Laetoli

▪ anthropological and archaeological site, Tanzania
also spelled  Laetolil 

      site of paleoanthropological excavations in northern Tanzania about 40 km (25 miles) from Olduvai Gorge, another major site.

 Mary Leakey (Leakey, Mary Douglas) and coworkers discovered fossils of Australopithecus afarensis (Australopithecus) at Laetoli in 1974–75, not far from where a group of hominin (of human lineage) fossils had been unearthed in 1938. The fossils found at Laetoli date to a period between 3.76 and 3.46 million years ago (mya). They come from at least 23 individuals and take the form of teeth, jaws, and a fragmentary infant skeleton. In volcanic sediments dated to 3.56 mya are trails of remarkably humanlike footprints along with those of numerous animals. A. afarensis is best known from the Ethiopian site of Hadar, but the footprints at Laetoli are of monumental importance in the record of human evolution. Homo sapiens fossils have also been found at Laetoli in strata dating to about 120,000 years ago.
