 "Australopithecus" species are thought to have eaten mainly fruit, vegetables, and tubers, and perhaps easy to catch animals such as small lizards.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.
