I mean the group of ceratopsians and pachycephalosaurs. But yes, it's plausible, that every ornithischian had hairy filaments, since we know, that heterodontosaurs had those filaments.

Really nice! However Titanoceratops and Pentaceratops can not be synonyms, or better, if they are synonyms then also Utahceratops, Arrhinoceratops, Coahuilaceratops, Bravoceratops and Anchiceratops would be incorporated in this synonymy for a matter of phylogenetic logic.

The spines on the back look cool, they're almost like echidna spikesΒ
