Pterodactyls were suited well for flying. They had very light hollow bones and wide leathery wings. The body was long and very thin. Pterodactyls had good eyesight which was important for finding food.
They were carnivores and ate fish and other animals caught from the oceans. They may have been scavengers on land as well. Pterodactyls are actually not considered to be dinosaurs. They are classified as pterosaurs because they do not have an upright stance like dinosaurs. Pterodactyls are classified as reptiles and are very closely related to dinosaurs. They lived during the Cretaceous period about 144 to 65 million years ago. There are many different species of pterodactyls. One of the smallest Pterodactylus had a wing span of only about 20-30 inches. The largest pterodactyl found so far is Quetzalcoatlus, which could have a huge wingspan of over 40 ft. Pterodactyls lived in many parts of the world. They flourished for many millions of years before they became extinct at the end of the Cretaceous period about 65 millions years ago.
