South African Cave Sites A lesson in Stratigraphy and Interpretation

Location of Sterfontein Cave Site

Sterkfontein Cave Site

Raymond Dart

The Taung Baby

Robert Broom

Vindication - Mrs. Ples

Little Foot

Dart’s Original Hypothesis: the Osteodontokeratic Hypothesis of predatory, cannibalistic australopithecines Literal translation bone, tooth and horn

Where did this come from? Cave sites = Living sites Signs of violence Assemblages included hominid bones and stone artifacts Fauna dominated by Jaws bones, end of long bones, & cranial fragments (teeth)

C. K. Brain Figured out the complex Stratigraphy Found the error in Darts hypothesis Hominids were not living in the caves!!

S. African Cave Formation Karst topography Limestone blocks Dissolution Chamber & entrance shaft Erosion and exposure

Leopard Kills

Carnivore Crunchers Bone assemblages from hyena dens yeild the same proportions of body parts as found in the S. African cave sites. Result of eating the softer parts of the bone
