Diagnosis
Reference | Diagnosis | |
---|---|---|
M. M. Emery et al. 2016 | The rostrum is constricted at P2, as in all species of Diplobunops but unlike Agriochoerus. The P3 differs from D. crassus and D. matthewi in having a mesolin- gual cone that is adjusted posteriorly and in possessing strongly pronounced anterior and posterior styles that give it a heart-shaped appearance. The P4 differs from D. matthewi and D. crassus in having fully separated anterolabial and posterolabial cones, but differs from Agriochoerus in lacking a posterolingual conule. The upper molars differ from other species of Diplobunops and Protoreodon in lacking paraco- nules. The upper molars differ from D. crassus and D. mat- thewi in possessing very large, rounded meso- and metastyles. Unlike in D. crassus, the symphysis of the mandible does not jut anteriorly, and the p1 crown is not bent to labial. The lower molars differ from those of other species of Diplobunops in lacking lingual cingulids and having small metastylids and parastylids. |
