Ramoceros is an extinct genus of the artiodactyl family Antilocapridae endemic to Middle Miocene (Clarendonian) North America.

[1] Ramoceros is one of several genera that originated from the subfamily Merycodontinae, of which the pronghorn is the only surviving remnant.

[2] In fact, pronghorn is the only surviving remnant of the entire family Antilocapridae.

[4] Ramoceros was a prehistoric relative of modern pronghorn (Antilocapra americana), which is a species of artiodactyl mammal indigenous to interior western and central North America.

[6] The long forked horns of Ramoceros may have been used by rival males in competition.
