Homo habilis
The few "Australopithecus boisei" remains, which include the skull, a thigh bone fragment, and several teeth, were found distributed throughout Beds I and II, which dates them in the range 1.1 to 2 mya. The more common remains of "Homo habilis" were found in Bed I and the lower portion of Bed II, which makes them contemporaries of "Australopithecus boisei". "Homo erectus" remains were found in the upper portions of Bed II, making them contemporaries of "Australopithecus boisei", but not of "Homo habilis".
