Archaeotherium
''Archaeotherium'' ((ギリシア語:αρχαιοθήριον), meaning "ancient beast") is an extinct genus of entelodont artiodactyl endemic to North America during the Eocene and Oligocene epochs (38—24.8 mya), existing for approximately .〔(PaleoBiology Database: ''Archaeotherium'', basic info )〕 ''Archaeotherium'' was about 1.2m tall at the shoulder and around 2m long and weighing around 270 kg.
Although superficially pig-like, ''Archaeotherium'', along with all other entelodonts, was more closely related to anthracotheres, hippopotamuses, and whales. Evidence from the Wyoming Dinosaur Center suggests that the omnivorous ''Archaeotherium'', like many modern predatory mammals, kept caches of food for times when their hunting was less successful.
==Taxonomy==
''Archaeotherium'' was named by Leidy (1850). Its type is ''Archaeotherium mortoni.'' It was synonymized subjectively with ''Entelodon'' by Joseph Leidy (1853) and synonymized subjectively with ''Elotherium'' by Leidy (1857). It was assigned to ''Entelodontidae'' by Leidy (1850), Peterson (1909), Scott (1940), Galbreath (1953), Russell (1980), Carroll (1988) and Effinger (1998).〔O. A. Peterson. 1909.
