Final answer:
A winged reptile with a thin, bony crest on top of its head used for balance during flight is likely a Pteranodon, a prehistoric flying reptile distinct from dinosaurs.
Step-by-step explanation:
If you were a winged reptile with a thin, bony crest on top of your head, which may have helped you to keep your balance while flying, then you are likely to be a Pteranodon. The Pteranodon is known for its distinctive head crest, which varied in size and shape among individuals. These prehistoric creatures were not actually dinosaurs but were part of a group of flying reptiles known as pterosaurs. Pteranodons lived during the late Cretaceous period and could have wingspans up to 7 meters (23 feet). Their hollow bones and elongated fourth finger that supported the wing membrane allowed these magnificent creatures to soar in the skies of ancient earth.
