Archaeologists in South Africa have unearthed what could be the richest fossil site in Africa.
The Rising Star Expedition uncovered over 1,000 early hominid fossils - a very early form of human being - in a cave an hour north of Johannesburg.
The expedition leader invited the BBC on site to see them at work.
