A Stable Isotopic Investigation of Resource Partitioning Among Neosauropod Dinosaurs of the Upper Jurassic Morrison Formation
A stable isotopic investigation of resource partitioning among neosauropod dinosaurs of the Upper Jurassic Morrison Formation Benjamin T. Breeden, III SID: 110305422 [email protected] GEOL394H University of Maryland, College Park, Department of Geology 29 April 2011 Advisors: Dr. Thomas R. Holtz1, Jr., Dr. Alan Jay Kaufman1, and Dr. Matthew T. Carrano2 1: University of Maryland, College Park, Department of Geology 2: National Museum of Natural History, Department of Paleobiology ABSTRACT For more than a century, morphological studies have been used to attempt to understand the partitioning of resources in the Morrison Fauna, particularly between members of the two major clades of neosauropod (long-necked, megaherbivorous) dinosaurs: Diplodocidae and Macronaria. While it is generally accepted that most macronarians fed 3-5m above the ground, the feeding habits of diplodocids are somewhat more enigmatic; it is not clear whether diplodocids fed higher or lower than macronarians. While many studies exploring sauropod resource portioning have focused on differences in the morphologies of the two groups, few have utilized geochemical evidence. Stable isotope geochemistry has become an increasingly common and reliable means of investigating paleoecological questions, and due to the resistance of tooth enamel to diagenetic alteration, fossil teeth can provide invaluable paleoecological and behavioral data that would be otherwise unobtainable. Studies in the Ituri Rainforest in the Democratic Republic of the Congo, have shown that stable isotope ratios measured in the teeth of herbivores reflect the heights at which these animals fed in the forest due to isotopic variation in plants with height caused by differences in humidity at the forest floor and the top of the forest exposed to the atmosphere. -
Description of the Hollidaysburg and Huntingdon Quadrangles
DESCRIPTION OF THE HOLLIDAYSBURG AND HUNTINGDON QUADRANGLES By Charles Butts INTRODUCTION 1 BLUE RIDGE PROVINCE topography are therefore prominent ridges separated by deep SITUATION The Blue Ridge province, narrow at its north end in valleys, all trending northeastward. The Hollidaysburg and Huntingdon quadrangles are adjoin Virginia and Pennsylvania, is over 60 miles wide in North RELIEF ing areas in the south-central part of Pennsylvania, in Blair, Carolina. It is a rugged region of hills and ridges and deep, The lowest point in the quadrangles is at Huntingdon, Bedford, and Huntingdon Counties. (See fig. 1.) Taken as narrow valleys. The altitude of the higher summits in Vir where the altitude of the river bed is about 610 feet above sea ginia is 3,000 to 5,700 feet, and in western North Carolina 79 level, and the highest point is the southern extremity of Brush Mount Mitchell, 6,711 feet high, is the highest point east of Mountain, north of Hollidaysburg, which is 2,520 feet above the Mississippi River. Throughout its extent this province sea level. The extreme relief is thus 1,910 feet. The Alle stands up conspicuously above the bordering provinces, from gheny Front and Dunning, Short, Loop, Lock, Tussey, Ter each of which it is separated by a steep, broken, rugged front race, and Broadtop Mountains rise boldly 800 to 1,500 feet from 1,000 to 3,000 feet high. In Pennsylvania, however, above the valley bottoms in a distance of 1 to 2 miles and are South Mountain, the northeast end of the Blue Ridge, is less the dominating features of the landscape. -

NEW SPECIES OF SILURIAN FOSSILS FROM THE ED:N'IUNDS AND PEMBROKE FORMATIONS OF WASHINGTON COUNTY, MAINE. By Henry Shaler Williams, Of Cornell University, Ithaca, New Yorh. INTRODUCTION. In preparing the Eastport folio of the United States Geological Survey for pubhcation the more characteristic fossils of the Silurian formations there mapped were selected for illustration. Among them the following were new, and as the folio is an inconvenient place for publishing descriptions of new species, the following paper will describe and illustrate a few of the more common and characteristic new species found in the Edmunds and Pembroke formations of Washington County, Maine. The type-specimens of all of these new species are in the collections of the United States National Museum, and the catalogue numbers under which they are registered are indi- cated in the following descriptions. For greater precision the Geo- logical Survey locality numbers and my own numbers given to indi- vidual specimens are also noted wherever necessary. The species from the Edmunds formation are: Whitfieldella edmundsi. Palaeopecten cobscooH. Chonetes edmundsi. Palaeopecten transversalis. Chonetes cobscooki. Tolmaia compestris. Brachyprion shaleri. Pterinea (f Tolmaia) trescotti. The Pembroke species are: Chonetes bastini. Grammysia pembrohensis. Camarotoechia leightoni. Lingula minima var. americana. Actinopteria bella. Modiolopsis leightoni. Actinopteriafornicata. Modiolopsis leightoni var. quodraJta. Actinopteria dispar. Nuculites corrugata. Lingula scobina. Leiopteria rubra. On plate 30, illustrating the Pembroke fauna, are also included figures of Dalmanella lunata (Sowerby), and on plate 31, Eurymyella shaleri var. minor, WiUiams, the type of which was described from the Eastport formation,^ (formation No. V), and figures of Platij- 1 Proc. -

CNIDARIA Corals, Medusae, Hydroids, Myxozoans
FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell. -
Phylum: Mollusca Conus Platyceras
Phylum: Mollusca Phylum: Mollusca Class: Gastropoda Common Name or members: snails, nudibranchs, sea hares and garden slugs Habitat: All habitats: marine, freshwater, terrestrial Periods of Existence: Cambrian to Recent Description: Most Gastropod shells, especially from the Paleozoic, are preserved as internal molds (steinkerns), external molds, or casts. The typical Gastropod shell is “trochospiral” or a spiraled cone shape with a solid spire running through the center, and a aperture or opening. One complete turn of the coil is called a whorl. Gastopod shells contain only a single spiraled chamber – the animal’s body coils up and fills the entire interior of the shell. Conus Cypraea Platyceras Fossils to ID 2016 - Set B.doc 1 of 8 12/4/2015 12:54:00 PM Turritella Worthenia Fossils to ID 2016 - Set B.doc 2 of 8 12/4/2015 12:54:00 PM Phylum: Echinodermata Description: ‘Spiny skinned’ (Greek) marine animals with 5 point radial (pentaradial) symmetry as adults. Echinoderms have an endoskeleton of calcite plates (ossicles), each of which is a single stereom crystal; a water vascular system used for gas exchange, feeding, sensory reception and locomotion; and ambulacral grooves with cilia and hydraulically driven tube feet to manipulate captured food down the grooves to the mouth. Phylum: Echinodermata Class: Asteroidea Common Name or members: sea stars, starfish Habitat: Marine Periods of Existence: Ordovician to Recent Description: Sea stars are radially symmetrical, with arms radiating out from the body center. Most species have five arms, however sun stars can have as many as 40 arms or more! Most sea stars are small usually measuring 12-24 cm across, but there are some species that can be very small or very large.
