The first find of australopithecines was the taung child found by raymond dart in a cave in. Now have abundant evidence of australopithicines from more than a dozen separate localities throughout africa. Australopithicines (1-4 ma) contain a morasse of described species and genera (many of them perhaps synonymous) that can be subdivided into gracile and robust forms, as follows: Includes a. aferensis (4-2. 5 ma), a. africanus (3-2. 5 ma), and some fragmentary forms slightly more than 4 ma. One nearly complete skeleton (lucy, 3. 2 million years old from hadar, ethiopia) Height 1-1. 5m, weight 30-65 kg, 400-500 ml brain. Adult gracile australopithecus height 1-1. 5m, weight 30-65 kg, 400-500 ml brain.
