Dart, Raymond
Australian-born South African anatomist and anthropologist (1893-1988). In 1924 he described a fossil skull collected near Taung in South Africa, naming it Australopithecus africanus. Dart asserted that the skull was intermediate between the apes and humans, a controversial claim at the time, though later work made it clear that the Taung child, as it came to be known, was indeed a hominid.
