Quoting K and T Dykes <ktdykes@arcor.de>:


<<It does look like two events caused the end-Cretaceous extinction.>>

Does it?

I'd wager that it takes more than just a single event (probably even more than two coincidental events) to cause a mass extinction. No doubt a whole lot of bad luck just happens to coincide (impact/s, volcanism, climate change, methane belches, etc).
