Kromdraai is a fossil-bearing breccia filled cave located about 2 kilometres (1.2 mi) east of the well known South African hominid-bearing site of Sterkfontein and about 45 km Northwest of the City of Johannesburg, South Africa. It is situated within the Cradle of Humankind World Heritage Site and is itself a South African National Heritage Site.
History of investigations
In 1938, the site was brought to the attention of Robert Broom by a local schoolboy named Gert Terrblanche who had discovered several hominin teeth. The teeth formed part of a skull that would become the holotype of Paranthropus robustus. Broom began excavations at the site that would continue until approximately 1947 and would result in the discovery of numerous hominin remains. Two deposits were noted and named at the site — Kromdraai A and Kromdraai B — the latter being the site where the hominin remains were recovered.
In 1993 excavations were re-opened by Francis Thackeray of the Transvaal Museum and Lee Berger of the University of the Witwatersrand. They were later joined by teams from Harvard University and other collaborators. Important results of this work have been the recovery of additional hominin fossils as well as the obtaining of more accurate dates for the site.
Besides the holotype specimen of P. robustus, at the time of the writing of this article 29 hominin specimens had been recovered from Kromdraai B. Many thousands of animal fossils have also been recovered from both Kromdraai A and B.
