The Late Cretaceous–Early Paleogene genus Mesocyparis McIver et Basinger, which obviously embraces a natural group of closely related species, was a significant component of the vege- tation in the middle and high latitudes of eastern Asia and western North America. The range of the genus tes- tifies to terrestrial Transberingian connections between the continents during the Cretaceous warming phases.

A Phylogenetic Analysis of the Basal Ornithischia (Reptilia, Dinosauria)
A PHYLOGENETIC ANALYSIS OF THE BASAL ORNITHISCHIA (REPTILIA, DINOSAURIA) Marc Richard Spencer A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements of the degree of MASTER OF SCIENCE December 2007 Committee: Margaret M. Yacobucci, Advisor Don C. Steinker Daniel M. Pavuk © 2007 Marc Richard Spencer All Rights Reserved iii ABSTRACT Margaret M. Yacobucci, Advisor The placement of Lesothosaurus diagnosticus and the Heterodontosauridae within the Ornithischia has been problematic. Historically, Lesothosaurus has been regarded as a basal ornithischian dinosaur, the sister taxon to the Genasauria. Recent phylogenetic analyses, however, have placed Lesothosaurus as a more derived ornithischian within the Genasauria. The Fabrosauridae, of which Lesothosaurus was considered a member, has never been phylogenetically corroborated and has been considered a paraphyletic assemblage. Prior to recent phylogenetic analyses, the problematic Heterodontosauridae was placed within the Ornithopoda as the sister taxon to the Euornithopoda. The heterodontosaurids have also been considered as the basal member of the Cerapoda (Ornithopoda + Marginocephalia), the sister taxon to the Marginocephalia, and as the sister taxon to the Genasauria. To reevaluate the placement of these taxa, along with other basal ornithischians and more derived subclades, a phylogenetic analysis of 19 taxonomic units, including two outgroup taxa, was performed. Analysis of 97 characters and their associated character states culled, modified, and/or rescored from published literature based on published descriptions, produced four most parsimonious trees. Consistency and retention indices were calculated and a bootstrap analysis was performed to determine the relative support for the resultant phylogeny. The Ornithischia was recovered with Pisanosaurus as its basalmost member. -

From the Late Cretaceous (Campanian) Kanguk Formation of Axel Heiberg Island, Nunavut, Canada, and Its Ecological and Geographical Implications MATTHEW J
ARCTIC VOL. 67, NO. 1 (MARCH 2014) P. 1 – 9 A Hadrosaurid (Dinosauria: Ornithischia) from the Late Cretaceous (Campanian) Kanguk Formation of Axel Heiberg Island, Nunavut, Canada, and Its Ecological and Geographical Implications MATTHEW J. VAVREK,1 LEN V. HILLS2 and PHILIP J. CURRIE3 (Received 1 October 2012; accepted in revised form 30 May 2013) ABSTRACT. A hadrosaurid vertebra was recovered during a palynological survey of the Upper Cretaceous Kanguk Formation in the eastern Canadian Arctic. This vertebra represents the farthest north record of any non-avian dinosaur to date. Although highly abraded, the fossil nonetheless represents an interesting biogeographic data point. During the Campanian, when this vertebra was deposited, the eastern Canadian Arctic was likely isolated both from western North America by the Western Interior Seaway and from more southern regions of eastern North America by the Hudson Seaway. This fossil suggests that large-bodied hadrosaurid dinosaurs may have inhabited a large polar insular landmass during the Late Cretaceous, where they would have lived year-round, unable to migrate to more southern regions during winters. It is possible that the resident herbivorous dinosaurs could have fed on non-deciduous conifers, as well as other woody twigs and stems, during the long, dark winter months when most deciduous plant species had lost their leaves. Key words: Appalachia, Arctic, Campanian, dinosaur, Laramidia, palaeobiogeography RÉSUMÉ. La vertèbre d’un hadrosauridé a été retrouvée pendant l’étude palynologique de la formation Kanguk remontant au Crétacé supérieur, dans l’est de l’Arctique canadien. Il s’agit de la vertèbre appartenant à un dinosaure non avien qui a été recueillie la plus au nord jusqu’à maintenant. -
Defining the Mesozoic
DEBRA LINDSAY THE MESOZOIC/DEFINING DISCIPLINES: LATE NINETEENTH- CENTURY DEBATES OVER THE JURASSIC–CRETACEOUS BOUNDARY DEBRA LINDSAY Department of History and Politics University of New Brunswick, Saint John, NB, Canada E2L 4L5 [email protected] ABSTRACT The last two decades of the nineteenth century were exciting times in American paleontology, with disputes over Jurassic dinosaurs between Edward Drinker Cope and Othniel Charles Marsh appearing in the press. Less well known is the dispute over defining the Mesozoic that began in 1888 when Marsh invited Lester Frank Ward, a colleague with whom he had been working on the Potomac Formation for the United States Geological Survey, to speak on the plant fossils found there. Initially agreeing with Marsh that the Potomac was a Jurassic formation, work on fossil cycads led Ward to conclude that the Potomac was Lower Cretaceous. As Ward and Marsh grappled with the question of how to determine the age and identity of Mesozoic systems, they joined other paleontologists and Earth Sciences History geologists such as William J. McGee, Albert Charles Seward, and Samuel W. Williston in 2011, Vol. 30, No. 2 a debate that often reflected scientific training and sub-specializations as much as pp. 216–239 stratigraphic principles, becoming caught up in a trans-Atlantic dispute in which their reputations were on the line as they claimed that ‘their’ fossils were key determinants of Mesozoic systems. In the end, Marsh’s reputation as a paleontologist was far better established than that of Ward, who moved on to another career as a sociologist at Brown University, but cycad discoveries from Maryland, Colorado and Wyoming, and fieldwork, trumped laboratory studies—even when performed by a master systematist—as the Potomac Formation proved to be Lower Cretaceous. -

Body-Size Evolution in the Dinosauria
8 Body-Size Evolution in the Dinosauria Matthew T. Carrano Introduction The evolution of body size and its influence on organismal biology have received scientific attention since the earliest decades of evolutionary study (e.g., Cope, 1887, 1896; Thompson, 1917). Both paleontologists and neontologists have attempted to determine correlations between body size and numerous aspects of life history, with the ultimate goal of docu- menting both the predictive and causal connections involved (LaBarbera, 1986, 1989). These studies have generated an appreciation for the thor- oughgoing interrelationships between body size and nearly every sig- nificant facet of organismal biology, including metabolism (Lindstedt & Calder, 1981; Schmidt-Nielsen, 1984; McNab, 1989), population ecology (Damuth, 1981; Juanes, 1986; Gittleman & Purvis, 1998), locomotion (Mc- Mahon, 1975; Biewener, 1989; Alexander, 1996), and reproduction (Alex- ander, 1996). An enduring focus of these studies has been Cope’s Rule, the notion that body size tends to increase over time within lineages (Kurtén, 1953; Stanley, 1973; Polly, 1998). Such an observation has been made regarding many different clades but has been examined specifically in only a few (MacFadden, 1986; Arnold et al., 1995; Jablonski, 1996, 1997; Trammer & Kaim, 1997, 1999; Alroy, 1998). The discordant results of such analyses have underscored two points: (1) Cope’s Rule does not apply universally to all groups; and (2) even when present, size increases in different clades may reflect very different underlying processes. Thus, the question, “does Cope’s Rule exist?” is better parsed into two questions: “to which groups does Cope’s Rule apply?” and “what process is responsible for it in each?” Several recent works (McShea, 1994, 2000; Jablonski, 1997; Alroy, 1998, 2000a, 2000b) have begun to address these more specific questions, attempting to quantify patterns of body-size evolution in a phylogenetic (rather than strictly temporal) context, as well as developing methods for interpreting the resultant patterns. -
