Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. S. Morgan and N. J. Czaplewski 2023 | The m1/m2 are nyctalodont, the talonid is much broader than the trigonid, the talonid is also longer than the trigonid because of the anteroposterior compression of the trigonid, the paraconid and metaconid are close together along the lingual margin, the metaconid is anterior to the protoconid, the protocristid trends anterolingually from the protoconid to the metaconid, the paracristid is gently curved, the paraconid, metaconid, and entoconid are conical with rounded apices and vertically oriented, the protoconid and hypoconid are larger than the lingual cusps with sharply pointed apices, and the hypoconulid is rather large. The m3 has the trigonid broader than the talonid, the paraconid and metaconid are located close to one another along the lingual margin but both cusps are more posterior than on m1/m2, the paracristid and protocristid meet at a more acute angle than on m1/m2, the protoconid and metaconid are located at the same level and the protocristid is at a right angle to the long axis of tooth. The dentary has a long mandibular symphysis extending posteriorly to the p4 and with a rounded projection ventral to the p2 and p4, a p3 is absent, the anterior alveolus of the m1 is flattened anteroposteriorly, a large elliptical mental foramen is present ventral to the p2, a tiny mental foramen is present on the symphysis ventral to the incisor alveoli, the ascending ramus is upturned dorsally posterior to the toothrow, the coronoid process is short and slender dorsally, the angular process is at the same level as the alveolar margin of the toothrow and flares laterally, the articular process is dorsal to the alveolar margin, and the mandibular foramen is large, ventral to the toothrow, and below the tip of coronoid. The M1 has the parastylar region highly reduced anterior and labial to paracone, a well-developed parastyle is present at the anterolabial termination of the narrow paracingulum, the preparacrista very short and oriented labially, the mesostyle is bulbous and oriented anteriorly, the hypocone is small and not separated from the protocone by a notch, and the talon is squarish and somewhat truncated anteroposteriorly. |
