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
Christos (given name) gave other anthropological examples of the need felt to distinguish between the "sacred" and the "profane", and university professor Giorgos Veloudis added το Cavafy's examples the distinction between the "profane" word Σταύρος (the name "Stavros") and the "sacred" word σταυρός ("cross").
