Stock photography, photos: Early Man - Olduvai Gorge Stock photos of Olduvai Gorge - 3.5 Million year old hominid remains. Footprints at Laetoli left by hominids shorter than ourselves (1.2 to 1.4 metres high). They may have looked more than apes than people, but they walked on two legs. A large, a medium-sized and a small individual walked together, the medium-sized one, stepping in the tracks of its large companion. A day or two later, a fresh ash-fall buried the tracks, until they were excavated in 1978. We know from contemporary fossils that these footprints were made by Australopithecus afarensis, an early hominid. Olduvai Gorge ˆ Laetoli in Tanzania, East Africa.
