Evelyn, I like Pterodactyls too, but they weren't dinosaurs. Dinos can't swim or fly so they are land animals. I hope that you will learn about the different types of Prehistoric creatures in my next adventure. Mosasaurs and Plesiosaurs ruled the sea while Dinosaurs ruled the land. See the changes from amphibians to reptiles-mammals, and birds.
Thanks and keep the questions and comments coming.
