Members of the genus " Anthracotherium ", as well as other members of the family Anthracotheriidae, are known colloquially as anthracotheres.

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.

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.
A rough evolutionary lineage can be traced from Eocene and Oligocene species : " Anthracotherium " and " Elomeryx " to the Miocene species " Merycopotamus " and " Libycosaurus " and the very latest anthracotheres in the Pliocene . " Merycopotamus ", " Libycosaurus " and all hippopotamids can be considered to form a clade, with " Libycosaurus " being more closely related to hippos.
