[meteorite-list] Extinctions

[E.P. Grondine]

Hi Paul - 

Denial is not simply a river in Egypt anymore.

I wonder if the new NASA data show the 3 extinctions between each of those 100 million year extcintions. Its funny how the press release data make no mention of them, but then there's nothing funny about the battle between Morrison and Muller and Clube and Napier, and asteroid versus comet impact. 

The lake cores will be re-examined, and we will see if the dates hold. I doubt if they will.
