Abstract: Isochron burial dating with cosmogenic nuclides 26Al and 10Be shows that the skeleton of the australopithecine individual known as ‘Little Foot’ is around 3.67 million years old, coeval with early Australopithecus from East Africa; a manuport dated to 2.18 million years ago from the Oldowan tool assemblage conforms with the oldest age previously suggested by fauna.
