Wikipedia definition
1. PterodactyloideaPterodactyloidea (derived from the Greek words πτερόν "wing", and δάκτυλος "finger" meaning "winged finger", "wing-finger" or "finger-wing") forms one of the two suborders of pterosaurs ("wing lizards"), and contains the most derived members of this group of flying reptiles. They appeared during the middle Jurassic Period, and differ from the basal rhamphorhynchoidea by their short tails and long wing metacarpals (hand bones). The most advanced forms also lack teeth.
