![]() ![]() KB is the main fossil deposit at the Kromdraai site. KA is located 30 metres (98 ft) to the south of KB. ![]() It consists of two fossil-bearing localities, Kromdraai A (KA) and Kromdraai B (KB). Kromdraai is contained within the Cradle of Humankind and is approximately 2 kilometres (1.2 mi) east of the Sterkfontein fossil site. Kromdraai is a roofless dolomite cave on the southern side of Blaauwbank stream. Kromdraai B is dated to between approximately 2.0 - 1.6 Ma with the majority if not all the Paranthropus robustus fossils dating to between 1.8 and 1.6 Ma. By 2014, the Kromdraai B fossil assemblages totaled 6,067 specimens. Many thousands of animal fossils have also been recovered from both Kromdraai A and B. robustus, at the time of the writing of this article 29 hominin specimens had been recovered from Kromdraai B. 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.īesides the holotype specimen of P. Thackeray and Berger were later joined by teams from Harvard University and other collaborators. In 1993 excavations were re-opened by Francis Thackeray of the Transvaal Museum and Lee Berger of the University of the Witwatersrand and are currently ongoing. In the 1980s Elizabeth Vrba briefly conducted excavations at Kromdraai B in order to recover additional samples for her work on South African bovids. Brain recommenced work at Kromdraai B and discovered numerous additional hominin remains as well as abundant non-hominin fauna. Two deposits were noted and named at the site - Kromdraai A (KA) and Kromdraai B (KB) - the latter being the site where the hominin remains were recovered. Broom began excavations at the site that would continue until approximately 1947 and would result in the discovery of numerous hominin remains. The teeth formed part of a skull that would become the holotype of Paranthropus robustus. 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. Kromdraai B viewed from the Northeast in 2007
