Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. Z. Barrett 2016 | Sutural contact between the lacrimal and jugal; absence of lateral and medial fossae on the zygomata; zygomata triangular in dorsal view; reduced mastoid with large plate-like paroccipital process; anterior lip of the glenoid socket absent; oblique angle between the braincase, sans sagittal crest, and axial plane of the cranium; posteriorly orientated posterior border of coronoid process; short genial flange, between 22 and 31 % of total dentary length; absence of fossa on ventral face of chin; I3, i1–i3 caniniform; serration density of permanent upper canines per millimeter 2.0–2.7; ratio of height of P3–P4, 0.71 and greater; parastyle absent from P4; P4 protocone well developed with cusp present; M1 transversely elongate, with a prominent protocone widely separated from the paracone, and a posterior extension adjacent to centrocrista, forming a reduced ‘‘t-shape’’; p3 height is as tall or slightly taller than p4; anterior cusp on p4 mesially/distally shorter than the posterior cusp; p4 as tall as or taller than the paraconid of m1; m1 metaconid absent; trigonid proportion of m1 is 77–87%; serrations present on adult minimally worn cheek teeth. |
