cheekbones, a rounded forward projecting nasal bones, an obvious supratoral sulcus, and a moderate constriction of the cranium behind the eye socket. These features contrast with those of the average robust australopithecine. SK 847 also has a short palate and a small temporomandibular joint that could only fit a small, short lower jaw and not the typically massive mandible of a robust australopithecine.

Swartkrans were of the same species and SK 847 is simply a small robust australopithecine. However, the single species
