 You're confusing yourself.
 Your claim is that hematite is what resulted in chins. That, the
reason why the characterization of so called moderns includes chins
is because of the use of hematite. WHICH REQUIRES that where and
when hematite is not used we will not find people with chins.

You mean, if somebody would accidentally lose something that is valuable? No, you don't accidentally lose something that is valuable. Lets see the very recent example. We had "Iron Age", before that it was "Bronze Age", before that it was "Copper Age". They know when Iron Age started, they do know when Bronze Age started, but they have not the slightest idea when Copper Age started. Why? Because all the copper was later smelted into bronze. No, they didn't lose this valuable metal by the way, they cared about it, they transferred it to their children, they didn't just carelessly drop it in nature. The first valuables we find when the afterlife idea developed, when people were buried with their valuables, before that nobody was dropping their valuables by the way.
