Dicynodon hartzenbergi Broom 1940 (dicynodont)

Osteichthyes - Dicynodontia

The status of Dicynodon hartzenbergi is regarded as "uncertain" by Kammerer et al., 2011: "TM 1480 is likely to represent a juvenile geikiid of some kind, but whether it is a pathological tuskless Aulacephalodon, an early range extension of Pelanomodon, or a distinct taxon remains to be determined. A further complication is the existence of small, Pelanomodon-like skulls with extremely narrow intertemporal bars (e.g., RC 44, the holotype of Dicynodon sidneyi) that suggest intertemporal bar width may increase with size in the group. Further research on geikiine ontogeny is required to resolve the identification of these specimens"
