Hominin lower limb bones from Sterkfontein Caves, South Africa (1998–2003 excavations)

We describe late Pliocene and early Pleistocene hominin fossils from Sterkfontein Caves (South Africa), including two femoral specimens, as well a partial tibia fibula. The are likely assignable to Australopithecus africanus and/or prometheus the morphology of each corroborates previous interpretations hominins at least facultative bipeds.
 Significance:
 
 A recent series papers by our research team describes skeleton nicknamed ‘Little Foot’. Based on its unique skull morphology, R.J. Clarke, skeleton’s discoverer, places it in species prometheus, distinct better-known co-occurring africanus. Here we additional thigh leg that, when considered comparative context, support hypothesis that there was significant (probably interspecific) variation South African postcranial during Pleistocene.
