TM 1517 is a fossilized skull and lower mandible of the species Paranthropus robustus.It was discovered at Kromdraai, South Africa in 1938 by Robert Broom.. Its characteristics include bony ear tubes positioned below the plane of the cheek bones (more like humans than apes), and a forward set foramen magnum indicating a more erect posture than African apes.
However, that specimen is now formally known as Paranthropus robustus and the earlier name is a junior synonym. Some of these finds were accompanied by evidence of tool use similar to that of Homo erectus; this is why Meganthropus was often linked with that species as H. e. palaeojavanicus.
