Australopithecus anamensis
Australopithecus anamensis is a species of Australopithecus. The first fossilized specimen of the species, though not recognized as such at the time, was a single arm bone found in Pliocene strata in the Kanapoi region of East Lake Turkana by a Harvard University research team in 1965. The specimen was tentatively assigned at the time to Australopithecus and dated about four million years old. Little additional information was uncovered until 1987, when Canadian archaeologist Allan Morton (with Harvard University's Koobi Fora Field School) discovered fragments of a specimen sticking out of a partially eroded hillside east of Allia Bay, near Lake Turkana, Kenya.
