A New Species of Teleoceras from the Late Miocene Gray Fossil Site, with Comparisons to Other North American Hemphillian Species
… of a browsing <em>Teleoceras</em> and, as a late Hemphillian locality, represents one of the youngest populations. Linear measurements of post-cranial elements indicate proportional differences between <em>Teleoceras</em> from the Gray Fossil Site and those from other Hemphillian localities. These …

Fossil Trachemys (Testudines: Emydidae) from the Late Hemphillian of Eastern Tennessee and Its Implications for the Evolution of the Emydidae
<p><em>Trachemys</em> (Testudines: Emydidae) represents one of the most well-known turtles today. The evolution of <em>Trachemys</em>, while being heavily documented with various fossil representatives, is not well understood. Numerous fossils from the Gray Fossil Site in northeastern Tennessee are …

Biochronology and magnetostratigraphy of the Pliocene Panaca Formation, southeast Nevada
… Nevadomys was probably derived from the Hemphillian Paramicrotoscoptes. Repomys minor n. sp. is another new species of high-crowned cricetid that was detected in the Panaca local fauna. With abundant upper and lower third molars of Repomys, it was possible to amend the diagnoses of genus …

Systematics, Climate, and Ecology of Fossil and Extant Nyssa (Nyssaceae, Cornales) and Implications of Nyssa grayensis sp. nov. from the Gray Fossil Site, Northeast Tennessee
<p>The Late Hemphillian (latest Miocene or earliest Pliocene, 7-4.5 Ma) Gray Fossil Site in northeastern Tennessee is interpreted to represent a lacustrine paleokarst fed by a river or stream. This research focuses on the morphological and systematic relations of Nyssa endocarps (fruit pits) from …

Miocene herpetofaunas from the central Gulf Coast USA: their paleoecology, biogeography, and biostratigraphy
The late Barstovian Fort Polk herpetofauna represents the most diverse herpetofauna on the Gulf Coast, USA, and includes 15 genera from ten families. The herpetofaunal composition of Fort Polk and Miocene east Texas localities is similar enough to Great Plains localities that they are all …

Non-Ranid Anurans of the Mio-Pliocene Gray Fossil Site, Tennessee
<p>Researchers at the GFS, Washington County, Tennessee through the wet screening of nearly 100%of the sediment excavated at the site, recovered an extensive collection of anuran fossil elements. Until recently, these specimens have not been analyzed. The purpose here is the examination, …
