Pteranodon

Pteranodon was a large pterosaur that lived in Cretaceous North America. It was the size of a small airplane and was a contemptory of Tyrannosaurus

Diet
Pteranodon seems to have been a fish-eater, as its beak was very similar to the beaks of modern birds known to have a diet of mainly fish.

"Protofuzz"
Many pterosaurs have been discovered with a form of fur over their bodies. It is likely that Pteranodon had similar "protofuzz".

Headcrest
Pteranodon had a distinctive headcrest. Some specimens of the same age have crests of different sizes, suggesting sexual dimorphism. Alternately, it could have been used for steering itself in flight, or for some purpose unknown to us today.
