No. But, I like the way you think and my heart would sing if you were to follow up with that data.
Other big volcanoes?
I think there were several really big explosions of Vesuvius, including one around 25,000 ya. I did not see a crater diameter for them. The age on Barrington Meteor Crater is about 50,000 years, although it is not nearly as big as the 2 mile diameter crater they seem to have discovered in the Iraq Marshes (thanks, Blam). Still, I wonder what affect it might have had.
You may recall that I told a couple of you that I was accumulating data for writing something on catastrophes throught the ages and their influence on the development of life on earth. Because of the many new pieces of information I have received from you all in the past year, I may start out by focusing on the past 100,000 years and the development of modern man, and aiming it toward younger (teen) readers. I think there is enough for two books.
