Re:Oh, so this theory is back... (Score 2, Informative)

I posted earlier that I had heard this on NPR, when they were discussing it they didn't say that the meteor was the whole cause of the die off, they believe that when the meteor impacted (in the ocean incidentally which may explain the lack of ejecta you speak of, though it seems unlikely) that the impact sent a shockwave in the core, causing siesmic and volcanic activity on the other side, which would be the main cause of the die off. Now I don't claim to know everything, I'm just quoting what I can remember, so if you can tell me a little more about why that would not be possible then I would be more inclined to believe that it was only volcanic activity. But the theory and it is just that, as all things speaking of events 250mm years ago, seems reasonable enough to me. Cause and effect my good man.
