Note the date of 35,00 years before present. Also in the article there was something about 20,000 year earlier.
It is entirely possible there was more than one of these events. Remember the Tungusku (sp?) air burst over Siberia in 1908. There was also a significant air burst over the Amazon mid last century. Also I think more attention needs to be paid to major vulcanism. There have been recent posts about the Toba supervolcano (diameter 18 by 65 miles about 74 thousand years ago) which may have decimated the human population. The modern Japanese volcano Sakara-jima is on the edge of a 15 mile diameter which has been dated as around 22,000 years old. Just look at the mess Pinatubo with a 3 mile diameter crater made. I think the last suspected Neanderthal remains were from around that time. Does anyone have dates and sizes of other major volcanos since Toba?
No. But, I like the way you think and my heart would sing if you were to follow up with that data.
