Also,for sauropods and stegosaurs i mean quill like feathers

Ceratopsids are the only ones with any evidence of feathers so far.

I meant chasmosaurs and centrosaurs

Oh, so you mean Ceratopsidae?

Yeah

Quills is likely for centrosaurines and protoceratopids (there is proof for both), though chasmosaurines probably could have some too. Stegosaurs and sauropods are much less likely

Ceratopsians did have quills, at least some of them did. So at the very least the little ones would have some quills

What, which centrosaurine had quills?

^It appears I confused centrosaurines with chasmosaurines (I never remember what groups Trike and Pachyrhino belong to [or any ceratopsians for that matter]), my bad
