The Thomas Farm site is one of the richest terrestrial deposits of Miocene vertebrates in the 18 Ma range found in eastern North America according to the Florida Museum of Natural History.[2] The site was discovered in 1931 by Florida Geological Survey (FGS) staff member Clarence Simpson.[3] Specimens include: amphibians, reptiles, birds, small rodents,[4] bats,[5][6] rhinoceroses, three species of three-toed horses,[7][8] several artiodactyls (including camels, peccary, deer-like species and other extinct forms), as well as dogs, bears, and bear-dogs.[9][10][11][12]
