If I understand the term correctly, all dinosaurs had *some* sort of 
integument, the integument being the skin and any appendages thereupon.

If you draw a dinosaur with naked skin, I would say you are putting forth the 
hypothesis that the animal had naked skin, which, for the taxa under 
discussion, is less parsimonious than the hypothesis that they had fuzzy or 
feathery skin.
