Evidence: 100 • authority: 72

The Gray Fossil Site is an Early Pliocene assemblage of fossils dating between 4.5 and 4.9 million years old, located near the community of Gray in Washington County, Tennessee, USA. The site was discovered during road construction on Tennessee State Route 75 by the Tennessee Department of Transportation in May 2000, after which local officials decided to preserve the site for research and education. The site became part of East Tennessee State University, and the Gray Fossil Site & Museum was opened on the site in 2007. The ancient habitat of the Gray Fossil Site was a pond formed within a sinkhole surrounded by a warm, wet forest. The fossils found at the site represent the ancient plants…

Tapirus polkensis, the pygmy tapir, is a small prehistoric tapir that lived in North America during the late Miocene and early Pliocene. T. polkensis had an estimated mass of around 125 kg (276 lb), making it smaller than any extant tapir. The Gray Fossil Site in northeast Tennessee is home to the world's largest known fossil assemblage of T. polkensis.

A Fossil-Lagerstätte (German pronunciation: [ˈlaːɡɐˌʃtɛtə] – from Lager 'storage, lair' and Stätte 'place'; pl. Lagerstätten) is a sedimentary deposit that preserves an exceptionally high amount of palaeontological information. Konzentrat-Lagerstätten preserve a high concentration of fossils, while Konservat-Lagerstätten offer exceptional fossil preservation, sometimes including preserved soft tissues. Konservat-Lagerstätten may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus delaying the decomposition of both gross and fine biological features until long after a durable impression was created in the surrounding matrix. Fossil-Lagerstätten span geologi…

The Geiseltal fossil deposit is located in the former lignite district of the Geiseltal south of the city of Halle in Saxony-Anhalt, Germany. It is an important site of now extinct plants and animals from the Middle Eocene period 48 to 41 million years ago. There is evidence that coal was first mined in the Geiseltal in 1698, but the first fossils only came to light by chance at the beginning of the 20th century. Scheduled scientific excavations began in 1925 by the Martin Luther University Halle-Wittenberg. Interrupted by World War II, the investigations can be divided into two research phases. Due to the increasing depletion of the raw material deposits, the excavations gradually came to…

Fossil Butte National Monument is a United States National Monument managed by the National Park Service, located 15 miles (24 km) west of Kemmerer, Wyoming, United States. It centers on an assemblage of Eocene Epoch (56 to 34 million years ago) animal and plant fossils associated with Fossil Lake—the smallest lake of the three great lakes which were then present in what are now Wyoming, Utah, and Colorado. The other two lakes were Lake Gosiute and Lake Uinta. Fossil Butte National Monument was established as a national monument on October 23, 1972. Fossil Butte National Monument preserves the best paleontological record of Cenozoic aquatic communities in North America and possibly the worl…

The occurrence of an abdominal fauna in an articulated tapir (<i>Tapirus polkensis</i>) from the Late Miocene Gray Fossil Site, northeastern Tennessee. Abstract The analysis of samples recovered from the abdominal area of an articulated tapir ( Tapirus polkensis ) from the Late Miocene (4.5–7 million BP) Gray Fossil Site (GFS) revealed a rich palyno‐fauna comprised of about 94% egg/oocyst‐like structures and 6% pollen and other palynomorphs. In addition, a group of 6 hickory nuts ( Carya ) was recovered from the same area suggesting that the samples represent the abdominal contents. The analysis of a sample from immediately outside the tapir produced a sample with 98% pollen and less than 0…
