Eporeodon
''Eporeodon'' is an extinct genus of oreodont belonging to the subfamily ''Eporeodontinae'' during the Oligocene epoch (33.3—20.6 mya) existing for approximately .〔(PaleoBiology Database: ''Eporeodon'', basic info )〕 The species of the genus are among the largest members of the family Merycoidontidae. About the size of a cow, its fossils are some of the largest found in the Badlands. It was much larger than ''Merycoidodon'' and ''Miniochoerus'', its contemporaries in the Late Oligocene. On the other hand, ''Eporeodon'' was a rare oreodont, as its fossils only make up about one percent of all oreodont fossils found in the Badlands. ==Taxonomy== ''Eporeodon'' was named by Marsh (1875). It was synonymized subjectively with ''Eucrotaphus'' by Cope (1884). It was assigned to ''Merycoidodontidae'' by Marsh (1875), Scott (1890), Thorpe (1921), Thorpe (1937), Stevens and Stevens (1996) and Lander (1998). It's synonymized with ''Hypselochoerus'' and ''Pseudodesmatochoerus''.〔M. R. Thorpe. 1921. John Day Eporeodons, with descriptions of new genera and species. American Journal of Science〕
