Megacerops

Megacerops ('large horn face') is an extinct genus of North American brontothere. All of the species had a pair of blunt horns on their snout (the size varying between species), with the horns of males being much larger than those of the females. This could indicate that they were social animals which butted heads for breeding privileges.

According to 2004, Megacerops includes the species of the genera Menodus, Brontotherium, Brontops, Menops, Ateleodon, and Oreinotherium

A life-sized model of a Megacerops family (a male, female, and juvenile) is displayed at the Canadian Museum of Nature.
