Hair and feathers are preserved in fossils. That’s how we know dinosaurs have feathers.
But how about fat? Could they have been chunky like penguins?
This is actually a problem https://www.buzzfeednews.com/article/natashaumer/dinosaur-animals
those artists tend to base their drawings on the fossils alone, while ignoring what the animal might have looked like with layers of fat and other things.
That’s not true. They are modeled that way since they are reptiles and that’s the fat proportion of reptiles.
But than again they are related to birds so we don’t know
Pterosaurs also independently from mammals evolved a form of hair.

Looks more like George, the resident homeless wino. Support your local George!

Like Joey Ramone?
We know that they have feathers, you should ask question how, if they are not preserved…
We know they have fathers thanks to fossilized pages of early Bird Law text books from about 68,083,000 BC
