One of three neighbouring South African sites (the others being Kromdraai and Swartkrans) at which the remains of fossil hominids have been found.

The fossils found include those of Australopithecus africanus, A. robustus (see Australopithecus), and Homo erectus. In 1996 researchers uncovered the most complete australopithecine fossil skeleton since Lucy, that of an A. africanus individual with a humanlike pelvis but with limb proportions similar to those of a modern chimpanzee. At Makapansgat, 150 mi (240 km) to the north, the remains of about 40 individuals of A. africanus have been found.

▪ anthropological and archaeological site, South Africa
 site of paleoanthropological excavations just south of Johannesburg, South Africa, known for its artifacts as well as its fossils of ancient hominins (members of the human lineage). Located in the Highveld, the site was mined throughout the 20th century for its lime deposits. In 1936 Robert Broom of the Transvaal Museum in Pretoria began collecting fossils from the miners. This led to the first discovery of an adult Australopithecus africanus (Australopithecus), an early hominin originally described in 1925 from Taung, another South African site. At first Broom ascribed his fossils to A. transvaalensis, a hitherto-unknown species. In 1947 he uncovered an adult skull so unique and well preserved that he proposed an entirely new genus, Plesianthropus transvaalensis. However, “Mrs. Ples,” as the 1947 fossil came to be known, is now classified with Broom's other finds as A. africanus. Crews continue to work at Sterkfontein, and the site has been one of the richest sources of information about human evolution, yielding more than 500 fossils.

      The site contains six very distinct geologic “members.” From Member 2 comes a beautifully preserved skeleton dating to approximately 3.3 million years ago (mya). In Member 4 (c. 2.7 mya) are the rich remains of A. africanus, with its small—almost ape-sized—brain, humanlike teeth, and intermediate skull. The body of A. africanus is fundamentally human in that it is adapted for walking upright, but it retains long forelimbs and short hindlimbs reminiscent of an ape. In Member 5 (1.5 to 2 mya) occur specimens attributed to Homo habilis as well as possible remains of the “robust” australopith, Paranthropus robustus (Australopithecus). Stone tools are conspicuously absent from levels at Sterkfontein associated with A. africanus (Members 2 and 4), but, during the time of Member 5, tools are abundant.

      Sterkfontein, along with the neighbouring sites of Kromdraai and Swartkrans, are located within the Cradle of Humankind, a region designated a UNESCO World Heritage site in 1999.
