---|---|---|
E. D. Cope 1873 | Thin premolar with large anterior lobe and posterior heel. Median lobes obtuse; three last lobes connected by a low..edge: Enamel slightly rugose | |
P. Edwards 1976 | Stibarus obtusilobus is the smallest of the leptochoerine species, less than two-thirds the size of S. quadricuspis, with a very weakly developed hypocone on the upper molars. The lingual apex of the triangular upper molars is sharper than the lingual apex of S. quadricuspis upper molars. The cingulum is developed only around the anterior end of the lower molars. |
