So you are not referring to the 50 k Barringer Meteor Crater. Where is the one that is 5 to 13 k? Does it have a name?

See my #56 this thread.

Here's a link to some info on this new theory.

You will see a reference to 34,000 years ago at the beginning of the article.
Ignore that date, as the 13,000 year references are made farther down.

Somewhere I have a chart of meteor sizes and impact effects. I will try to find it and send out to you all.

Of course, air bursts are a separate category, also potentially very lethal.

I saw this on National Geographic. The diamonds are inside tiny, carbon balls (I forget their names). It was truly fascinating.

seriously disrupted the development of the early human civilisations that were emerging in Europe and Asia......

Maybe. Maybe it destroyed the substantial existing civilization and it took 2000 years to get back to some kind of functional civilization with trade, etc.

Now I remember. The carbon spheres are call Buckyballs. They look like soccer balls.

I wonder if events like that explain why the oxygen content in the atmosphere has gone from low 30’s to around 22% over the eons.

Perhaps it was burned off in the fires.

The buckyballs also contain He3, that miraculous nuclear fuel they want to mine from the moon.
