Pterodactyls (or pterosaurs) lived between 150 million and 70 million years ago. These extraordinary reptiles were able to fly. Some had a wing-span of over 25 feet, making them by far the largest flying animals known to man. Their skulls were often longer than four feet.
Unlike the birds, their descendants, pterodactyls must have been unable to perch upright. They probably hung upside down like bats when sleeping or at rest.
Since most remains of pterodactyls have been discovered among marine sediments, it seems likely that these flying dinosaurs found their food in the sea, like seagulls, by diving for fish.
