Paranthropus robustus (or Australopithecus robustus) is an early hominin, originally discovered in Southern Africa in 1938. Particularly regarding cranial features, the development of P. robustus seemed to be in the direction of a "heavy-chewing complex". On account of the definitive traits associated with this "robust" line of australopithecine, anthropologist Robert Broom established the genus Paranthropus and placed this species in it.
