Leptotragulus

Leptotragulus is an extinct genus of protoceratid, endemic to North America. It lived during the Middle Eocene epoch (Uintan to Chadronian stage) 40.2—33.9 Ma, existing for approximately.

Leptotragulus resembled deer. However, they were more closely related to camelids. In addition to having horns in the more usual place, many protoceratids had additional, rostral horns above the orbital cavity. This genus, as well as many other Leptotragulines, was completely hornlees.
