Poabromylus is a small extinct genus of Artiodactyla, of the family Protoceratidae, endemic to North America from the Eocene epoch (Uintan to Chadronian stage) 46.2—33.9 Ma, existing for approximately 12.3 million years.[1]
Taxonomy
Poabromylus was named by Peterson (1931). Its type is Poabromylus kayi. It was assigned to Protoceratidae by Peterson (1931), Carroll (1988), Prothero (1998) and Prothero and Ludtke (2007).[2][3][4][5]
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.
Body mass
Three fossil specimens of Poabromylus were measured by M. Mendoza, C. M. Janis, and P. Palmqvist for body mass.[6] The specimens were determined to weigh:

- Specimen 2: Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value).
- Specimen 3: Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value).
