"Last time it blew BIG it took out the dinosaurs (IIRC)"

I think you'll find that your time scale is off by about a thousand.

Yellowstone blew in the last hundred thousand years, while the dinosaurs quit romping around sixty-five million years ago, presumably (with good evidence), because of the chicxulub meteor.

I guess IDNRC.

I need to do a little research and get back to this.

Actually, I thought the Dinosaurs disappeared due to Rising Expectations.
