Mammalia, Felidae, Canidae, and Mustelidae) from the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas
Chapter 9 Carnivora (Mammalia, Felidae, Canidae, and Mustelidae) From the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas MARGARET SKEELS STEVENS1 AND JAMES BOWIE STEVENS2 ABSTRACT The Screw Bean Local Fauna is the earliest Hemphillian fauna of the southwestern United States. The fossil remains occur in all parts of the informal Banta Shut-in formation, nowhere very fossiliferous. The formation is informally subdivided on the basis of stepwise ®ning and slowing deposition into Lower (least fossiliferous), Middle, and Red clay members, succeeded by the valley-®lling, Bench member (most fossiliferous). Identi®ed Carnivora include: cf. Pseudaelurus sp. and cf. Nimravides catocopis, medium and large extinct cats; Epicyon haydeni, large borophagine dog; Vulpes sp., small fox; cf. Eucyon sp., extinct primitive canine; Buisnictis chisoensis, n. sp., extinct skunk; and Martes sp., marten. B. chisoensis may be allied with Spilogale on the basis of mastoid specialization. Some of the Screw Bean taxa are late survivors of the Clarendonian Chronofauna, which extended through most or all of the early Hemphillian. The early early Hemphillian, late Miocene age attributed to the fauna is based on the Screw Bean assemblage postdating or- eodont and predating North American edentate occurrences, on lack of de®ning Hemphillian taxa, and on stage of evolution.

EURASIAN MIDDLE AND LATE MIOCENE HOMINOID PALEOBIOGEOGRAPHY AND THE GEOGRAPHIC ORIGINS OF THE HOMININAE by Mariam C. Nargolwalla A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Anthropology University of Toronto © Copyright by M. Nargolwalla (2009) Eurasian Middle and Late Miocene Hominoid Paleobiogeography and the Geographic Origins of the Homininae Mariam C. Nargolwalla Doctor of Philosophy Department of Anthropology University of Toronto 2009 Abstract The origin and diversification of great apes and humans is among the most researched and debated series of events in the evolutionary history of the Primates. A fundamental part of understanding these events involves reconstructing paleoenvironmental and paleogeographic patterns in the Eurasian Miocene; a time period and geographic expanse rich in evidence of lineage origins and dispersals of numerous mammalian lineages, including apes. Traditionally, the geographic origin of the African ape and human lineage is considered to have occurred in Africa, however, an alternative hypothesis favouring a Eurasian origin has been proposed. This hypothesis suggests that that after an initial dispersal from Africa to Eurasia at ~17Ma and subsequent radiation from Spain to China, fossil apes disperse back to Africa at least once and found the African ape and human lineage in the late Miocene. The purpose of this study is to test the Eurasian origin hypothesis through the analysis of spatial and temporal patterns of distribution, in situ evolution, interprovincial and intercontinental dispersals of Eurasian terrestrial mammals in response to environmental factors. Using the NOW and Paleobiology databases, together with data collected through survey and excavation of middle and late Miocene vertebrate localities in Hungary and Romania, taphonomic bias and sampling completeness of Eurasian faunas are assessed. -

AMERICAN MUSEUM NOVITATES Published by Tnui AmERMICAN MUSZUM W Number 632 Near York CityRATt1RAL HisToRay June 9, 1933 56.9, 735 G: 14.71, 4 A SKULL AND MANDIBLE OF GIRAFFOKERYX PUNJABIENSIS PILGRIM By EDWIN H. COLBERT The genus Giraffokeryx was founded by Dr. G. E. Pilgrim to desig- nate a primitive Miocene giraffe from the lower Siwalik beds of northern India. Doctor Pilgrim, in a series of papers,' described Giraffokeryx on the basis of fragmental and scattered dentitions.. Naturally, Pilgrim's knowledge of the genus was rather incomplete, and he was unable tQ formulate any opinions as to the structure.of the skull or mandible. An almost complete skull, found in the northern Punjab in 1922 by Mr. Barnum Brown of the American Museum, proves to be that of Giraffokeryx, and it exhibits such striking and unusual characters that a separate description of it has seemed necessary. This skull, together with numerous teeth and a lower. jaw, gives us. a very good comprehen- sion of the genus which forms the subject.of this paper. The drawings of the skull were made by John. C. Germann, and the remaining ones were done by Margaret Matthew. MATERIAL DESCRIBED Only the material referred to in this description will here be listed. There' are a great many specimens of Gir'affokeryx in the American'Mu- seum collection, but since 'most of them are'teeth, they will not be considered at this time. A subsequent paper, dealing with the American Museum Siwalik collection in detail, wtyill contain a complete list of the Giraffokeryx material. -
The Eternal Problem of Homology and Convergence
HYPOTHESES OF HIPPOPOTAMID ORIGINS 31 THE MYTH OF THE HIPPO-LIKE ANTHRACOTHERE: THE ETERNAL PROBLEM OF HOMOLOGY AND CONVERGENCE Martin PICKFORD Collège de France, and Département Histoire de la Terre, UMR 5143 du CNRS, Case postale 38, 57 rue Cuvier, 75005, Paris. e-mail: [email protected] Pickford, M. 2008. The myth of the hippo-like anthracothere: The eternal problem of homology and convergence. [El mito de la similitud entre antracoterios e hipopótamos: el eterno problema entre homología y convergencia.] Revista Española de Paleontología, 23 (1), 31-90. ISSN 0213-6937. ABSTRACT The notion that anthracotheres had hippo-like body proportions, locomotion and lifestyles has been in the lit- erature for so long, and has been repeated so many times, that it has taken on the aura of unquestionable truth. However, right from the beginning of studies into hippo-anthracothere relationships over a century and a half ago, observations were made that revealed the existence of fundamental differences in dental, cranial and post- cranial anatomy in the two groups. From 1836 to 1991 two skeletal characters (a descending plate at the angle of the mandible, and raised orbits) have overshadowed all others in suggesting close relationships between hippos and a single anthracothere genus (Merycopotamus) later to be joined by a second genus, Libycosaurus, in 1991 for the descending angle, and 2003 for the raised orbits (Lihoreau, 2003; Pickford, 1991). Close examination of these structures reveals that they are not homologous in the two groups, yet they have played an inordinately stubborn role in interpretations of the relationships between them, featuring in papers as recently as 2005. -

Khan and 3Abdul Ghaffar 1Zoology department, Quaid-e-Azam campus, Punjab University, Lahore, Punjab, Pakistan 2Zoology Department, GC University, Faisalabad, Punjab, Pakistan 3Department of Meteorology, COMSATS Institute of Information Technology (CIIT), Islamabad ABSTRACT Fossil site Dhok Bun Ameer Khatoon (32o 47' 26.4" N, 72° 55' 35.7" E) yielded a significant amount of mammalian assemblage including two families of even-toed fossil mammal (Giraffidae, and Bovidae) and one family of odd-toed (Rhinocerotidae) of the Late Miocene (Samiullah, 2011). This newly discovered site has well exposed Chinji and Nagri formation and has dated approximately 14.2-9.5 Ma. This age agrees with the divergence of different mammalian genera. Sedimentological evidence of the site supports that this is deposited in locustrine or fluvial environment, as Chinji formation is composed primarily of mud-stone while the Nagri formation is sand dominated. Palaeoenvironmental data indicates that Miocene climate of Pakistan was probably be monsoonal as there is now a days. Mostly the genera recovered from this site resemble with the overlying younger Dhok Pathan formation of the Siwaliks while the size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site to add additional information in the field of Palaeontology. A detailed study of fossils mammals found in Miocene rocks exposed at Dhok Bun Ameer Khatoon was carried out. -
