Its type is Toromeryx marginensis. It was assigned to Protoceratidae by Wilson (1974), Carroll (1988), Prothero (1998) and Prothero and Ludtke (2007).[2][3][4]MorphologyToromeryx resembled deer. However they were more closely related to camelids. In addition to having horns in the more usual place, protoceratids had additional, rostral horns above the orbital cavity. Toromeryx was smaller than Miocene members of Tylopoda: Paratoceras, Protoceras, and. Pseudoprotoceras. Fossil distributionFossils have been recovered from:
