Taxonomy

Toromeryx was named by Wilson (1974). 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]

Morphology

Toromeryx 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.
