Re: Hydrogen fusion killed the dinosaurs?

"I have found no dinosaur expert who thinks much of this idea, or who
believes any of the dinosaurs were mammals."
There isn't quite as many as one mammal expert who believes this either, as
far as I'm aware. This 'theory' has about as much supporting evidence as
extinction by alien big game hunters. Mammals are synapsids, and synapsids
as a distinct line of amniote vertebrates have a history going back into the
Upper Carboniferous. If Morganucodon is allowed as a mammal, then mammals
are known from the Upper Triassic; a slight 150 million years prior to the
K-T die-in. Extinction by alien big game hunters, on the other hand, is
harder to rule out.
The Mesozoic - more than just the dinosaur
