Fossil Skull Collected from South Dakota

​​​​​​​This skull belonged to an oreodont, an extinct North American herbivore that lived during the MiddleEocene through the end of the Miocene epoch-between roughly 40 million and 5.3 million years ago. They looked like a mix between a sheep, a camel, and a pig. They had short faces, fang-like canine teeth in front with molars in the back, heavy bodies, short legs with four-toed hooves, and long tails.
