They appeared during the middle Jurassic Period, and differ from the basal (though paraphyletic) rhamphorhynchoids by their short tails and long wing metacarpals (hand bones). The most advanced forms also lack teeth, and by the late Cretaceous, all known pterodactyloids were toothless. Many species had well developed crests on the skull, a form of
Greek rock lizard within the range . It is typically found near streams and pools, in light woodland, at the edge of fields bordering woodland and in shady areas of rock or scree.
