Oh... uh. Lemme think. Aerodactyl, Cranidos, Shieldon, Tyrunt, and Amaura are all dinosaurs or... well I guess technically Aerodactyl might not count but pterodactyls are close enough. Archen's also a sort of ancient bird thing. Omanyte, Kabuto, Lileep, Anorith, and Tirtouga are also more... ancient-ish Pokemon that look like they're based on some stuff from our world, and Relicanth is considered a 'living fossil' I think. Then there's all the Pokemon that could be either dinosaurs or dragons, depending on how you look at them.

I've got a Tyrantrum and an Aurorus - the evolved forms of Tyrunt and Amaura. They're named Wrecks and Amy. Wrecks... uh. Lives up to his name.
