Extinct genus of mammals From Wikipedia, the free encyclopedia
Anthracotherium (from Greek: ἄνθραξ anthrax, 'coal' and Greek: θηρίον therium 'beast')[3] is an extinct genus of artiodactyls characterized by having 44 teeth, with five semi-crescentic cusps on the crowns of the upper molars. The genus ranged from the middle Eocene period until the early Miocene, having a distribution throughout Eurasia.[4] Material subjectively assigned to Anthracotherium from Pakistan suggests the last species died out soon after the start of the Miocene.[1]

The genus typifies the family Anthracotheriidae, if only because it is the most thoroughly studied. In many respects, especially the anatomy of the lower jaw, Anthracotherium, as with the other members of the family, is allied to the hippopotamus, of which it is probably an ancestral form.[4] The Anthracotheres, together with the hippos, are grouped with the cetaceans in the clade Whippomorpha.
The genus name stems from the fact that the holotype and other first specimens were originally obtained from the Paleogene (previously known as "Tertiary")-aged lignite beds of Europe.[4]
The European Anthracotherium magnum was approximately as large as a pygmy hippo (about 2 m long and weighing up to 250 kg), but there were several smaller species and the genus also occurs in Egypt, India and North America.[4][5] Members of the genus Anthracotherium, as well as other members of the family Anthracotheriidae, are known colloquially as anthracotheres.
