How did the bones get there? How old are the fossils? What is the significance of discovering them? The bones are so deep inside the cave they were almost inaccessible. The scientist who discovered them hired thin, non-claustrophobic scientists to descend a steep cliff and then climb through a 7-inch wide crack in a cave to collect over 1,000 bones.
