Entelodon ( synonym = "Elotherium"), is a genus of Eurasian entelodont from the early Oligocene, and is the type genus of the family.
Entelodon is a typical entelodont, in that it was a cow-sized bunodont artiodactyl with a large, pig-like head with tremendous teeth and wart-like tubercules on the mandibles. It is one of three entelodont genera native to Eurasia, the other two being the primitive Eoentelodon of late Eocene China and the gigantic Paraentelodon of mid to late Oligocene Central Asia.
