I think the article just has a poorly selected title. The real interesting new research it's presenting has nothing to do with how dinosaurs looked. It's really about a possible discovery in dinosaur physiology: that they produced melanin in more than just their skin, which implies that animals might have uses for it beyond just pigmentation.

Yes, exactly. It's really not even limited to dinosaurs.

Nor any descriptive text except for saying that some dinosaurs had feathers, which most people already knew.
