This important discovery was made on the 1^st August 2008 by Lee’s 9 year old son Matthew at a site called Malapa. The series of events leading up to the discovery of the clavicle in a block of breccia thrown off the actual site by a blast by the lime miners has a fascinating human backstory. Had Lee not taken Matthew to the Malapa site that day, the fossils might have lain undiscovered indefinitely. Had Lee not asked Matthew to explore the surrounds with his dog Tau and look for fossils, again these important fossils might have lain undiscovered forever. Had Matthew not chosen to return on the game trail upon which the breccia block containing the clavicle was lying, these homonid fossils would remain lying in their breccia encasement for all time.

This proved to be a very important discovery. Not only did A.sediba prove to be the last in the australopithecine line, dated at 1,97 mybp, but it exhibited a blend of more ancient characteristics (like Lucy) and more modern characteristics like Homo erectus.
