Salamanders of the Mio-Pliocene Gray Fossil Site, Washington County, Tennessee.
<p>Screening efforts at the Gray Fossil Site, Washington County, Tennessee, have yielded a unique and diverse salamander fauna for the southern Appalachian Mio-Pliocene; including at least five taxa from three modern families (Ambystomatidae, Plethodontidae, and Salamandridae) supporting the …

Non-Ranid Anurans of the Mio-Pliocene Gray Fossil Site, Tennessee
… 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, description, and identification of all non-ranid anuran (frogsand toads) material using …

<em>Vitis</em> Seeds (Vitaceae) from the Late Neogene Gray Fossil Site, Northeastern Tennessee, USA.
… on the morphometric and systematic studies of fossil vitaceous seeds recently recovered from the Gray Fossil Site (7-4.5 Ma, latest Miocene-earliest Pliocene) northeastern Tennessee. Morphologically, all fossil seeds correspond to the extant subgenus <em>Vitis</em> (genus <em>Vitis</em>) of the …

Extreme Variation in the Sagittal Crest of Tapirus polkensis (Mammalia Perissodactyla) at the Gray Fossil Site Northeastern TN.
<p>The preservation and quantity of fossil tapirs (<em>Tapirus polkensis</em>) from the Gray Fossil Site in northeastern Tennessee provides a unique opportunity for comparison and analysis of skeletal characters. Intraspecifically, modern tapirs show little to no variation in the morphology of the …

Population Structure Based on Age-Class Distribution of <em>Tapirus polkensis</em> from the Gray Fossil Site Tennessee.
… of <em>Tapirus polkensis</em> from the Gray Fossil Site exhibit an excellent level of preservation. Intact skulls collected from the site were arranged in a rough age class system separated into 7 categories based on the teeth present and amount of dental wear. Such an eruption series is …

A New Species of Teleoceras from the Late Miocene Gray Fossil Site, with Comparisons to Other North American Hemphillian Species
… of <em>Teleoceras</em> material from the Gray Fossil Site, Gray, Tennessee is provided. This is the only record 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 …

Using Geographical Information Systems to Investigate Spatial Patterns in Fossils of Tapirus polkenis from the Gray Fossil Site, Washington County, Tennessee
<p>Discovered in 2000, the Gray Fossil Site provides a snapshot of the flora and fauna that lived during late Miocene to early Pliocene time in eastern Tennessee. These fossils occur in sediments consisting of fine-grained clays and sands of lacustrine origin, which were deposited after multiple …

The Occurrence of an Abdominal Fauna in an Articulated Tapir (<em>Tapirus polkensis</em>) Recovered from the Miocene Gray Fossil Site Northeast Tennessee.
… tapir from the Late Miocene (4.5-7 million bp) Gray Fossil Site, revealed a rich palyno-fauna comprised of about 94% egg/oocyst-like structures and 6% pollen and other palynomorphs. In addition, a tight grouping of six hickory nuts (<em>Carya</em>) was recovered from the same area suggesting …

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
… (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 the fossil site to …

Fossil Trachemys (Testudines: Emydidae) from the Late Hemphillian of Eastern Tennessee and Its Implications for the Evolution of the Emydidae
… while being heavily documented with various fossil representatives, is not well understood. Numerous fossils from the Gray Fossil Site in northeastern Tennessee are helping to elucidate the taxon’s evolution. The fossil <em>Trachemys</em> at the Gray Fossil Site represent a new species. A …

Variation in the Modified First Metatarsal of a Large Sample of <em>Tapirus polkensis</em> and the Functional Implications for Ceratomorphs.
<p>The Mio-Pliocene age Gray Fossil Site of northeastern Tennessee has the largest collection of tapir postcranial skeletons in the world. Though representing a single species, a few localized structures show high variability. This paper deals with variation of the first metatarsal, which in tapirs …

Applied palynology: Multidisciplinary case studies from Egypt, Gulf of Mexico and USA
… palynofacies, and geochemical analyses of the Gray Fossil Site, eastern Tennessee suggested the presence of asynchronous sub-basins with variable basin-fill histories. A Paleocene-Eocene age was proposed for the studied section based on palynomorphs. Recorded flora consisted primarily of …
