Laetoli is a site in Tanzania, dated to the Plio-Pleistocene and famous for its hominin footprints, preserved in volcanic ash.

The site of the Laetoli footprints (Site G) is located 45 km south of Olduvai gorge.

Pleistocene fauna and Acheulean artifacts have been found in the Olpiro Beds.

Based on a trachytic tuff which occurs within the beds, the Ngaloba Beds may therefore be dated between 120,000 and 150,000 years BP.

Terry Harrison of New York University, leading to the recovery of more than a dozen new hominin finds, Dated to 3.7 million years ago, they were the oldest known evidence of hominin bipedalism at that time.

Subsequently, older Ardipithecus ramidus fossils were found with features that suggest bipedalism.

The hominins seem to have moved in a leisurely stroll. afarensis fossil skeletons and the spacing of the footprints indicate that the hominins were walking at 1.0 m/s or above, which matches human walking speeds.Further analysis indicated that individual S1 was considerably larger than any of the three individuals from site G.Other prints show the presence of twenty different animal species besides the hominin A.With the footprints there were other discoveries excavated at Laetoli including hominin and animal skeletal remains.Analysis of the footprints and skeletal structure showed clear evidence that bipedalism preceded enlarged brains in hominins.This site is called site S, and the 2 individuals who made the prints are named S1 and S2.
