Three fossiliferous sites in the Northern Sperrgebiet have yielded remains of Rhinocerotidae. At Langental, where Brachypotherium heinzelini Hooijer was already recorded in 1971 on the basis of a mandible fragment, the presence of this rhinoceros is confirmed thanks to a well preserved magnum, an isolated upper molar and above all by an almost complete series of upper cheek teeth. At Grillental a IVth metacarpal indicates the presence of Chilotheridium pattersoni Hooijer, thereby greatly enlarging the geographic and stratigraphic range of this species, hitherto known from the period 18-11 Ma; two other Rhinocerotidae, one of which is indeterminate, the other most likely Brachypotherium cf heinzelini, occur at the site. At Fiskus three upper premolars attest to the presence of Aceratherium acutirostratum (Deraniyagala), its first discovery in southern Africa, and a poorly preserved pyramidal probably belonging to Brachypotherium heinzelini.
