Base moderately vaulted, no angular deviation between palatinal and basal level (in German literature: orthocran). Choanae at about the same level with Fossa glenoidalis (palate comparatively long). Teeth: dental formula -231-334567 - - - 1 - 2 3 4 5 6 7 Upper incisors very small, the outer ones (dagger-shaped) twice the size of the iimer ones (droplet-shaped), medially separated by wide gap (about four times the width of the incisivi). Anterior premolar very small and caniniform, clearly visible distance to canine tooth; also a diastema to the second premolar. Third upper premolar with tliree cusps, the second one more or less forming a two-cusped transitional form. Molars flat, but all tliree of them with fimctional masticatory surface (dilambdodont crown by top view). Row of teeth in basal view ahnost rectangular; width over canine teeth only slightly narrower than molar width of the palate.
