Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. S. Morgan and N. J. Czaplewski 2023 | The m1 and m2 are nyctalodont, with the talonid significantly broader than the trigonid, paraconid and metaconid very close to one another, metaconid located anterior to the protoconid, postcristid at about a 45° angle to the long axis of tooth, entocristid blade-like and distinctly V-shaped with the apex of V oriented labially, and with a triangular-shaped process that projects posteroventrally from the posterior end of the mandibular symphysis below p4. M1 with a greatly reduced parastylar region, parastyle absent or very small, preparacrista very short, oriented posteriorly and running parallel to the postparacrista, paracingulum well developed, talon triangular in shape with a prominent posterolingual extension, metacingulum with a deep notch just posterior and lingual to the base of the metacone; in the M1 and M2 the talon basin is deeply concave, and in lingual view there is a deep V-shaped notch in the post protocrista separating the protocone and the prominent, triangular hypocone. |
