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 at far top belong to an hipparion,an extinct three-toed horse | |
