From “Early Human Ancestor, Australopithecus Sediba, Fossils Discovered in Rock” (Science Daily, July 12, 2012), we learn,
“We have discovered parts of a jaw and critical aspects of the body including what appear to be a complete femur (thigh bone), ribs, vertebrae and other important limb elements, some never before seen in such completeness in the human fossil record,” says Berger. “This discovery will almost certainly make Karabo the most complete early human ancestor skeleton ever discovered. We are obviously quite excited as it appears that we now have some of the most critical and complete remains of the skeleton, albeit encased in solid rock. It’s a big day for us as a team and for our field as a whole.”
The remains are invisible to the casual observer and are entrenched in a large rock about one metre in diameter. It was discovered almost three years ago, but lay unnoticed in the Wits laboratories until early last month.
Hmmm.
