FLYING REPTILES ALSO KNOWN AS PTEROSAURS ARE AN EXTINCT CLASS OF REPTILES THAT UNDERWENT A UNIQUE EVOLUTIONARY ADAPTATION IN THE HAND WHERE ONE FINGER BECAME EXTREMELY LONG AND SUPPORTED A MEMBRANE WHICH WAS USED TO CREATE LIFT GIVING THE REPTILE THE ABILITY TO FLY.

 

THESE REPTILES WERE WELL KNOWN FOR HAVING VERY SMALL BODIES FOR THEIR OVERALL SIZE AND HOLLOW BONES MAKING THEM EXTREMELY LIGHTWEIGHT.
