1.5 to 2 MYA. The Australopithecus (Paranthropus) robustus Skull SK-48 was discovered by Fourie in Swartkrans, South Africa in 1950 and described by R. Broom in 1952.

• Rigorous standards are applied when selecting original specimens to ensure the best representation
• Proprietary, custom blend of polyurethane developed to capture and replicate minute detail

SK-48, formerly called Paranthropus crassidens, greatly increased what is known about australopithecines. The Transvaal cave site where it was found was blasted by explosives but, remarkably, the skull survived. The skull was found with the right canine, the first premolar and all three molars intact. On the basis of the adult teeth and small sagittal crest, Broom determined the specimen to be an adult female.

The Bone Clones® Hominid line is composed of discoveries from anatomically modern humans, archaic humans, early Homo, early hominins, and other hominids. The majority of the casts in this line have been recreated by a team of anatomical sculptors. Some are reconstructions made by anthropology professionals using fragmentary elements from original discoveries and extrapolating the missing parts from those.
