Fossils challenge dna in the dating game
But the particularly shocking thing is that there isn't other material in this particular chamber that can be used to date these fossils.
That's what leads researchers to believe that these bodies were buried — intentionally placed — in this deep, isolated tomb, 100 meters from the cave's entrance.
One of the first skull fragments was particularly challenging.
It would help reveal the size of the head and the brain of this early human cousin, but getting this fragment up and out without breaking it was daunting.
