 (ôs′trə-lō-pĭth′ĭ-kəs, ô-strā′lō-)
n.
A genus of extinct hominins known from Pliocene and early Pleistocene fossil remains found in Africa, characterized by relatively small brain size and evidence of bipedalism. Several species are known, including A. afarensis, dating from four to three million years ago, of which Lucy is the best-known specimen.

[New Latin Austrālopithēcus, genus name : Latin austrālis, southern (because fossil remains of the genus were first found in South Africa); see austral + Greek pithēkos, ape (of unknown origin).]
