Taxonomy
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).
Morphology
Poabromylus 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. Poabromylus was larger than Eocene members of Tylopoda: Heteromeryx, Leptoreodon, Leptotragulus, Toromeryx, Trigenicus, and Poabromylus.
Body mass
A single fossil specimen of Poabromylus was measured by M. Mendoza, C. M. Janis, and P. Palmqvist for body mass. The specimen was determined to weigh:
