Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. Ruiz-Ramoni et al. 2022 | Large-sized canid (Fig. 3 and Table S2); premolars with acute cusps; m1 entoconid and hypoconulid are significantly reduced (nearly absent), as in Protocyon. The m1 metaconid is present, unlike P. troglodytes, P. scagliorum, and P. tarijensis, and the hemimandible is more gracile than in those canids. The specimen differs from Canis-Aenocyon in the absence of a transverse crest in the m1 talonid that connects the metaconid to the hypoconid. The specimen differs from Chrysocyon and Theriodictis in less development of the m1 entoconid and hypoconulid. |
