Antifer
Antifer is an extinct genus of large herbivorous deer of the family Cervidae endemic to South America during the Late Pliocene to Late Pleistocene, living from 3.6 Ma-11,000 years ago and existing for approximately . Cervids first entered the formerly isolated continent of South America during the Pliocene as part of the Great American Interchange.
