STS 14

STS 14 is a fossilized pelvis, vertebral column and fragmentary rib and femur of the species Australopithecus africanus. It was discovered at Sterkfontein, South Africa by Robert Broom in 1947.

It is estimated to be 2.6-2.8 million years old.

Its characteristics are a distinctly human-like shape to the pelvic blades unlike any other animal. The shape indicates a type of bipedalism. This find was the first to demonstrate, without a doubt, pre-Homo bipedality.

Some scientists have proposed that STS 14 may have come from the same individual as STS 5.
