The inside says "Don't you feel better now?"

I do... Also, I really appreciate students who take the time to do things like buy their professors birthday cards. I've got some good ones here!

All those warm fuzzies aside, though, we should point out for the record:
Issue #1: The oldest cave paintings (in Europe) are ~32,000 years old, not "3.2 million."
Issue #2: That's a really old dinosaur. Most dinosaurs are much younger. It's been suggested the divergence from archosaurs occurred ~230 Ma, so this isn't the most representative age for a dino.
