In 2010, cut marks dating to 3.4 mya on a bovid leg were found at the Dikaka site, which were at first attributed to butchery by A. afarensis, [68] but because the fossil came from a sandstone unit (and were modified by abrasive sand and gravel particles during the fossilisation process), the attribution to butchery is dubious.
The discovery of these footprints settled the issue, proving that the Laetoli hominins were fully bipedal long before the evolution of the modern human brain, and were bipedal close to a million years before the earliest known stone tools were made. [11] The footprints were classified as possibly belonging to Australopithecus afarensis.

AL 129-1 is a fossilized knee joint of the species Australopithecus afarensis. It was discovered in Hadar, Ethiopia by Donald Johanson in November 1973. [2] [3] [4] It is estimated to be 3.4 million years old. [1] Its characteristics include an elliptical Lateral condyle and an oblique femoral shaft like that found in humans, indicating bipedalism.
A new analysis of three-toed fossil footprints that date back more than 210 million years reveals that they were created by bipedal reptiles with feet like a bird’s.
