Give a talk to children and tell them dinosaurs didn't drag their tails, and you get arguments.

Children have a great urge to learn about dinosaurs.

Most people looking for dinosaurs are looking for beautiful skeletons.

Dinosaurs replace their teeth throughout their life. And T. rex replaced all of their teeth every year.

Dinosaurs are built just like birds - they can squat down, they can get up. Mammals, when we lay down, we throw our legs out to the sides - birds cannot do that. Dinosaurs could not do that either.

Keratin can be very colorful, as we see in birds. We'd expect dinosaurs to be very colorful because they basically invented the characteristics we see in birds.
