Pachycephalosaurus expressing Fluorescent bones, much like those seen in Chameleons.
Since the skull of Pachycephalosaurus is very readable as âvery shrink wrappedâ with almost every scale visible on its surface, Iâd figure it to be the best dinosaur to play with this concept of bones fluorescing (Emitting visible light under a blacklight) since theyâd be easily visible on its face.
If anything itâs a very neat spec piece, Other good candidates for evolving this ability could be Ceratopsids, Stegosaurs, or Ankylosaurs. But thereâs no guarantee any of these clades expressed this trait at all, as itâs fairly rare in Tetrapods.
