well the papers tell us that stone tool making predates the first humans and the earliest tools of this type are associated with australopithicus which has never been directly connected to the earliest homo species anyway
i'm not really seeing it in this case though...the "chopper" lacks a cutting edge, no percussion points on the platform, no ripples in the flake scar and what would appear to be a pressure flaked retouched edge casts doubts on its origin since pressure flaking doesnt appear in the archeological record till homo erectus and the achulean tool set.
i'm not really seeing any flake scars on the quartzite "scraper".
probably river worn fractures and deposited by the same water flow that carved out the valley they're digging into the hill side of there.
we're seeing a lot of historical first claims coming out of china these days
