Ronald John Clarke is a paleoanthropologist most notable for the discovery of "Little Foot", an extraordinarily complete skeleton of Australopithecus, in the Sterkfontein Caves.

In the late 1970s, Ronald J. Clarke made discoveries of early Hominins in the Swartkrans cave in South Africa.

[6] Ronald J. Clarke and his expedition team explored the Sterkfontein Cave, located 40 kilometers from the capital of South Africa, Johannesburg.

After years of excavating and exploring, in 1994, Clarke made a profound discovery after finding four Australopithecus bones that were joined together.

After this discovery, Clarke and his team excavated the rest of the cave in order to find the missing fragments of "Little Foot".

[7] Ronald J. Clarke excavated the Sterkfontein Cave with two South African anthropologists, Nkwane Molefe and Stephen Motsumi in 1994.
