Megacerops
Extinct genus of mammals
Megacerops (lit. 'great horned face') is an extinct genus of horned brontothere that lived in North America during the Late Eocene, in the Chadronian land mammal age. Megacerops is among the best represented large mammals in the fossil record, known from hundreds of complete skulls and several complete skeletons. As the classic brontothere, Megacerops has enjoyed enduring fame in popular culture, often under various historically used names, such as Brontotherium, Brontops, and Titanotherium.
