pterodactyl

pterodactyl Any of several species of small pterosaur. Now extinct, pterosaurs were flying reptiles distributed worldwide in Jurassic and Cretaceous times. Pterodactyls were almost tail-less, with large toothed beaks and flimsy membranous wings. Fossil remains show a lack of muscular development and the absence of a breast keel. It is therefore believed that pterodactyls were gliders, incapable of sustained flapping flight.
