Interesting tie-in (I swear I didn't know about this in advance): the meteor dun it.
When the Deccan Traps were mooted, their problem wasn't that volcanoes are a killer. Far be it from this blog. It wasn't even that volcanoes can wipe out life on a whole continent. I've always suspected they can; and that Yellowstone may well have held back the development of mammalian life on this here land Parias.
But the dinos weren't stuck on one single continent. They were on MANY continents. Cretaceous Earth was the exact opposite of Pangaea. Why wasn't there a continent of dinos like, as of 10 mya, there existed a marsupial continent (Australia) and an armadillo continent (America)?
This new study solves that. Maybe the Traps did for Decca, floating by itself in the middle of the Indian Ocean. But only Chicxulub, striking at the angle it struck, an alien from another world, had the power to do for us all.
