Australopithecus robustus or Paranthropus robustus

Robert Broom first discovered it in 1938 in South Africa. robustus had a body similar to that of Robustus along boisei - University of Minnesotaafricanus, but a larger and more robust skull and teeth. It existed between 2 and 1.5 million years ago. The massive face is a flat or dished, with no forehead and large brow ridge. It has relatively small front teeth, but massive grinding teeth in a large lower jaw. Most specimens have sagittal crests. Its diet would have been mostly coarse, tough food that needed a lot of chewing. The average brain size is about 530 cc. Cranium is still very small and chimp-like. Bones excavated with robustus skeletons indicate that they may have been used as digging tools.

TM 1517, Australopithecus robustus (was Paranthropus robustus)

Discovered by a schoolboy, Gert Terblanche, in 1938 at Kromdraai in South Africa (Broom 1938). It consisted of skull fragments, including five teeth, and a few skeletal fragments. This was the first specimen of robustus.

SK 48, Australopithecus robustus (was Paranthropus crassidens)

Discovered by Mr. Fourie in 1950at Swartkrans in South Africa (Johanson and Edgar 1996). It is a cranium, probably belonging to an adult female, and 1.5-2.0 million years old. It is the most complete skull of robustus.
