So, if not an extra-terrestrial impact, what caused the Permian extinction?  
Dan from "Roseanne" in "When Dinosaurs Roamed North America" assured us a comet 
broke up into five pieces and smushed us way back then.  

I trust Dan - he always seemed to know when the kids were going bad.   :-)

That and there seems to be very good evidence of super-craters for that time 
period.
