<P> In a 1979 preliminary microwear study of Australopithecus fossil teeth , anthropologist Alan Walker theorized that robust australopiths were largely frugivorous . Australopithecus species mainly ate fruit , vegetables , small lizards , and tubers . Much research has focused on a comparison between the South African species A. africanus and Paranthropus robustus . Early analyses of dental microwear in these two species showed , compared to P. robustus , A. africanus had fewer microwear features and more scratches as opposed to pits on its molar wear facets . </P>
