The holotype specimen, OH 5, was discovered by palaeoanthropologist Mary Leakey in 1959, and described by her husband Louis a month later. Two general types are recognized, those with lighter (gracile) bone structure, assigned to the genus Australopithecus, and those with a sturdier (robust) build, assigned to the genus Paranthropus (the members of Paranthropus are sometimes treated as also belonging Australopithecus). Supra-orbital Ridge: Mark it as a ‘C’ or ‘D’, continuous or discontinuous.
