Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. M. Hunt 2011 | Largest John Day temnocyo- nine species, m1 length, 28.7 mm, m1 without metaconid thereby distinguished from Tem- nocyon; m1 hypoconid centrally placed on talonid, no entoconid; m1 labial cingulum sinuous, not straight as in Delotrochanter; p4 narrower than in Delotrochanter and Mam- macyon ferocior but similar in this respect to M. obtusidens, T. ferox, and T. macrogenys. Relatively short m2 (E/F ratio, ,1.9, the highest value for any temnocyonine), not
elongate as in Mammacyon, with blunt protoconid and hypoconid the principal cusps, aligned one behind the other along the midline of m2; small m2 paraconid occupies anterointernal corner; no metaconid or entoconid. Mandible deep below m1–2 (43 mm), more so than in any other John Day temnocyonine. |
