Extinction bites ping.
Dinosaurs were British? Who knew?
Or, according to GodGunsGuts, life preservers.
;-)
What I would like to know is how many of our tax dollars went to research this stupid as hell project.

They say a related parasite infects birds, but birds aren’t going extinct from it. Dinosaurs were around for millions of years, then rather suddenly all went extinct, except for their descendants, the birds. What is the age range of the infected fossil bones? Was the parasite around for a long time before the dinosaurs died out? This argument doesn’t have teeth.
Being able to breathe underwater for the better part of a year 4,000 years ago could have helped too.
I don't blame them...after word got out that tyrannosaurs tended to eat dentists, no dentists wanted to operate on them. Usual story--a few bad apples spoil it for everyone else, even the gentle, well-behaved dinosaurs. If they'd all been like Barney, they'd still be around.

Tyrannosaurus Rex had a head four feet long
And that made it hard to buy a toupee.
His teeth were seven inches long
And he had teeny little arms
And that made it hard to brush everyday...
