The site of important hominid finds and stone artifacts on the northeastern shore of Lake Turkana (formerly Lake Rudolf), in northern Kenya, dating between 2.5 and 1 million years ago. Fragmentary remains of more than 150 hominids, including Australopithecus boisei, A. africanus, and Homo habilis were found. At least two lineages seem to represented in the period between 1 and 1.5 million years ago, Homo erectus and Australopithecus robustus/boisei. Earlier fossils may be of the Homo habilis type. Stone tools are found at several levels from the KBS tuff at about 1.8 million years ago up to some alter levels where had axes appear in small quantities. The large-brained skull numbered 1470, dated to c 2 million years ago, was found here. Richard Leakey worked at the site from 1969.
