A summary of the history of exploration at the Sterkfontein Caves in the Cradle of Humankind World Heritage Site

Sterkfontein Caves, near Pretoria, South Africa, are part of the Cradle of Humankind World Heritage Site. The caves have yielded hundreds of hominin fossils recovered over a period spanning more than a century. Exploration of the deposits has occurred in three phases. In the first phase from 1895–1935, fossils of various animals were recovered unsystematically by limestone miners, who noted fossiliferous breccias. The second phase, from 1936–1966, involved teams led by Robert Broom and John Robinson. Broom and Robinson’s excavations recovered many hominin fossils from Members 4 and 5, stone artifacts, and initial mapping of the Sterkfontein deposits. The third phase, 1966 until the present, included excavations led by Philip Tobias, Alun Hughes, Tim Partridge, Ron Clarke, Kathy Kuman, and Dominic Stratford. During this phase, the six members of the Sterkfontein deposits were recognized and characterized, and additional fossils of hominins and other fauna, as well as stone artifacts were recovered. Importantly, extensive analysis of fauna and paleonvironments was conducted. Hominin fossils were also recovered from Member 2. Considerable geochronological work has been done to characterize the complex stratigraphy and dating of these deposits. This chapter reviews the history of fieldwork at Sterkfontein.
