Australopithecus africanus (3 to 2 million years ago)
Species Description:
Australopithecus africanus was nearly identical in body
and brain size to A. afarensis. Like A. afarensis, A. africanus
also showed marked differences in size between males and females. Although the teeth
and jaws of A. africanus were much larger than modern human teeth, they are
still more similar to ours than to the teeth of apes. The upper and lower jaws of
A. africanus were also fully rounded in front, like those of modern humans,
and their canine teeth were smaller on average than those of A. afarensis.
Australopithecus africanus individuals probably inhabited open woodlands,
where they would have foraged for fruits, seeds, and roots.

Taung Child
Estimated age: 3 to 2 million years
Date of discovery: 1924
Location: Taung, South Africa
Collected by workers in a lime quarry, this was the first
Australopithecus fossil ever discovered. The scientific community
initially rejected the identification of this partial skull, saying that it
was some sort of extinct ape species rather than an early form of hominid. |

STS 14
Estimated age: 3 to 2 million years
Date of discovery: 1947
Location: Sterkfontein, South Africa
These remains of a small adult female include a nearly
complete vertebral column, a pelvis, some rib fragments, and part of a femur.
The pelvis is far more humanlike than apelike and is strong evidence that
A. africanus was bipedal. |
