The oldest fossilised jaw bone of early humans dating to about 2.78 million years ago was also found near the site five years ago.Ī team has been working ever since to find out if there is a connection with the origins of systematic stone tool manufacture.
The tools were dug up at a site known as Bokol Dora 1 or BD 1 in the Afar region of north-eastern Ethiopia alongside animal bones of antelopes, prehistoric elephants, primitive hippos, crocodiles and fish.
