The first specimen to be found was TM 1517, a partial skeleton with cranial remains from Kromdraai, presently in the Cradle of Humankind World Heritage Site. ''Paranthropus robustus'' and ''boisei'' are known as ''robust australopithecines'', because their skulls in particular are more heavily built. The first fossil representing this species was found in 1955, but it wasn't until the 1959 discovery by Mary Leakey that P. boisei was identified as a new species of hominin.

Category: Paranthropus boisei . Increase of about 2 over comparably sized apes; Australopithecus robustus. 500cc. Cranial capacity in this species suggests a slight rise in brain size (about 100 cc in 1 million years) independent of brain enlargement in the genus Homo. lack of cranial remains makes estimates difficult, but the similarities in jaw and teeth features to other australopithecines, suggest the brain would be in the same size range, 400-550 cubic centimetres, as other species in this genus. This species was probably similar in size to modern chimpanzees. Fossils from more than 100 individuals have been recovered in the last 55 years.
