The End of the World!

[Raistlin]

Error! Closer to about 6000 years so far. Dinosaurs died out during Noah's flood. They didn't live millions of years. But the day will arrive when billion-year life is possible.

I don't know you well enough to tell if you're joking. Please tell me you are.

Anyway, regarding the current discussion, saying "dinosaurs lived for hundreds of millions of years" is a bit of a misnomer. Sure, the "dinosaur period" was something like 200 million years, but thousands of species dinosaurs evolved and became extinct during that period, well before the 65-million-year extinction. There is no "dinosaur" species, but a collection of countless thousands of species, none of which themselves lasted hundreds of millions of years.
