A Partial Short-Faced Bear Skeleton from an Ozark Cave with Comments on the Paleobiology of the Species
Blaine W. Schubert and James E. Kaufmann - A partial short-faced bear skeleton from an Ozark cave with comments on the paleobiology of the species. Journal of Cave and Karst Studies 65(2): 101-110. A PARTIAL SHORT-FACED BEAR SKELETON FROM AN OZARK CAVE WITH COMMENTS ON THE PALEOBIOLOGY OF THE SPECIES BLAINE W. SCHUBERT Environmental Dynamics, 113 Ozark Hall, University of Arkansas, Fayetteville, AR 72701, and Geology Section, Research and Collections, Illinois State Museum, Springfield, IL 62703 USA JAMES E. KAUFMANN Department of Geology and Geophysics, University of Missouri-Rolla, Rolla, MO 65409 USA Portions of an extinct giant short-faced bear, Arctodus simus, were recovered from a remote area with- in an Ozark cave, herein named Big Bear Cave. The partially articulated skeleton was found in banded silt and clay sediments near a small entrenched stream. The sediment covered and preserved skeletal ele- ments of low vertical relief (e.g., feet) in articulation. Examination of a thin layer of manganese and clay under and adjacent to some skeletal remains revealed fossilized hair. The manganese in this layer is con- sidered to be a by-product of microorganisms feeding on the bear carcass. Although the skeleton was incomplete, the recovered material represents one of the more complete skeletons for this species. The stage of epiphyseal fusion in the skeleton indicates an osteologically immature individual. The specimen is considered to be a female because measurements of teeth and fused postcranial elements lie at the small end of the size range for A. simus. Like all other bears, the giant short-faced bear is sexually dimorphic. -

Coprolites of Deinosuchus and Other Crocodylians from the Upper Cretaceous of Western Georgia, Usa
Milàn, J., Lucas, S.G., Lockley, M.G. and Spielmann, J.A., eds., 2010, Crocodyle tracks and traces. New Mexico Museum of Natural History and Science, Bulletin 51. 209 COPROLITES OF DEINOSUCHUS AND OTHER CROCODYLIANS FROM THE UPPER CRETACEOUS OF WESTERN GEORGIA, USA SAMANTHA D. HARRELL AND DAVID R. SCHWIMMER Department of Earth and Space Sciences, Columbus State University, Columbus, GA 31907 USA, [email protected] Abstract—Associated with abundant bones, teeth and osteoderms of the giant eusuchian Deinosuchus rugosus are larger concretionary masses of consistent form and composition. It is proposed that these are crocodylian coprolites, and further, based on their size and abundance, that these are coprolites of Deinosuchus. The associated coprolite assemblage also contains additional types that may come from smaller crocodylians, most likely species of the riverine/estuarine genus Borealosuchus, which is represented by bones, osteoderms and teeth in fossil collections from the same site. INTRODUCTION The Upper Cretaceous Blufftown Formation in western Georgia contains a diverse perimarine and marine vertebrate fauna, including many sharks and bony fish (Case and Schwimmer, 1988), mosasaurs, plesio- saurs, turtles (Schwimmer, 1986), dinosaurs (Schwimmer et al., 1993), and of particular interest here, abundant remains of the giant eusuchian crocodylian Deinosuchus rugosus (Schwimmer and Williams, 1996; Schwimmer, 2002). Together with bite traces attributable to Deinosuchus (see Schwimmer, this volume), there are more than 60 coprolites recov- ered from the same formation, including ~30 specimens that appear to be of crocodylian origin. It is proposed here that the larger coprolites are from Deinosuchus, principally because that is the most common large tetrapod in the vertebrate bone assemblage from the same locality, and it is assumed that feces scale to the producer (Chin, 2002). -

Fowler and Kulm (19701, in a predominantly geolgg isal study, used the presence of sublittor31 and planktsnic foraminiferans as an indication of uplift of tfie deep-sea fioor. Their resuits showed tiac sedinenta ana foraminiferans are depositea in the Zscanaba Trough, in the southern part of the Corda Ridge, by turbidity currents with a continental origin. They list 22 species of fararniniferans from the Gorda Rise (See Appendix 13. A more recent study collected geophysical, geological, and biological data from the Gorda Ridge, with particular emphasis on the northern part of the Ridge (Clague et al. 19843. Geological data suggest the presence of widespread low-temperature hydrothermal activity along the axf s of the northern two-thirds of the Corda 3idge. However, the relative age of these vents, their present activity and presence of sulfide deposits are currently unknown. The biological data, again with an emphasis on foraminiferans, indicate relatively high species diversity and high density , perhaps assoc iated with widespread hydrotheraal activity. -

Notes on the History of the Paleontological Collection, Department of Geology, Indiana University Alan Stanley Horowitz Department of Geology, Indiana University Bloomington, Indiana 47405 Introduction In the past, paleontologic papers, especially those printed prior to 1930, com- monly did not indicate the repository of the collections on which the published record was based. Workers generally assume the collections reside at the institution to which the author was associated as either student or faculty. Some early workers were not associated with any academic institution, and early collections have been scattered or destroyed. Because inquiries are made frequently to Indiana University concerning both the University and Indiana State Geological Survey collections, this paper provides some general information on earlier collections insofar as is presently known. According to Wylie (36), the records of Indiana University prior to 1883 were largely destroyed by fire. Wylie (36:31) quoted statements concerning geological col- lections from as early as 1852 in legislative acts affecting the University, e.g., "The Lecturers were also to make geological examinations, and collect mineralogical specimens for the cabinet by volunteer donations." No attempt has been made to reconstruct possible paleontological collections, other than the Owen collection, based on any ex- tant University catalogues or Reports of the President of Indiana University published prior to 1883, and I assume that any geological collections or catalogues prior to this date were lost in the 1883 fire reported by Wylie (36:83). The Owen Collection Our knowledge of the Indiana University Department of Geology (IUB) paleon- tological collections begins with the collection of David Dale Owen. -
Quaternary Records of the Dire Wolf, Canis Dirus, in North and South America
Quaternary records of the dire wolf, Canis dirus, in North and South America ROBERT G. DUNDAS Dundas, R. G. 1999 (September): Quaternary records of the dire wolf, Canis dirus, in North and South Ameri- ca. Boreas, Vol. 28, pp. 375–385. Oslo. ISSN 0300-9483. The dire wolf was an important large, late Pleistocene predator in North and South America, well adapted to preying on megaherbivores. Geographically widespread, Canis dirus is reported from 136 localities in North America from Alberta, Canada, southward and from three localities in South America (Muaco, Venezuela; Ta- lara, Peru; and Tarija, Bolivia). The species lived in a variety of environments, from forested mountains to open grasslands and plains ranging in elevation from sea level to 2255 m (7400 feet). Canis dirus is assigned to the Rancholabrean land mammal age of North America and the Lujanian land mammal age of South Amer- ica and was among the many large carnivores and megaherbivores that became extinct in North and South America near the end of the Pleistocene Epoch.

La Brea and Beyond: the Paleontology of Asphalt-Preserved Biotas
La Brea and Beyond: The Paleontology of Asphalt-Preserved Biotas Edited by John M. Harris Natural History Museum of Los Angeles County Science Series 42 September 15, 2015 Cover Illustration: Pit 91 in 1915 An asphaltic bone mass in Pit 91 was discovered and exposed by the Los Angeles County Museum of History, Science and Art in the summer of 1915. The Los Angeles County Museum of Natural History resumed excavation at this site in 1969. Retrieval of the “microfossils” from the asphaltic matrix has yielded a wealth of insect, mollusk, and plant remains, more than doubling the number of species recovered by earlier excavations. Today, the current excavation site is 900 square feet in extent, yielding fossils that range in age from about 15,000 to about 42,000 radiocarbon years.
