If this is true, what is the source of the material at the geologic K-T barrier?

That was my thought also, Sechs, until I read it a little more carefully and realised that they are talking about the Permian-Triassic mass extinction, not the K-T (Cretacious - Tertiary, i.e., the famous "dinasoaur killer" event.
This story is about the event 250 million years ago, not the more famous but somewhat less destrucive one 65 million years ago.

Ah. I'd never seen the P-T event referred to as the "Great Dying."
I was under the impression that vulcanism/plate tectonics was the generally accepted theory on this event - not an asteroid strike, as the story says.
