Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. Pickford 2007 | large suiform with tetracuspidate, bunodont upper molars; deep, beaded lingual cingulum in upper molars, P4 bicuspid, cusps subequal; molar enamel thin, lightly wrinkled to smooth. Anterior accessory cusp (paraconule) in upper molars reduced in size, closely applied to the protocone; anterolingual ridge on metaconule; median valley of upper molars completely open from buccal to lingual; sagittal valley
partly blocked by paraconule, otherwise open from mesial to distal, marked lingual and buccal flare in upper molars. Differential diagnosis: differs from Brachyodus, which is of similar size, by its thinner, smooth to lightly wrinkled upper molar enamel, reduced paraconule, lack of parastyle, mesostyle and metastyle, and marked buccal flare in upper molars. Differs from Hippopotamidae by the presence of an anterolingual ridge on the metaconule, thinner enamel and non-trefoliate morphology of the four main cusps. |
