The Stegosaurus.

Parasaurolophus. I think they're cool-looking.

Golly! Do I really have to choose?? Well, if I gotta, at the moment it's the Armored Tank varieties. They were the winners of the arms race. Most predators were leaving them alone. Sharp spikes, heavy, strong and lethal tails...yeah it was good to be a ankylosaur and their relatives.

The brontosaurus. I think they are beautiful creatures. Strong and powerful, but they wouldn't hurt a fly.

The brontosaurus' are one of the reasons why I think it's a pity that dinosaurs are extinct. I'd love to see a bronto migration.
