     Note: The wings were formed, like those of bats, by a
           leathery expansion of the skin, principally supported
           by the greatly enlarged outer or " little" fingers of
           the hands. The American Cretaceous pterodactyls had no
           teeth. See {Pteranodontia}, and {Pterodactyl}.
