The Pennsylvania State University The Graduate School Department of the Geosciences TAXONOMIC AND ECOLOGIC IMPLICATIONS OF MAMMOTH MOLAR MORPHOLOGY AS MEASURED VIA COMPUTED TOMOGRAPHY A Thesis in Geosciences by Gregory J Smith 2015 Gregory J Smith Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science August 2015 ii The thesis of Gregory J Smith was reviewed and approved* by the following: Russell W. Graham EMS Museum Director and Professor of the Geosciences Thesis Advisor Mark Patzkowsky Professor of the Geosciences Eric Post Director of the Polar Center and Professor of Biology Timothy Ryan Associate Professor of Anthropology and Information Sciences and Technology Michael Arthur Professor of the Geosciences Interim Associate Head for Graduate Programs and Research *Signatures are on file in the Graduate School iii ABSTRACT Two Late Pleistocene species of Mammuthus, M. columbi and M. primigenius, prove difficult to identify on the basis of their third molar (M3) morphology alone due to the effects of dental wear. A newly-erupted, relatively unworn M3 exhibits drastically different characters than that tooth would after a lifetime of wear. On a highly-worn molar, the lophs that comprise the occlusal surface are more broadly spaced and the enamel ridges thicken in comparison to these respective characters on an unworn molar. Since Mammuthus taxonomy depends on the lamellar frequency (# of lophs/decimeter of occlusal surface) and enamel thickness of the third molar, given the effects of wear it becomes apparent that these taxonomic characters are variable throughout the tooth’s life. Therefore, employing static taxonomic identifications that are based on dynamic attributes is a fundamentally flawed practice. -

Současný pohled na evoluci chobotnatců Současná systematika chobotnatců není kompletně odvozena od jejich fylogeneze, rekonstruované pomocí kladistických metod. Diskutované skupiny tak mnohdy nepředstavují monofyletické skupiny. Přestože jsou taxonomické kategorie matoucí (např. Laurin 2005), jsem do jisté míry nucen je používat. Některým skupinám úrovně stále přiřazeny nebyly a zde této skutečnosti není přisuzován žádný význam. V této rešerši jsem se zaměřil hlavně na poznatky, které následovaly po vydání knihy; The Proboscidea: Evolution and Paleoecology of Elephants and Their Relatives, od Shoshaniho a Tassyho (1996). Chobotnatci jsou součástí skupiny Tethytheria společně s anthracobunidy, sirénami a desmostylidy (Shoshani 1998; Shoshani & Tassy 1996; 2005; Gheerbrant & Tassy 2009). Základní klasifikace sestává ze dvou skupin. Ze skupiny Plesielephantiformes, do které patří čeledě Numidotheriidae, Barytheriidae a Deinotheridae a ze skupiny Elephantiformes, do které patří čeledě Palaeomastodontidae, Phiomiidae, Mammutida, Gomphotheriidae, tetralofodontní gomfotéria, Stegodontidae a Elephantidae (Shoshani & Marchant 2001; Shoshani & Tassy 2005; Gheerbrant & Tassy 2009). -

Cour. Forsch.-Inst. Senckenberg 256 43–56 4 Figs, 2 Tabs Frankfurt a. M., 15. 11. 2006 Neogene Rhinoceroses of the Linxia Basin (Gansu, China) With 4 fi gs, 2 tabs Tao DENG Abstract Ten genera and thirteen species are recognized among the rhinocerotid remains from the Miocene and Pliocene deposits of the Linxia Basin in Gansu, China. Chilotherium anderssoni is reported for the fi rst time in the Linxia Basin, while Aprotodon sp. is found for the fi rst time in Lower Miocene deposits of the basin. The Late Miocene corresponds to a period of highest diversity with eight species, accompanying very abundant macromammals of the Hipparion fauna. Chilotherium wimani is absolutely dominant in number and present in all sites of MN 10–11 age. Compared with other regions in Eurasia and other ages, elasmotheres are more diversifi ed in the Linxia Basin during the Late Miocene. Coelodonta nihowanensis in the Linxia Basin indicates the known earliest appearance of the woolly rhino. The distribution of the Neogene rhinocerotids in the Linxia Basin can be correlated with paleoclimatic changes.

A review of studies of sexual dimorphism in the vertebrate fossil record revealed methods that were selected for use in ceratopsids. Mountain goats, bison, and pronghorn were selected as exemplar taxa for a proof of principle study that tested the selected methods, and informed and guided the investigation of sexual dimorphism in dinosaurs. Skulls of these exemplar taxa were measured in museum collections, and methods of analysing morphological variation were tested for their ability to demonstrate sexual dimorphism in their horns and horncores. -

Paleoecological Comparison Between Late Miocene Localities of China and Greece Based on Hipparion Faunas
Paleoecological comparison between late Miocene localities of China and Greece based on Hipparion faunas Tao DENG Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing 100044 (China) [email protected] Deng T. 2006. — Paleoecological comparison between late Miocene localities of China and Greece based on Hipparion faunas. Geodiversitas 28 (3) : 499-516. ABSTRACT Both China and Greece have abundant fossils of the late Miocene Hipparion fauna. Th e habitat of the Hipparion fauna in Greece was a sclerophyllous ever- green woodland. Th e Chinese late Miocene Hipparion fauna is represented respectively in the Guonigou fauna (MN 9), the Dashengou fauna (MN 10), and the Yangjiashan fauna (MN 11) from Linxia, Gansu, and the Baode fauna (MN 12) from Baode, Shanxi. According to the evidence from lithology, carbon isotopes, paleobotany, taxonomic framework, mammalian diversity and faunal similarity, the paleoenvironment of the Hipparion fauna in China was a subarid open steppe, which is diff erent from that of Greece. Th e red clay bearing the Hipparion fauna in China is windblown in origin, i.e. eolian deposits. Stable carbon isotopes from tooth enamel and paleosols indicate that C3 plants domi- nated the vegetation during the late Miocene in China. Pollens of xerophilous and sub-xerophilous grasses show a signal of steppe or dry grassland. Forest mammals, such as primates and chalicotheres, are absent or scarce, but grass- land mammals, such as horses and rhinoceroses, are abundant in the Chinese Hipparion fauna. Th e species richness of China and Greece exhibits a similar KEY WORDS trend with a clear increase from MN 9 to MN 12, but the two regions have Hipparion fauna, low similarities at the species level. -

Gomphotheres (Proboscidea, Mammalia) from the Early-Middle Miocene of Central Mongolia by Ursula B. GÖHLICH1 (With 1 text-figure, 3 tables and 1 plate) Manuscript submitted on August 31st 2005, the revised manuscript on January 26th 2006 Abstract Presented here is new fossil proboscidean material from the Miocene Loh Formation of the Valley of Lakes in Central Mongolia. Two, possibly three, different taxa of gomphotheres s. l. are represented in three different localities, but the fragmentary preservation of the couple of cheek teeth and some post- cranial bone remains restricts their systematic determination. Only one molar can be identified as cf. Gomphotherium mongoliense representing the crown morphology of the bunodont type of the "Gompho- therium angustidens group". The residual tooth and remains might belong to more derived, trilophodont gomphotheres of the genus Gomphotherium, or perhaps also to shovel-tusked gomphotheres. Key words: Mongolia, Loh Formation, Miocene, Proboscidea, Gomphotheriidae, Gomphotherium. Zusammenfassung Diese Arbeit stellt neues Material fossiler Proboscidea aus der miozänen Loh Formation aus dem "Tal der Seen" in der Zentral-Mongolei vor.
