Pteranodon is one of the most famous Pterosaurs. This flying reptile lived on Earth in the Late Cretaceous 70 million years ago. With a wingspan of 23 to 30 feet, it moved by hovering over oceans to fish in the manner of our current pelicans. His jaw is devoid of teeth, which suggests that this very good fisherman swallowed the whole fish. The crest on his head counterbalanced with his elongated beak, and his skeleton was lightweight because of the hollow and thin bones of his wings.
