![]() The creature's discovery has astounded scientists because their age puts them within two recognized groups of pterodactyls -- primitive long-tailed forms and advanced short-tail forms -- and they display characteristics of both. The combination of features indicates that the primitive pterodactyls evolved relatively quickly, and that certain groups of features changed at the same time. Traditional evolutionary theory suggests that one feature -- a tail for instance -- would slowly evolve over time. Not necessarily revolutionary, but a little helpful for scientists to pin-point the evolutionary track of the pterodactyl. Leave Comment:
