Description
Trail of hominid footprints fossilized in volcanic ash. This 70 metre trail was found by Mary Leakey's expedition at Laetoli, Tanzania in 1978. It dates from 3.6 million years & shows that hominids had acquired the upright, bipedal, free- striding gait of modern man by this date. The trail probably belongs to Australopithecus afarensis & dates from 3.7 to 3.0 million years ago. The footprints show a well developed arch to the foot & no divergence of the big toe. They are of two adults with possibly a third set belonging to a child who walked in the footsteps of one of the adults. The prints to the far right belong to an hipparion, an extinct three-toed horse.
