Was Dino extinction an inside job?

Researchers are now claiming that massive number of dinosaur deaths might be due to a volcanic explosion. Note that previously 'an asteroid killed them' was the popular theory amongst most scientists.

Keller and others now say more about the life-extinguishing work of a massive series of sulfur dioxide-spewing volcanic eruptions that occurred in what is now India at the time of the dinosaur-destroying K-T mass extinction (the shorthand given to the Cretaceous-Tertiary extinction).

From what I read here, neither theory is either booted out or hailed as the sole culprit. The consensus seems to be a joint effort, if you can call it that.

And some naysayers say that humans have discovered all there is to be er, discovered. Pish posh.
