Paratoceras is an extinct genus of medium-sized protoceratid endemic to North America from the Miocene epoch, 16.3—15.97 Ma, existing for approximately 0.33 million years.


Paratoceras was named by Frick (1937). Its type is Paratoceras macadamsi. It was assigned to Protoceratidae by Frick (1937) and Carroll (1988); and to Protoceratinae by Webb (1981), Prothero (1998), Webb et al. (2003) and Prothero and Ludtke (2007).


Paratoceras 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. Paratoceras was larger than Eocene members of Tylopoda: Heteromeryx, Leptoreodon, Leptotragulus, Toromeryx, Trigenicus and Poabromylus.

Body massEdit

A single fossil specimen of Paratoceras was measured by M. Mendoza, C. M. Janis, and P. Palmqvist for body mass. The specimen was determined to weigh:

  • Specimen 1: 73.3 kg (160 lb)
