Diagnosis
ReferenceDiagnosis
E. H. Colbert 1938
Large, specialized bunodont artiodactyls. Skull greatly modified, even in the most primitive genera. Basicranium compressed and foramina more or less coalesced, paroccipital processes short but massive, auditory bulla developed. Orbit usually displaced towards the posterior portion of the skull. Dental formula either complete or reduced; molars, upper and lower, four-cusped and elongated. Feet didactyl, but with the metapodials not coalesced.
