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 ...
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.

Paleontology in Tennessee refers to paleontological research occurring within or conducted by people from the U.S. state of Tennessee. During the early part of the Paleozoic era, Tennessee was covered by a warm, shallow sea. This sea was home to brachiopods, bryozoans, cephalopods, corals, and trilobites. Tennessee is one of the best sources of ...
Washington is the latest state to have found their first dinosaur bone, it was recovered in 2012 but was not publicly identified until May 21, 2015. Some states contain rocks of the appropriate type and age to preserve dinosaur fossils, so the list of states with known dinosaur fossils is likely to increase in the future.
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 ...
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.
Hadrosaur remains have even been found in Iowa, though in fragmentary remains, [64] Tennessee, most notably from the Coon Creek Formation. [ 65 ] [ 66 ] Hypsibema crassicauda , [ 67 ] over fifty feet long, was one of the largest eastern hadrosaurs, outgrowing some of more derived western hadrosaurs like Lambeosaurus and Saurolophus .
The ptersosaur lived roughly 170 million years ago and ruled the skies with a wingspan of more than 8 feet, roughly equivalent to a modern-day albatross.
