So this mastodon bone find was around 2017, but the lady I spoke to was 30 years ago or more, so there is probably other information about such disputed finds out there. At any rate the date given was also given almost another 10,000 years earlier or later, so 120,000 to 140,000 years ago. Perhaps a find from closer to the earlier date as less melting of vast ice sheets would have occurred, and a wide Bering Strait land bridge would still have been available for a time.
Several other thoughts. Could similar ancient genetic traces be found in north Asian peoples and some of the older, more primative western North American peoples. It is believed our recognized early Americans followed the mammoth herds over the Bering landbridge from Asia into North America. Not unreasonable that earlier Mastodon herds might have been followed. In this case a young one, easier to kill. Also, there is the still unsatisfied question of possible Sasquatch(sp?) hominids in our northwest regions. Could they be a somewhat primativized remnant of a more developed group of people who barely survived the trip(s) and regressed to a less cultured remnant.
I’ve been sitting on another possible post about how older tribes followed the mammoth herds.

The 130K old Calico site is probably the one you’re thinking of.

DNA wise, anecdotally, I have a trace of Precolumbian DNA, but it comes from the other direction, i.e., from Siberia into Europe. It just happened to drop through to me. :^)
The Clovis-first-and-only is a ridiculous construct. It’s obvious that there have been multiple movements into the Americas (and maybe out as well), and within the Americas, just as there have been everywhere else in the world.
