General / Off-Topic Pterosaurs Were Possibly Feathered

Interesting, it does look more like fur though.
I think it's easy - soon as you hear the word feather - to imagine a highly evolved 'quill', a modern feather.

But I think probably two reasons why a pterosaur's feathers probably would resemble fur.

Firstly pterosaurs doesn't use feathers for flight. A membrane of skin, like a bat, rather than flight feathers obviously, pterosaur feathers don't need to be structurally strong.

Secondly protofeathers I think do look like fur, like example II.

If the animal doesn't use them for flight, then it probably does find them good for insulation. So even if a protofeather covered wing is less efficient in the air than plain skin would be, the advantages of surviving colder climates might make it a worthwhile trade off anyway, if it opens up a niche polar food source or breeding ground say.
