Dinohyus (meaning "terrible pig") was a large, warthog-like hoofed mammal that lived during the early Miocene, roughly 24 million years ago. This herbivore (it ate plants, including roots) had a long skull (over 1 m = 3 feet long), a small braincase, a pair of knob-like protrusions on the back of the lower jaw (in the cheek area), blunt incisors, and wide, strong canine teeth. Its long legs probably made it a fast runner. The neck was short and stout and there was a hump on the shoulders formed by spines along the backbone. It was about 6 feet (2 m) tall at the shoulders and was the biggest and among the last of the Entelodonts. Fossils have been found in western North America (including Battle Creek, South Dakota, USA). Classification: Class Mammalia (mammals), Order Artiodactyla (even-toed ungulates), Family Entelodontidae (large, pig-like mammals from the Oligocene to early Miocene, including Archaeotherium, Megachoerus, Dinohyus, Entelodon and Eoentelodon), Genus Dinohyus.
