That was one interpretation, and I'm not sure if it was ever even published. It was some sort of structure that was interpreted as "basis" for quills, the supposed quills themselves were not preserved. One paper this article cites about the specimen says "In all of these taxa (Psittacosaurus, Carnotaurus, Triceratops), it is unlikely that the feature scale bore a spine or a “bristle”-like structure—similar to those seen on the tail of Psittacosaurus—although bristle-like projections are present on some scales in the early-branching neornithischian Kulindadromeus48,49."[1] We should certainly go in more detail about this, though. I will add a photo of the skin impression. FunkMonk (talk) 06:00, 17 March 2024 (UTC)[reply]
