Strange and wonderful creatures shared the earth with the dinosaurs. Kronosaurus ruled the seas with teeth as big as bananas and jaws more powerful than a Tyrannosaurus rex's. Flying Pterodaustro spit water through hundreds of long, thin teeth. Deinosuchus, the giant crocodile, preyed on unlucky dinosaurs. These and other amazing animals are introduced to young readers in easy-to-read text and dynamic illustrations.
