only lower in the section and that Camarasaurus, while present everywhere, grows more common in the higher strata, there is no evidence of distinct biozones. In this author’s opinion, Cañon City, while rich by vertebrate standards, does not contain a sufficient number of occurrences to make such a claim. Based upon invertebrate standards, a much larger sample size is needed for a meaningful analysis of the

35 Esker1/26/2009

Morrison’s vertebrate diversity. Invertebrate paleontologists routinely work with samples that are at least an order of magnitude larger than could be had here.

Vertebrate Microfossil Sites and Their Contribution to Studies of Paleoecology. Brinkman,

D., Russell, A., and Peng, J. 2005.

The work summarized by Brinkman, Russell, and Peng in 2005 on Dinosaur Provincial

Park (DPP) in , Canada, was a significant influence on the multivariate analysis of the

Morrison presented in this thesis. Prior to Brinkman, Russell, and Peng, (2005) and beginning in the 1960s, researchers used microsites to characterize the ecology of the Cretaceous DPP, but it is only in the last decade and a half that novel statistical methods have begun to reveal much of the ecological structure in the DPP and . By examining differences in the makeup of each of the hundreds of quarries in and around the park, Brinkman and others have determined that:

 There were two distinct communities represented at DPP: coastal and upland.

 Ornithopod ornithischians (duckbills, etc.) preferred the dry uplands, while ceratopsians

generally preferred moist coastal environments, taking short seasonal migratory excursions

inland.

 Freshwater aquatic faunas are similarly divided between upland and lowland environments;

teleosts and frogs preferring the former, and gars and rays preferring the latter.

 Early placentals preferred uplands, and early , the coastal swamps.

36 Esker1/26/2009

This research and the collected set of factual information extracted from exploration of the DPP represent a fantastic wealth of data, gleaned from several hundred quarries. The

Morrison has been similarly prolific, with hundreds of quarries and thousands of specimens – thus it seems reasonable to expect similarly powerful results. In fact, three substantial differences exist between Alberta and Late Jurassic Colorado Plateau: documentation, bone bed diversity, and matrix.

Documentation. In producing their data set, Brinkman, Russell, and Peng benefited immensely from previous ambitious initiatives to document all quarries in the formation. Levi and C.M.

Sternberg began to mark important localities in the 1930s and Dodson and others attempted to relocate all of the originally marked quarries in 1971. New initiatives in 1981, and 1997 have resulted in the relocation and marking of more than 243 quarries in the DPP. Unlike researchers in the Morrison, Brinkman, Russell, and Peng had detailed geographic and stratigraphic data for nearly every site that has ever been excavated in the DPP Formation. Although several ‘mystery quarries’ have been rediscovered in the Morrison, several known quarries remain hidden2.

Bonebed diversity: Many of the quarries in the DPP Formation and Belly River Group are huge paucispecific bone beds, containing dozens or hundreds of individuals. In all of the Morrison there are only a few giant bone beds, the most common number of individuals in a Morrison

2In the absence of such an undertaking in the Morrison, it is more practical to rely on the Paleobiology Database (PBDB). While acknowledging that the PBDB is not comprehensive, it does contain the records of over two-hundred Morrison sites (Alroy, 2008).

37 Esker1/26/2009 quarry is one, and complete specimens are rare. Even so, there are a few very prolific Morrison sites that could be candidates for analysis.

Matrix. It is possible that Morrison microfossils with the same preservational potential as those in the DPP are not being found because Morrison sediment cannot be ‘bulk’ processed. The deposits in the DPP can be screened using water and a series of graduated mesh filters to quickly separate matrix from fossil and produce a concentrate that can be efficiently searched for specimens. In contrast, adding water to Morrison matrix usually causes the fossil to break into many small pieces. The Morrison is laden with expanding clays formed by the influx of volcanic ash in the Late Jurassic that force open tiny cracks in microfossils. As this author discovered, wet screening Morrison matrix always produces sub-millimeter-scale ‘bone grit.’

The preferred way to search for Morrison microfossils is to mechanically break the matrix to pea-gravel size and perform a visual search. Fossils can be found with this technique, as demonstrated by Dr. Zhe-Xi Luo of the Carnegie Museum of Natural History with his discovery of the bones of Fruitafossor (Luo and Wibble, 2005).

Paleoecology of Mollusks from the Upper Cretaceous Belly River Group. Johnston and

Hendy, 2005

Amidst the wide array of vertebrate fossils in the Quarry, it may be possible to overlook the other animals that perished at the site. An untold number of unionid clams were found in the layers of sediment above and below the vertebrate bearing layer. In Johnston and Hendy’s chapter in the Dinosaur Provincial Park volume, the authors successfully used clams to reconstruct environments of deposition, aided by the fact that freshwater bivalves have changed

38 Esker1/26/2009 very little since the Mesozoic. It is thus possible to deduce the nature of the environment of ancient bivalves by examining modern bivalve environments.

Johnston and Hendy identified two mollusk communities in the DPP Formation. The first was composed primarily of tiny sphaeriid bivalves. Modern sphaeriids are unusual among bivalves for being able to withstand seasonal drying. Sphaeriids in the DPP may well have been dwelling in ephemeral pools. Had such clams been present at the Quarry, they might have been an indication that the body of water at the site was of a similarly temporary nature.

Instead, the mollusks found at the Quarry were far closer to the second mollusk assemblage in DPP: the unionids. Like the sphaeriids, the unionids are alive today and can be found in many environments. However, unionids are most common in river settings. This is not inconsistent with the Quarry, which local stratigraphy and sedimentology suggest is a distributary channel in a lacustrine delta.

39 Esker1/26/2009

Faunal List

The bonebed at the Aaron Scott Site (Quarry) has produced hundreds of specimens, representing many individual animals. The bulk of these specimens however, remain unprepared in their plaster jackets. The volume of material collected from the Quarry every year is so great that it will take many years to prepare every specimen. By necessity then, this will be a preliminary faunal list.

Two numbering systems will be used in this list. The CMC VP #s are the official numbers for Cincinnati Museum Center’s vertebrate paleontology collection. The Marietta

College/NKU teams assign Aaron Scott Site numbers in the field. Each specimen begins with an

A.S.S. # and is not typically given a CMC VP # until it has been properly prepared. The index of

Quarry specimens in the CMC Vertebrate Paleontology Collection may be found in Appendix A.

The currently available partial list of Quarry field numbers may be found in Appendix B.

Reptilia Laurenti, 1768 Testudines Batsch, 1788 Cope, 1868 Glyptopsidae Marsh, 1890 Glyptops Marsh, 1890 Glyptops cf. plicatulus

Referred Specimens – Long bones A.S.S. 472, 280; neural bone A.S.S. 149b; carapace fragment A.S.S. 182; caudal vertebra A.S.S. 350 (field identification); scute impression A.S.S.

336.

Comments – Gaffney (1979) defines the family Glyptopsidae as cryptodire turtles in which the basisphenoid bone of the skull completely separates the pterygoids. He distinguishes Glyptops from Mesochelys (the other genus in the family) by Glyptops' hooked maxilla, narrower skull,

40 Esker1/26/2009 reduced contact between the nasal and prefrontal bones of the skull, and lack of xiphiplastral notch. None of these features were readily observable in the referred specimens. The author differentiated the referred specimens from the other Morrison genus, Dinochelys, by noting differences in the proportions of the neural plates of the carapace because Dinochelys has substantially narrower neural plates than Glyptops (width to length ratios of .893 and 1.041, respectively) (Hays 1908). A.S.S. 149b has a width to length ratio of 1.198, putting it far closer to Glyptops than to Dinochelys. The material from the Quarry was also found to closely resemble a Carnegie Museum of Natural History specimen CNM 3411 identified as Glyptops.

While shell ornamentation is similar in the two genera (particularly among juvenile specimens), the shape of the carapace bones is more like those in the Carnegie Glyptops, CNM 3411 than the

Dinochelys CNM 017 (listed under the nomen dubium Probaena sculpta).

Reptilia Laurenti, 1768 Sphenodontia Williston, 1925 Cope, 1869 Opisthias sp. Marsh, 1890

Referred Specimens – Right dentaries A.S.S. 311, 312, 380; maxilla A.S.S. 192; rib A.S.S. 335

(field identification).

Comments – This assessment was made by Dr. Nick Fraser, then at the Virginia Museum of

Natural History, now at the National Museum of Scotland, on the basis of casts of the above material. Despite having been found in close proximity, the specimens seem to represent at least three different individuals. All of the individuals appear to have been juveniles, being much smaller than any previously known Opisthias specimens (Fraser pers. comm. 2006). Dr. Fraser does note, however, the presence of significant tooth wear on A.S.S. 380 – usually present on older individuals. The current state of Jurassic sphenodont taxonomy prevents assignment to a specific level (Fraser and Wu, 1998). Further work on the specimens may help to determine whether they represent juvenile animals or a new taxon.

Jefferies and Bertog hypothesize that many of the taxa at the Quarry arrived at the lake shore in search of water during the same drought that lowered the base level of the lake (2005).

Certainly, this seems a plausible explanation for the dinosaurs, but does not square as well for

Opisthias. Long distance migrations of tiny terrestrial animals are very rare; modern , for instance, have a range of only a few hundred square meters (Walls 81). It seems probable that

Opisthias was a regular dweller of the lake or the littoral zone around it.

Referred Specimens – Tooth A.S.S. un#05P; dentaries A.S.S. 179, 221 (field identification); skull material A.S.S. 182 (field identification); vertebral centra A.S.S. 258, 290 (field identification); tooth A.S.S. Tooth A; cervical vertebra A.S.S. 153.

Comments – Goniopholis is a ‘waste-basket taxon’ for Late Jurassic crocodyliforms.

Preliminary identification was made based on comparisons with specimen CNM 1339 at the

Carnegie Museum of Natural History. Both this specimen and A.S.S. un#05P had prominent un- serrated ridges running down the length of the tooth. After examining the Eutretauranosuchus specimen (CMNH 8028) at the Cleveland Museum of Natural History, it seems more reasonable to tentatively assign the Aaron Scott material to this genus (Mook, 1967). The Goniopholis remains at the Carnegie (including CNM 1339), were somewhat larger and more robust than either the Cleveland Museum Eutretauranosuchus or the Aaron Scott Site Goniopholidae remains.

Diagnosis – The referred specimens were diagnosed by comparison with the specimens making up the composite Cleveland-Lloyd Allosaurus currently being exhibited at CMC. Allosaurus differs from the only other common large theropod in the Morrison Formation, , in that Allosaurus lacks longitudinal grooves, or sulci, on its teeth.

Referred Specimens – A.S.S. 376 3rd metatarsal.

Comments – The Carnegie collections were closed until mid-April of 2006, so comparisons were made with specimens at the Field Museum in Chicago. Dr. Peter Makovicky, the Field’s vertebrate curator concluded that the bone was a 3rd metatarsal from a Coelurus,

Comments – A detailed analysis of the rationale for the referred specimens above is not possible because the field crew took no notes to justify their assessments. Personal communication with quarry foreman John Bishop of Marietta College during the first year the Quarry was excavated leads the author to suspect that all robust diplodocid material was assigned to Apatosaurus.

While a more detailed assessment will ultimately be made, this report will tentatively hold to the field identifications.

A.S.S. 484 - 488.

Comments – As mentioned in the section on Apatosaurus, the field crew identified diplodocid material by arbitrarily dividing the material into ‘robust’ and ‘gracile’ categories. While this field identification will stand for the computer analysis, it may well be that only one diplodocid is present in the bonebed. If this change were carried through to the statistical analysis, it would likely increase the relative importance of ornithischians versus sauropods at the Aaron Scott Site, but have little effect on our picture of the Morrison as a whole. See the statistical analysis section for more detail.

A.S.S. un#05K.

Comments – The material above was diagnosed based on comparison with specimens at the

Carnegie Museum of Natural History (CMN 1949 and CMN 3392). Field identifications had previously attributed this material to both and Othnielia, but no characteristics could be found that distinguish it significantly from the far more common Dryosaurus. The most obvious differences between Dryosaurus and Othneilia are size and robustness. Othneilia (1.5 m) was roughly half the length of Dryosaurus (Sues and Norman, 1990; Marsh, 1877; Heinrich et al., 1993).

Referred Specimens – A.S.S. 204

Comments – This specimen has the classic laterally compressed centrum and tall, t-shaped neural spine that typifies stegosaurs (Galton, 1990). Anecdotally, there are two dorsal vertebrae from the Quarry, but only one appears in the official records. Presumably the second awaits preparation.

Statistical Analysis Until fairly recently, ecological analysis of the Morrison Formation has been qualitative

(Turner and Peterson, 2004). Indeed, vertebrate paleontology has gained little benefit from the burgeoning application of the statistical analysis techniques employed in invertebrate research, because sample sizes within a single site in vertebrate paleontology are too small. Only by looking at entire formations (as this study does) can sufficient data be acquired for analysis.

Thus the faunal analysis in this thesis will cover the entire Morrison Formation, instead of just the Quarry.

Cluster Analysis

Consider a 100 hectare field in North America, populated by many forms of fauna and flora. The density of its life forms may obscure the fact that it is not a homogeneous structure because certain plants tend to thrive in wet or shady areas and some animals prefer the fruits or shelter of certain plants. This geographic diversity continues through the soil to the microbiological level, however, it is obscured by the density and seemingly random nature of individual specimen locations, environments and other site characteristics.

Cluster analysis is a way of organizing observed data into meaningful structures to reveal underlying patterns in the data. As an analytical tool, cluster analysis can lead to the discovery of structure in data without the need for an explanation or interpretation of why or how they exist. Cluster analysis takes many forms, but for the purposes of this paper it is an analytical technique that graphically displays the similarities among samples using a tree formation or dendrogram (from the Greek for ‘tree’ and ‘draw’) where identical data elements are plotted at a zero distance from one another and less related data elements are plotted at greater distances.

The distance plotted in a dendrogram is based on a calculation of the Dice similarity coefficient

52 Esker1/26/2009 between two data elements on a multidimensional Cartesian graph. The method for calculating the Dice coefficient is described later.

Cluster analysis is an invaluable tool in both morphometrics and paleoecology. Cluster analysis requires data that is numerical and not qualitative, because the analysis depends on quantitative values for similarity.

Navigating Matrices The dendrogram requires the quantification of the numerical “distance” between two data elements, and matrix arithmetic simplifies the calculation of this distance. The data are placed in a two (or possibly, more) dimensional matrix where the number of rows (n) represents the total number of samples, and the number of columns (p) or other dimensions (y…) represent the number of variables. In a two-dimensional matrix for paleoecological data, the rows usually represent samples, or sampling sites, and the columns represent taxa.

Consider matrix X in Figure 14. The size of the matrix is described by n x p or 4 x 5, and the position of cell a is X1,A. where the row number is 1 and the column number is A. By tradition, the standard notation for this system is Xi,j, although the letters i and j could be replaced by any letters or symbols (Miller, pers. com., 2007).

53 Esker1/26/2009

Matrix Data Transformations There are times when the data in the matrix is not useful, e.g., the range of values is very small, very large, or in a form that is difficult to use. By performing the same operation on the data in every cell, the matrix may be changed or transformed without changing the relationships among the data elements. We will use log transformations and percent transformations to transform the hypothetical matrix in Figure 15.

Taxa 1 2 3 4 5 Sites A 2 4 8 16 32 B 4 7 14 12 28 C 22 2 8 1 1 D 24 0 1 3 440 Figure15:MatrixX,asimple4x5matrix.

Log transformation When the values in the matrix are spread over more than one or two orders of magnitude, the differences among smaller values tend to be obscured by the larger values. Logarithmic transformation enhances the differences among lower values and compresses the differences among larger values.

Consider the column X1 in Figure 15. Note that the difference between XA,1 and XB,1 is 2 and the difference between XC,1 and XD,1 is also 2. Yet the change from XA,1 and XB,1 represents a

100% increase from a value of 2 to a value of 4, and the change from XC,1 and XD,1 is only 10%.

An analysis of the raw data would tend to obscure the smaller values. To correct for this apparent effect, we can calculate the base 10 log of each value + 1, or log( 1). The result X i, j is in Figure 16.

The difference between XA,1 and XB,1 (0.22185) is now greater than the difference between XC,1 and XD,1 (0.03622), reflecting the significance of the doubling of values from XA,1 to XB,1 when compared to the much smaller change from XC,1 to XD,1.

Percent transformation Percent transformations correct for disparities in sample size. Consider the matrix in

Figure 17:

1 2 3 4 5 Total sample size A 100 25 100 25 100 350 B 4 1 4 1 4 14 C 25 6 25 7 25 88 D 112 22 114 20 111 379 Figure17:A4x5matrix.

The value in the column labeled ‘Total sample size' for each row is the sum of each element in the row. Note that there are extreme differences in sample size: XA,j = 350, XB,j = 14,

XC,j = 88, and XD,j = 379. For paleoecology purposes, these differences in sample size may not be meaningful, reflecting taphonomic conditions at the sample site, effort on the part of the collector, or other factors not relevant to the investigation, but would be a problem for the vertebrate paleontologist. While it may not be possible to eliminate all influences of sample size, the effect can be mitigated by evaluating each element in a sample relative to the sample size as described by the equation:

Similarity Coefficients Similarity coefficients quantify similarity between rows in the Q-mode analysis, or columns, in the R-mode. There are many similarity coefficients, and while the derivation and application of each of these coefficients can be interesting, only the Dice coefficient will be discussed here. The Dice similarity coefficient or SD is equal to the number of items in common between two samples, divided by the average size of the two samples (Miller, Pers, com., 2007).

C p S 2DB min X , X T D 1, j 2, j T p E  U C S Thus: i 1 , where D T is the number of items in S D p p 2DB min X1, j , X 2, j T  E i1 U B X 1, j B X 2, j i1 i1

p p  common, and B X1, j B X 2, j is the average size of the samples. Performing this operation on i1 i1 the matrix produces a new similarity matrix. The original matrix was n  p, but the new matrix is n  n. For the data in Figure 15, the Dice Coefficient produces the matrix in Figure 19, below.

A B C D A 1 * * * B 1 1 * * C 0.99 0.98 1 * D 0.97 0.96 0.96 1 Figure19:DicematrixgeneratedbythedatainFigure15.

56 Esker1/26/2009

This new 'similarity matrix' can be used to create a dendrogram and find clusters.

Dendrograms WPGMA vs. UPGMA WPGMA and UPGMA are methods for producing dendrograms from similarity matrices

(Miller pers. com. 2007). Begin with the matrix in Figure 20, below:

A B C D E F A 1 * * * * * B 0.45 1 * * * * C 0.7 0.65 1 * * * D 0.8 0.75 0.6 1 * * E 0.9 0.85 0.55 0.5 1 * F 0.4 0.95 0.45 0.4 0.35 1 Figure20:SimilaritymatrixfromtypicalDicematrix–Step1.

The name Weighted Pair-Group Method Arithmetic (WPGMA) refers to the result;

WPGMA is 'weighted' in favor of samples grouped later. Start by asking: Which two samples are most similar? Column ‘B’ and row ‘F’ of Figure 20 have the highest similarity at 0.95.

Begin the dendrogram knowing that ‘B’ and ‘F’ are linked at 0.95 (See Fig. 20). Next, average

B and F, put them under 'B,' and eliminate row ‘F’ and column 'F', as in Figure 21:

A B(+F) C D E A 1 * * * * B(+F) 0.425 1 * * * C 0.7 0.55 1 * * D 0.8 0.575 0.6 1 * E 0.9 0.6 0.55 0.5 1 Figure21:Similaritymatrix–Step2.

Repeat the process, adding to the dendrogram in Figure 25.

A(+E) B(+F) C D A(+E) 1 * * * B(+F) 0.513 1 * * C 0.625 0.55 1 * D 0.675 0.575 0.6 1 Figure22:Similaritymatrix–Step3.

57 Esker1/26/2009

Repeat the process, adding to the dendrogram in Figure 25.

A(+E+D) B(+F) C A(+E+D) 1 * * B(+F) 0.544 1 * C 0.613 0.55 1 Figure23:Similaritymatrix–Step4.

Repeat until the matrix is 2 x 2.

A(+E+D+C) B(+F) A(+E+D+C) 1 * B(+F) 0.544 1 Figure24:Similaritymatrix–Step5.

Plot the dendrogram so the y-axis represents similarity (from 0 to 1), and the x-axis gives us space to write the sample names. The resulting dendrogram is in Figure 25, below.

Figure25:AdendrogramforthedatainFigure20.

In the Weighted Pair-Group Method Arithmetic (WPGMA) averaging method, A and E have already been averaged together at the point when they are combined with D and averaged, so the result is weighted in favor of samples grouped later.

58 Esker1/26/2009

UPGMA (Unweighted Pair-Group Method Arithmetic average) compensates for this by using a weighted average rather than a simple average. The equation is:

    ((C S Ax ) (D S Bx )) S AB,x , where C is the number of samples in cluster A, and D is the C  D number of samples in cluster B. On the whole, UPGMA is superior to WPGMA, but both have a drawback. While dendrograms effectively represent similarity between samples higher up in the tree (where similarity is higher), the representation deteriorates toward the bottom of the matrix as each additional average is performed. However, dendrograms remain an effective way to express the relationships among samples, (or between variables, in R-mode).

It is also possible to produce a two way cluster analysis by plotting Q and R-mode dendrograms orthogonally. In paleoecology, this format can be a very useful way to see how groups of taxa change through a gradient of samples.

Analysis of the Upper Jurassic Morrison Formation

The Morrison Formation of the American West is famous for its vast abundance and broad diversity of vertebrate taxa. It is one of the most intensely studied fossil-bearing terrestrial formations in the world. The Morrison is an exceptionally promising candidate for close statistical scrutiny of vertebrate taxa. The beginning steps of this study are outlined below.

The Matrix Of 190 sites and 111 genera listed in the Paleobiology Database, 187 sites and 110 genera were selected for this analysis (Alroy, 2008)3. Three sites were excluded because they contained a single specimen and the excluded genera appeared only once. Three sites were added to the

3ThecompletelistofMorrisondatafromthePaleobiologyDatabaseisavailableinAppendixC.

59 Esker1/26/2009

analysis: The Quarry/Aaron Scott Site (Utah), Mother's Day Site (Montana), and Dodson

Diplodocus Site (Montana)4. One genus was added – leaves of the genus Ginkgo were found at

the Mother's Day Site (Ash and Tidwell, 1998).

The full and legible matrix requires a page width beyond the capabilities of most printers

and cannot be displayed here. However, text legibility is not essential to an understanding of the

data and indeed may be undesirable in this first round of analysis. In reduced scale, the matrix

looks like Figure 26, below:

Figure26:MatrixoftheMorrison.

Figure 26 is scaled to show the full matrix and is far too small to be legible, but at this

level a significant pattern is revealed – excessive white space. While it is true that there are

many sites and many taxa in the Morrison, most of the total abundance in the Morrison is

4TheDodsonDiplodocussitewaslaterexcludedfromallbutthemostinclusiveanalysesbecauseithasonlya singlespecimen.

60 Esker1/26/2009 concentrated in a very few highly productive sites, and even fewer very common taxa. This difference in sample sizes challenges systematic analysis and leads the paleontologist to ask,

“How much of this data is usable? Is there value in keeping sites that preserve a single animal or taxon with just one occurrence?”

Options include continuing the analysis with the full data set, excluding small sample sites and rare taxa, or including only the most common taxa in the most prolific sites. The decision was made to test all three options, conducting analyses using three different matrices.

The first matrix includes all taxa and sites, the second eliminates taxa with just one occurrence and sites with just one individual, and the third includes only the top twenty-two sites (thus including the Quarry, the site of primary study), and the top 20 taxa.

Data Transformations The small sample sizes in the Morrison dictated the application of a data transformation technique. Dinosaur National Monument is the most 'fertile' site in the Morrison, producing 102 taxa, but the majority of Morrison sites contained only 1 or 2 taxa. While sites at the lowest end of this range may be of little value, the percent data transformation might salvage the remaining the sites. By analyzing the fraction of the total abundance at a site represented by a given taxon, we can eliminate part of the disparity in sample size.

Similarity Coefficients The Dice coefficient was employed because it assigns twice the weight to matches and because it is free of the metric properties that make mean Euclidean distance inappropriate for finding data laden with meaningless zeroes (Miller pers. com. 2007).

Dendrograms

Figure27:Qmodedendrogramofallsitesandtaxa(insetenlarged)

62 Esker1/26/2009

The dendrograms were generated using UPGMA, to avoid the inherent weighting issues in WPGMA. Figure 27 shows the dendrogram of all sites and taxa in the Morrison. The image was compressed to conserve space and paper because it reveals little about the sites or taxa.

Reduced to patterns of lines, this figure reveals extensive 'chaining', an indication that it is based on useless or junk data - especially toward the bottom of the figure. There appears to be no relationship among most sites in this dendrogram, possibly because the very small sample size found in most Morrison sites overwhelms the corrective capacity of the percent transformation.

Even the more ‘structured’ area near the top reveals little – those sites merely contain single specimens of the same species.

Figure 28 on the following page is a Q-mode dendrogram of all taxa; again revealing extensive chaining. Most of the relationships among taxa at the top of the dendrogram appear to be a function of the overall prevalence of these fossils in the Morrison.

Figure29:Twowaydendrogram(allnonempty sitesandtaxa,truncated)withtwoormoreoccurrences

Figure 29 is a truncated two-way analysis of the data for all non-empty sites and for taxa

with two or more occurrences. The most commonly preserved taxa are on the left side and not

surprisingly, are found at most sites.

65 Esker1/26/2009

Eliminating the singleton taxa and depauperate sites caused no major changes in the dendrograms, and did not alleviate the chaining problem, but does provide insight into the possible linkage of Dryosaurus and Prismatoolithus by clustering these taxa and indicating the sites where they were found together. The clustering is potential evidence to support a long-held hypothesis that Prismatoolithus is an ornithischian egg (Alf, 1998). The taxa co-occur at the

Kirkland Site (2 specimens), Egg Gulch (2 specimens), and the Uravan Locality (9 specimens).

More aggressive data trimming resulted in a data set of the 22 most prolific sites, and the 20 most abundant taxa. Figure 30 shows the Q-mode dendrogram:

Figure30:Top22Sites,Top20TaxaQmode.

Thus far latitude, environment of deposition, and seem to have little to do with the structure; stratigraphy of Morrison sites is too poor to try to correlate. The chaining problem has diminished, but not quite disappeared. The remaining problem is that the clusters don't seem to correlate with any of the supplementary data for these sites. While the author plans to compare it

66 Esker1/26/2009 with additional supplementary data in the future, the R-mode again proved to be the most interesting. See Figure 31 below:

Figure31:Top20Genera,Top22SitesRmode.

As one would expect, the most common taxa co-occur more frequently. However, of greatest interest here is the strong co-occurrence of Diplodocus and Apatosaurus. Given that these genera are members of the same family, several hypotheses should be considered. Most interesting perhaps, is the possibility that these genera are sexual dimorphs of a single genus.

67 Esker1/26/2009

While remote, the recent discovery that many of the crested hadrosaur genera were sexual dimorphs makes it an intriguing, if unlikely, possibility.

There are substantial difficulties with this hypothesis. Single-taxa mass mortality sites like the Mother’s Day Site seem at odds with this interpretation (Myers and Storrs, 2007) and there remains a lengthy history of separate taxa periodically challenged by researchers looking to reduce, rather than expand the numbers of known vertebrate taxa. Intriguingly however, gender specific bonebeds are known to occur in extinct taxa such as Mammuthus columbi. These accumulations are a result of the segregation of adult males from the matriarchal herd

(Agenbroad and Mead, 1994; Hoppe, 2004). Such bonebeds either contain a mixture of adult females and juveniles of both sexes, or males only. Accepting this hypothesis as an explanation for monospecific Diplodocus sites would allow us to make similar inferences about their behavior.

Diplodocus and Apatosaurus are, however, in different subfamilies. Moreover,

Diplodocus is morphologically more similar to Barosaurus than it is to Apatosaurus. It might be more appropriate to hypothesize that the common co-occurrence of these taxa are the result of a mixed herd structure, as is seen in modern African ungulates.

68 Esker1/26/2009

Figure32:Top22Sites,Top20Genera2Way.

While there is a visible pattern in Figure 32, from the top left to about the center, the increase in occurrences in the bottom right of this Q-mode dendrogram and challenges systematic interpretation. However, the taxa to the right are generally smaller, and more often thought of as aquatic. Several of the ornithischian dinosaurs are also closely grouped.

Conclusions While the results are far from definitive, there is sufficient structure in the data to make further analysis worthwhile. Examining only the most fruitful sites and only the most abundant taxa is likely to be the best option to produce meaningful results.

POLAR ORDINATION

Description of Technique

Consider again the same 100 hectare field examined in the study of cluster analysis. Thanks to that technique, it was possible to gauge and graphically represent the similarities of individual sampling sites across the field. Polar ordination takes this process to the next level: determining the existence of a gradient of composition in sites in the field, e.g., east to west, or north to south

(Miller, pers. com., 2007).

Projections Polar ordination is a technique for analyzing the patterns that result from projecting points in higher dimensional space into one, two, or three dimensions. Consider a situation where there are three sites (samples) with abundance values for two taxa (variables).

Here is the Q-mode similarity matrix:

Taxon Taxon One Two Site A 1 1 Site B 5 1 Site C 2 4 Figure33:Asmall,Qmodematrix.

In this example each sample represents a point, with the coordinates defined by the abundance of each taxon. Figure 34 on the following page is the resulting graph.

70 Esker1/26/2009

Figure34:Sitesintwodimensionalspace.

At this point the data is in two dimensions, but it can be ‘projected’ down to one dimension by plotting the points out as a triangle. See Figure 35.

Figure35:Sitesinonedimensionalspace.

Begin by selecting an axis. For ease of reading and interpretation, the two points most different from each other are best; in this case, points A and B. The distance from A to B will now be axis Z.

The other letters on the triangle represent:

X = The distance between A and C Y = The distance between C and B a = The projected position of C along axis Z b = The distance from a to B e = The distance from ‘a’ to the real position of C, perpendicular to Z

71 Esker1/26/2009

Given all of this, the following holds true:

a 2  e 2  X 2

In this case, ‘a’ is 0.1, and e is 3.16. In this example, a point was projected from a plane onto a line, but it is entirely possible to project points from a volume onto a plane, or points from higher-dimensional space into a volume using a similar process.

Choosing Endpoints The several methods of polar ordination are distinguished by how their endpoints are selected; and endpoint selection radically affects the resulting plot. In Bray and Curtis’ original method, the endpoints for each axis were the pairs of points with the highest distances from each other (Bray and Curtis, 1957). This technique gives rise to two difficulties: first, the probability that the two axes will cross at a highly acute angle as shown in Figure 36.

Figure36:Nonperpendicularaxes.

72 Esker1/26/2009

In this case, the axes are so close together, they may be ‘measuring’ the same property.

Alternately, the points selected may be far apart because they are outliers, as in Figure 37.

Figure37:Outlierbasedaxes.

The result is that much of the data is compressed to the point of un-interpretability.

There are several methods for avoiding outliers and selecting near-orthogonal axes: a technique called variance-regression may help solve these problems (Miller pers. com., 2007). Variance is the difference of a given value from the average value. The following equation describes the calculation of variance.

Variance-regression selects endpoints that maximize the variance – in other words, endpoints that tend to spread the data out. Since both outliers and near – parallel axes tend to decrease variance (by compressing the data), the variance regression method protects against these problems – outliers are recognized as such because they decrease variance.

Interpretation There are several challenges in interpreting polar ordinations. The first and most tedious challenge is determining the axes. Recall that the axes were chosen so as to maximize the distance along each axis while avoiding the outliers – they were not chosen on the basis of the supplementary data. Thus, the axes could be anything, e.g., geographic position, environment of

73 Esker1/26/2009 deposition, lithology, or age. The only way to determine what the axes represent is to comb the supplementary data to identify patterns that match the axes. This can be a tedious and unrewarding endeavor if the supplementary data lacks detail or is nonexistent.

The second challenge is finding patterns in the importance of particular taxa along an axis. This is done using a technique called linear regression.

74 Esker1/26/2009

Figure38:LinearregressionanalysisofApatosaurus.

The polar graph in Figure 38 tracks the relative abundance of the genus Apatosaurus – members of this genus have been discovered in several sites in the Morrison Formation. The graph in the upper right is the ordination itself. In this Q-mode analysis, each triangle represents a site, and the size of the triangle represents the relative abundance of Apatosaurus in that site.

75 Esker1/26/2009

The graph below the ordination plots ‘Axis 1’ versus relative abundance, while the graph to the left plots relative abundance versus ‘Axis 2.’ The straight lines on each of these graphs represent the overall trend derived through linear regression of the data along these axes.

Transformations In most cases, the raw data must be transformed to make best use of the information contained within. As before, the Q-mode analyses were percent transformed to correct for differences in sample size. Miller (pers. comm. 2007) recommended a percent-max transform of the R-mode analyses, increasing all values to the same maximum to avoid potentially misleading similarity measurements affected by size.

Morrison Ordinations Each of the three sample sizes was analyzed using both Q and R-mode analysis, with three methods each for selecting endpoints. Special note was made of linear regressions of taxa across sites that produced ‘r’ values above 0.6. The result is the set of 94 graphs included with this paper. It is not useful to examine each graph in detail; only a few are of interest, e.g., the Q- mode Bray-Curtis plot for the most prolific sites and the most common taxa in Figure 39, below.

76 Esker1/26/2009

Figure39:TopSites,TopTaxaBrayCurtisOrdination.

The Bray-Curtis method does not manage outliers effectively, so it will not be used for analysis of larger samples. Still, it was effective with a small number of samples. Of principal interest here is the relationship between the Quarry and the other Morrison sites – it is very near the polar center and closely grouped with 57913, the Rainbow Park Microsite at Dinosaur

National Monument, nearby. In general, however, geographic position seems to have little relationship to either axis. For example, there is no factor in the supplementary data for the

77 Esker1/26/2009

Morrison sites that correlates well with these axes, regardless of the endpoint selection method and the number of taxa and sites analyzed.

The variance-regression version of the same data should banish endpoint selection problems introduced by the Bray-Curtis method (Miller, pers. com., 2007), as illustrated in

Figure 40.

Figure40:TopSites,TopTaxaVarianceRegressionOrdination.

The axes were rotated counter-clockwise, but the relationship with Rainbow Park still holds – both produce an abundance of microvertebrate remains. In addition, the Quarry is close

78 Esker1/26/2009 to Reed’s Quarry 11 at in Wyoming, another site rich in small-bodied taxa. More revealing are the trends within the various taxa in Figures 41 and 42.

Figure41:VarianceRegressionAnalysisofCamarasaurus

79 Esker1/26/2009

Figure42:VarianceRegressionAnalysisof.

The unknown characteristic the sauropods find suitable at the left side of the graph is evidently not to the liking of the aquatic choristoderes. However, there is no discernable

80 Esker1/26/2009 environmental gradient from one end of the axis to the other. The R-mode analysis in Figure 43 for the smaller data set proved to be more revealing.

Figure43:TopTaxa,TopSitesPolarOrdination.

The three groups of interest are revealed in polar ordination. The closeness between

Apatosaurus and Diplodocus first identified during cluster analysis holds up nicely. It has previously been suggested that various diplodocoid taxa (specifically Diplodocus and

Barosaurus) were sexual dimorphs of each other, but the idea was dropped as fanciful (Senter,

2007). Another close association can be seen between Stegosaurus and Camptosaurus. While they are rather differently shaped creatures, they are in the same size range and they have similar

81 Esker1/26/2009 dentition, so perhaps the correlation is not far-fetched. Finally, three similar mammals Docodon,

Dryolestes, and Laolestes are neatly clustered at the opposite end of Axis 1 from the Diplodocus-

Apatosaurus pair.

The Quarry is near the center of the graph in Figure 44, and appears as expected, in a group with other micro-vertebrate sites. The empty upper right quarter will require additional analysis, however.

As can be seen in Figure 46, the relative abundance of the apex predator Allosaurus increases as the relative abundance of its assumed prey Camarasaurus decreases. This counter- intuitive relationship demands an explanation. A possible explanation is that the primary diet of

84 Esker1/26/2009

Allosaurus consisted of smaller ornithischian dinosaurs, instead of the much larger sauropods.

Ornithischian variance-regression increases in the same direction as Allosaurus’.

PRINCIPAL COMPONENTS ANALYSIS OF THE MORRISON

Analysis of the Morrison Formation A significant portion of the data available from vertebrate paleontology sites in the

Morrison has proven unusable – too many sites contain too few genera, and too many genera are found at too few sites. Transformations and abridgments have teased out more concrete results, but only one combination has yielded anything of interest – a data set confining itself to roughly the top 10% most prolific sites and the top 10% most abundant genera. The most promising results were obtained when a percent transformation was applied to the data for Q-mode analyses, and a percent-max transformation for the R-mode.

While some structure was shown in the Q-mode analysis, the R-mode produced the most interesting results, showing possible links between a small ornithopod and egg, and an undefined relationship between two sauropod dinosaurs. On the whole though, these exercises were disappointing; the cluster analysis offered no clear explanation for the site clustering, and the polar ordination analysis offered no basis for the gradients detected through this technique.

Fortunately, other analytical tools are available.

Principal Components Analysis - Description of Technique Principal components analysis (PCA) is a technique for finding the ‘components’ of a multivariate matrix that account for much of the variation in the data, similar in goal to polar ordination. It differs from polar ordination however, in the way it selects the axes and in the unusual way it combines Q and R-mode analyses (Miller pers. com., 2007). Instead of looking

85 Esker1/26/2009

among the samples for suitably different endpoints for the axes, PCA uses a form of multivariate

linear regression to generate best-fit axes. That is, it finds axes with the highest possible R2

values, thus dispensing with the need to find non-outlier endpoints.

As in polar ordination, samples are projected to a two-dimensional scatter-plot from

multidimensional space. Unlike polar ordination, PCA also displays R-mode data in the form of eigenvectors, i.e., vectors with length and direction. The length of the vector is called the eigenvalue, a measure of the overall contribution to the structure in the matrix. The direction of the eigenvector indicates whether the variable is correlated negatively or positively.

Eigenvectors indicate how much of the variation in a particular component is caused by a specific variable.

In addition to the main scatter-plot, PCA produces two subsidiary graphs. The ‘scree graph’ (see Figure 47) plots the total eigenvalue versus the number of components in a curve that is typically L-shaped. The steepest portion of the curve indicates components that contribute to the structure of the data. Components in the shallow part of the curve are not most significantly useful in explaining data variation.

The second graph shows the ‘loadings’ of each of the variables based on the eigenvalues for each variable in relation to each component. The loadings graph is particularly useful in testing hypotheses on the meaning of each component.

The analysis on the full data set produced the scree graph in Figure 47. The scree graph identifies the components that are worthy of further analysis and in this case, only the first four components are important. Thus, the examination of vectors will be limited to components 1 through 4.

Components Figure48:Component1loadings

Figure 48 is the loadings for the first component. Most of component 1 is controlled by the abundance of the aquatic turtle Glyptops. The other positive loadings are for the

Goniopholis, the aquatic Cteniogenys, the docodont mammals, Docodon, Laolestes and

Amblotherium, and the dryolestid mammal, . The only well preserved docodont,

Castorocauda lutrasimilis from China, is aquatic (Ji, Luo, Yuan, and Tabrum, 2006).

Additionally, all genera with negative loadings have been assumed to be terrestrial. On this basis, the tentative conclusion is that the first component represents terrestrial vs. aquatic habitats.

88 Esker1/26/2009 Loading Loading

Components Figure49:Component2loadings.

Figure 49 shows the loadings for component 2. Much of the variation on this axis is provided by a strong negative correlation with the small sphenodont diapsid, Opisthias. Each of the other animals with a negative eigenvalue was also very small bodied, and those with the largest positive eigenvalues were huge creatures, with one exception, the turtle, Glyptops. The author postulates that component 2 registers a difference between sites preserving micro- and macrovertebrates. Glyptops may be grouped with much larger animals because of the preservation of its armored skeleton.

Together, the data from the first two loadings are illustrated in Figure 50, above. With the sites superimposed, most sites that have been proclaimed microsites have y-axis values of less than zero. The second prediction is more difficult to prove: research on the environment of deposition in Morrison sites is insufficient to conclude that the sites on the right are wetter than sites on the left.

Figure52:Component4loadings.

Figure 52, however, is promising. This graph displays the loadings for component 4, the last component of the scree graph identified as significant. The most significant loadings are negatives belonging to Stegosaurus, Dryosaurus, and Camptosaurus. Othnielia has a slightly less impressive, but still negative loading. These four are ornithischian dinosaurs, the sparser of the two groups of Jurassic herbivorous dinosaurs.

92 Esker1/26/2009

The Apatosaurus, Diplodocus, and Camarasaurus have relatively high positive loadings and are members of the other herbivorous group, the sauropods. The loadings of the other taxa do not correlate with any taxonomic or ecological relationships that the author could identify.

While the meaning of component 4 is not as clear as those of components 1 or 2, there is some factor at each site that is either attractive to ornithischians but repellant to sauropods, or vice-versa. While there are a multitude of well understood physical differences between ornithischians and sauropods and a plethora of behavioral differences that may never come to light, the author speculates that diet may have played a significant role. The basis for this speculation is the fact that ornithischians and sauropods were equipped differently to process food – the former with shredding, serrated, leaf-shaped teeth, versus simple peg or spatulate teeth and grinding gastroliths for the latter.

A hypothesis that these differences in masticatory and digestive hardware represent differences in diet, might lead to the conclusion that sites dominated by ornithischians contained flora more palatable to them, while the sauropod sites were richer in herbage that was more to those behemoths’ liking. However, this hypothesis will be difficult to test because the research and literature on Morrison is limited, and inconclusive, possibly owing to the poor preservation of plant life in the Morrison.

PCA of the Morrison Formation did not reveal geographical or temporal gradients in abundance, but several other interesting patterns did emerge. There appears to be a strong gradient between sites preserving micro- and macrovertebrates, probably reflecting differing taphonomic or environmental conditions. The author suspects that a more detailed study of the lithologies of the different sites would reflect this.

93 Esker1/26/2009

There is also a clear distinction between aquatic and terrestrial sites in the Morrison, although there does not seem to be any geographic correlation between wet and dry sites. This may be indicative of a patchy distribution of water bodies across the Morrison Basin. Finally,

Morrison sites containing herbivorous dinosaurs seem to be either ornithischian- or sauropod- dominated. This may conceivably reflect a difference in food among sites.

While these findings are of interest, it is undeniable that the study of Morrison ecology would benefit from a more rigorous collection of subsidiary data. Of particular use would be accurate information concerning the stratigraphic position, absolute age and environment of deposition at each site, and an accurate census of all taxa – plant and animal, vertebrate and invertebrate. It is virtually impossible to understand or analyze the fauna out of context with the environment and surrounding flora. A genuinely photo-accurate image of the ecology of the ancient Morrison Basin will have to wait until every site – new and old, is more thoroughly investigated and understood.

Summary

Faunal Analysis and Paleoenvironment of the Aaron Scott Site

Does the Aaron Scott Site (Quarry) represent a rare environment in the Morrison

Formation because it was a wet place for thousands of years? A review of the faunal list for this site, replete with clams, crocodyliforms, and turtles, is sufficient to inform the reader that water played a significant role in its natural history. However, the same might be said for most of the

120 Morrison sites under consideration in this study. Seventy-six sites clearly represent fluvial and lacustrine/palustrine environments of deposition, because there is a strong bias for preservation in such environments compared to the geographically extensive dry floodplain deposits of the Morrison. Thus, the simple presence of an aquatic environment of deposition at the Quarry is neither unusual nor noteworthy.

Yet the environment of the Quarry is remarkable because this site represents the distributary channel of a lacustrine delta on a large perennial lake an environment a fact that was unusual on two counts. First, large perennial lakes were exceedingly rare in the Morrison where high temperatures, meager rainfall and low humidity limited the opportunities for long-term lake formation. The only previously well known example is Lake T’oo’dichi, a site that is now believed to have been a large salty marshland – not lacustrine, but palustrine.

The second and most remarkable feature of the strata in Quarry is their well-developed delta facies. To date, the only other delta deposits found in the Morrison Formation have been in the lower Tidwell and Saltwash members on the eastern border of the formation, on the boundary of the Jurassic Interior Seaway. In fact, the absence of deltas on Lake T’oo’dichi persuaded

Turner and Peterson to conclude that the still-water environments of the Morrison were ground-

95 Esker1/26/2009 water fed wetlands, rather than true lakes. The lake represented at the Quarry may well prove to be the first true river-fed lake in the Morrison.

Given these singular features, the unique nature of the Quarry’s environment is cause to postulate that characteristics of the fauna may also be unique. This hypothesis was evaluated by compiling a faunal list from the fossils discovered at the site, a process that is ongoing. The backlog of collected material continues to grow as well over 100 fossil specimens are retrieved from the Quarry each year. The site will continue to produce research material for many years, forestalling the completion of a comprehensive faunal list for a decade or more. Thus it is all the more remarkable that the relatively small fraction of collected material examined thus far has produced nine genera, and a minimum of eleven individuals.

Multivariate Analysis of Morrison Fauna The body sizes for the current Quarry faunal list range from fifty-ton sauropods to 200- gram sphenodonts. Superficially, this appears to be a strange pairing, but multivariate analysis provided a highly reliable methodology to gauge the similarity of the site’s fauna with that of other sites. The Quarry clusters closely with other prolific ‘microsites,’ in the Morrison, that were deposited in aquatic (but not necessarily in lacustrine/palustrine) settings. Indeed, Dinosaur

National Monument, a fluvial site, is the closest match with the Quarry, eliminating the single leg supporting the initial hypothesis: that the fauna in a large perennial lake would differ significantly from fauna elsewhere in the Morrison.

However, this result leads to the conclusion that certain taxa, particularly small bodied animals, are most often found in aquatic environments, with similar likelihood for running or still water. This conclusion is consistent among deltaic, fluvial and lacustrine or palustrine sites, but is likely dependent on flow regime. The swift waters of a river narrows would likely result in

96 Esker1/26/2009 disarticulation. This conclusion raises an interesting question: were these animals genuinely more common in aquatic and littoral areas, or is their representation there an artifact of higher preservation potential in those environments? Lakes are famous for the quality of preservation of a wide range of animals and plants: the Eocene Green River Formation and the Cretaceous shales of Liaoning are excellent examples. It is likewise true that rivers can overwhelm, drown and entomb numerous animals during ill-timed crossings, e.g., the bone beds of Dinosaur

Provincial Park.

Are these examples sufficient to explain the small-bodied taxa that were preserved in the

‘damp’ areas of the Morrison? The answer to this question is clearly “No.” Evidence supporting this conclusion can be found in sites like Dinosaur National Monument which represents a braided stream environment. The many large dinosaurs at the site were apparently killed and deposited during a flood event when they were washed downstream and ‘beached’ upon several large sand bars. Moderate transport best explains the presence of so many behemoths in so small an area. However, this explanation leaves a good deal to be desired regarding the five smaller taxa at the Quarry – and the smaller taxa found at Dinosaur National Monument, because it is nearly inconceivable that an animal as small as the sphenodont Opisthias (22 cm total body length) could remain intact during lengthy transport in such an environment.

A third alternative lies in the research of Jefferies and Bertog (2005) who hypothesize that many of the taxa at the Quarry were attracted to the lake shore in search of water during a drought that lowered the base level of the lake. This seems a reasonable explanation for the presence of dinosaurs, but must work as well for little Opisthias. Unfortunately, it does not.

Long distance migrations of terrestrial animals of Opisthias’ size are very rare. The tuatara, a

97 Esker1/26/2009 modern relative, has a range of only a few hundred square meters, suggestive of an ancient

Opisthias that lived by the lake or in the littoral zone around it (Walls, 1981).

The multivariate analysis appears to support a long held suspicion among paleo-oologists in their study of fossil eggs, that the ootaxon Prismatoolithus is the egg of Dryosaurus. In cluster analysis, the similarity coefficient between the two is a promising 0.84. Several other small-bodied taxa not yet known from the Quarry may prove to be largely aquatic as well. In multivariate analysis there is a strong association of the docodont mammals Docodon and

Laolestes with Opisthias.

Again, taphonomic bias may be responsible, but several of these mammals have been found in sites representing a high energy environment. As with Opisthias, this makes it unlikely that they could have been transported any great distance – high energy environments are extremely destructive to micro vertebrate material. Still, until recently only inference suggested an aquatic habitat for these animals; mammalian remains in the Morrison are rare and generally scrappy. Recently however, the most complete docodont known was found in China.

Castorocauda lutrasimilis is clearly an aquatic animal – its very name means, “Beaver-tailed and otter-like.” It may well be that the flattened tail and webbed feet of this creature are common to all docodonts, but that will not be apparent until more complete remains are found in other parts of the world (Luo and Wibble, 2005).

The multivariate analysis yielded a few unexpected results as well. Perhaps most intriguing is the close (0.73) similarity between Apatosaurus and Diplodocus. These dinosaurs are closely related, both being members of the Diplodocidae. Diplodocus was longer and more gracile, Apatosaurus shorter and more robust.

The differences seem clear, so what is the basis for this high similarity? One cannot derive definitive conclusions without a careful morphometric study, but is one possibility, and would certainly explain the appearance of each in nearly equal numbers.

Diplodocus, however, is more morphologically similar to other taxa than it is to Apatosaurus, however, so another explanation – such as mixed herd structure – is more likely.

Other patterns are more difficult to explain. Why is Allosaurus most common in sites depauperate in sauropods, their potential prey? The answer to this question could be dependent on a yet another pattern: the ornithischian plant eaters (e.g., Stegosaurus, Camptosaurus) also increase in numbers as the sauropod numbers decrease. Sauropods and ornithischians have radically different dentition, probably reflecting their different diets. Allosaurus increases in frequency right along with the ornithischians – a possible indication that these more manageable herbivores, and not the lumbering sauropods, made up the bulk of their diet.

Conclusion and Future Research The original hypothesis that the Quarry should produce a unique vertebrate fauna because of its identity as the only perennial lacustrine environment in the Morrison Formation, failed its tantalizing premise. Like the deep oceanic environments surrounding undersea vents that produce remarkable and bizarre organisms, it was opined that the Quarry’s faunal population and diversity might be unlike any other Morrison site. Instead, the Quarry’s fauna resembles that of other bodies of water in the Morrison; no unique taxa have yet been found among the Quarry’s fossils. The conclusion that the Quarry was not unique is based on a series of analyses of the

Quarry’s fossil content and the Morrison’s larger fossil record, using the data collected in the

Paleobiology Database (PBDB). However, the full content of this site has not been explored and

99 Esker1/26/2009 the potential remains that the Quarry may yet yield additional small mammals and significant microfossils.

The same analyses, however, bore out the second hypothesis: the Morrison Formation represents multiple environments, which are in turn host diverse animal communities. Clear distinctions seem to exist between wet and dry habitats, and between sauropod and ornithischian dominated communities. While multivariate analysis failed to verify the unique nature of the

Quarry, it did yield a small set of intriguing possibilities involving the sauropods Allosaurus and

Apatosaurus, the ornithischians, Dryosaurus and Stegosaurus, and the docodont mammals.

Additional work on the biostratigraphy and paleobotany of the Morrison Formation will doubtless fill in the details on this broadly drawn picture of an ancient ecosystem.
