Speaking of human remains, Ian Tattersall (who knows a bit about these things) estimates than only one out a billion bones is ever fossilized. Seven billion humans with 206 bones each is a little less than a trillion and a half bones. If Tattersall's estimate is even close to being right, we could expect that all humans currently alive would be fossilized into seven complete skeletons. And this is the best case scenario.
So the South Africa find is a real trove.
