Diagnosis
ReferenceDiagnosis
D. R. Prothero and M. R. Liter 2008Male supraorbital horns long, projecting anteriorly and laterally. Antorbital vacuity and lacrimal fossa present. Nasals elon-
gate, with paired nasal bosses in males, and deep maxillary pits. Unworn molars may retain a weak Palaeomeryx fold. More brachyodont molars than Aletomeryx, metapodials more heavily proportioned (modified from Janis and Manning, 1998, p. 482).
