One of the most important archaeological discoveries of the 20th century was documented in the South African Journal of Science on 8 December 1998.
Dr Ron Clark of the palaeo-anthropological research institute of the University of the Witwatersrand discovered the petrified skeleton of a 3,5 million year old hominid (ape-man) in the Sterkfontein Caves near Krugersdorp.
The near-complete skeleton, belonging to the Australopithecus species, is 1.22 metre tall.
Scientists believed the find to be the most significant since the discovery in 1924 of a skull belonging to the so-called Taung child, also in the Sterkfontein caves.
Sterkfontein was declared a World Heritage Site in 2000. The area in which it is situated, was named the Cradle of Humankind.
