The DNH 7 Paranthropus robustus skull from DMQ, the most complete skull of this species ever discovered and a rare female example.

The Drimolen Palaeocave System consists of a series of a terminal Pliocene to early Pleistocene hominin-bearing palaeocave fills[1] located around 40 kilometres (25 mi) north of Johannesburg, South Africa, and about 6 kilometres (3.7 mi) north of Sterkfontein in the UNESCO World Heritage Site Cradle of Humankind.[2]

History of Research[edit]

The site was discovered on 9 July 1992 by Dr Andre Keyser and he continued to direct excavations at the site until his death in 2010. On 21 October 1994 Dr Keyser discovered the DNH 7 (Eurydice) skull, the most complete Paranthropus robustus skull ever found.[3] It is also considered a rare female skull of P. robustus. DNH 8, a male mandible called "Orpheus" was also discovered at the same time and adjacent to DNH 7.[3] Colin Menter directed research and excavations at the site from 2010 until 2016.[2] Excavations at the site were conducted by technical assistants in the early years and by a number of field schools in the latter years. These include the University of Florence, Italy (Prof Jacopo Moggi-Cecchi; 2006-2012), the University of Victoria, Canada (2011, 2012, 2014), and La Trobe University, Australia (Prof Andy Herries; 2013–present). The permit and excavations at the site were taken over by Stephanie Baker of the University of Johannesburg in 2017 in collaboration with Prof Andy Herries of La Trobe University (& the University of Johannesburg) as part of an Australian Research Council Discovery Project (2017–21). This also involves collaborations with Prof David Strait of Washington University in St Louis, who runs a US based field school at Drimolen every June[4] , as well as researchers from South Africa, Australia, the US and Italy. For many years the site was maintained by Simon Mokobane, but he sadly passed away from cancer in early 2018.

Drimolen Main Quarry (DMQ)[edit]

All the hominin remains have been recovered from the classic area of the site known as the Drimolen Main Quarry (DMQ), and include remains of Paranthropus robustus and early Homo.[5] DMQ has also yielded some of the world's oldest bone tools and some of South Africa's oldest stone tools.[6] It is also the first site in the region to have yielded two species of Dinofelis in the same deposit, Dinofelis cf. barlowi and Dinofelis aff. piveteaui.[7]

Drimolen Makondo (DMK)[edit]

The 2.61 million year old Drimolen Makondo fossil bearing palaeocave in South Africa

In 2013 a new fossil deposit was discovered around 50 metres (160 ft) away from the Main Quarry that is known as the Drimolen Makondo (DMK).[2] DMK has not yielded any hominin remains but has been dated to a much older time period around 2.61 Ma,[2] making it similar in age to sites such as Sterkfontein Member 4 and parts of the Makapansgat Limeworks. While DMQ consists of a single large palaeocavern, DMK consists of a series of interconnecting, low maze-like passages. It is not known how the two caves relate to each other and whether they were once part of the same interconnected cave system, but basal speleothems in each deposit have been dated by uranium-lead to ~2.6 million years ago, the same age as flowstones underlying the Australopithecus africanus bearing Sterkfontein Member 4 and capping the A. africanus bearing Makapansgat Limeworks Member 3 deposits.
