When did mammoth die?

You can't get a good DNA stratigraphy from the banks of a river that floods:

But in broad terms I have no problem with mammoth being hunted after 45,000 BCE, and the hunting efficiency much improving with the adoption of Clovis.
That still does not explain the abrupt abandonment of quarries around 10,900 BCE.

There is an account by an early exploring party somewhere in the Illinois (?) area being invited by the locals (since everything seemed interesting to them) to make a one or two-day side trip to see mammoths. But they decided it wasn't important enough to deviate from their schedule. Wish I'd taken notes now.

Hi uniface -
Perhaps you'll enjoy this story as well:

(found during a search for AGU YD coverage)
It's too bad Thomas Jefferson's papers on the First Peoples were lost during his move from Washington back to Monticello. You might want to check his Notes on the State of Virginia, he was hoping and thinking that mammoth had survived.
Or for the real story go here (more accounts than in my book):

The First Peoples in the south remembered cometary impact. But as Jefferson put it referring to meteorites: "I would prefer to think that two Yankee professors lied rather than that stones fell from the sky."

I see paleo-anthropology is undergoing re-organization. Here you go:

A re-organization that's already taken 3 full weeks. An awful long time...
Makes me wonder if we'll ever going to see it back up.
I'm not holding my breath.

Hi uniface -
They found those as well, but they are NOT related to the YD impacts. The search is on for the craters from two far earlier large iron impacts, one in Alaska, one in Siberia. My guess is that the Alaskan one probably marks the end of Cmt DNA migration, with A mt DNA following, but we'll see.

No mention of space particals here,
but has anybody looked?

It said (if an aging memory serves) they were from an impact older than the Topping-Firestone Big Bang over Michigan (or thereabouts) that whacked the Clovis folks.
It would be helpful to have a timeline chart of them. (When/where/what result) (?)

Well, at least it's fashionable...
And of course much more theatrically dramatic than a flu epidemic! Or a plethora of other also 'mundane' causes of (mass) death. No less lethal or effective, though.
Until this solar flare novelty wears off too, of course, because that's inherent to novelties, and the next mass extinction theory becomes en vogue.
We need to get to grips with the fact that extinction is the norm, in nature. While succesful evolution is the exception! Not the other way around.
A thousand times more species have gone extinct, over the aeons, than are alive today.

"Solar flare" does not explain the nanodiamonds found.

I am not on my home machine, but seem to remember dates for Siberia around 25,000 BCE and 34,000 BCE for Alaska from Firestone's poster on the tusks. The search is on for the craters in the regions, but can't be narrowed down any more in the "where" than that yet; I will correct these dates when I get to my computer.
The exact role of impacts in mt DNA haplogroup division is still unclear.

Good point.
