Additional Content

The exceptional well-preserved skull of an early man-ape which Robert Broom called Plesianthropus transvaalensis lived about two million years ago. Broom and Robinson concluded that it was the skull of a middleaged female, and since then STS 5 was known as Mrs. Ples: [STS 5] The species has subsequently been reclassified as Australopithecus africanus when the skull was positively recognized as belonging to the same species as the 'ape-child' skull discovered by Professor Raymond Dart at Taung in the northern Cape in 1924.
