Diagnosis
ReferenceDiagnosis
C. F. Kammerer et al. 2011A very large Permian dicynodontoid characterized by the following unique combination of characters: a steeply angled, sloping snout, anteroposteriorly short premaxilla with weakly ‘hooked’ tip, ventrally directed caniniform process, ru- gose orbital rim, squamosal with broadly rounded dorsal margin in lateral view, postfrontals exposed as thin, strap-like bones at the anteromedian edges of the postorbitals, extremely long, nar- row intertemporal bar with extremely narrow or no median ex- posure of parietals, and vertical orientation of the postorbitals in the intertemporal bar.
