Plesiosaurus (Greek: πλησίος (plesios), near to + σαῦρος (sauros), lizard) is a genus of extinct, large marine sauropterygian reptile that lived during the Early Jurassic. It is known by nearly complete skeletons from the Lias of England. It is distinguishable by its small head, long and slender neck, broad turtle-like body, a ...
In December 2017, a large skeleton of a plesiosaur was found in the continent of Antarctica, the oldest creature on the continent, and the first of its species in Antarctica. [47] Not only has the number of field discoveries increased, but also, since the 1950s, plesiosaurs have been the subject of more extensive theoretical work.
The Coats–Hines–Litchy site (formerly Coats–Hines) is a paleontological site located in Williamson County, Tennessee, in the Southeastern United States.The site was formerly believed to be archaeological, and identified as one of only a very few locations in Eastern North America containing evidence of Paleoindian hunting of late Pleistocene proboscideans.

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. The site was discovered during road construction on Tennessee State Route 75 by the Tennessee Department of Transportation in May 2000, [1] after which local officials ...
This was the first plesiosaur specimen of this caliber found in all of North America. Dr. Turner gave some of the vertebrae to a member of the Union Pacific railroad survey, John LeConte. He in turn gave the bones to paleontologist Edward Drinker Cope, who identified them as the remains of a very large plesiosaur. Cope wrote a letter to Dr ...
Fossils that may have belonged to the holotype were found by the American geologist Benjamin Franklin Mudge in 1871, but have probably been lost since. [3] Additional plesiosaur fossils were recovered near the original locality in 1954, 1991, 1994, and 1998, including back vertebrae, ribs, gastralia (belly ribs), and gastroliths. As none of ...
Craighead Caverns is an extensive cave system located in between Sweetwater and Madisonville, Tennessee. It is best known for containing the United States ' largest and the world's second largest non- subglacial underground lake, The Lost Sea. In addition to the lake, the caverns contain an abundance of crystal clusters called anthodites ...
In fact, nothing has been found to show what Kimmerosaurus may have looked like below the neck, although the atlas and the axis are similar to those of the plesiosaur Colymbosaurus. It is this lack of any post- cranial fossils, and the bone similarities that has led to the belief that Kimmerosaurus fossils could be the missing head of ...
