 Early in 1997 two fossil preparators and assistants of Clarke, Stephen Motsumi and Nkwane Molefe, were sent to the Silberberg Grotto to try to find the matching piece of tibia that attached to this fragment.Amazingly, within two days they found the remaining part of the bone protruding from the rock in the lower part of the grotto.Because the bones of both legs were in anatomically correct arrangement, the team speculated that it could be a complete skeleton, which was embedded with the face downward in the limestone.
