Anthropologists recently found fossils of Paranthropus robustus, also called robust australopithecines, in an excavation site in South Africa. Paranthropus coexisted with human ancestors Homo habilis and Homo erectus as recently as 1.5 million years ago. Some anthropologists had believed that Paranthropus' limited diet caused its extinction, but new evidence from the fossils suggests that Paranthropus had a varied diet that included both hard and soft plants as well as herbivores.
