Little-known fact: Some dinosaurs wore hats.* And one group of duck-billed dinosaur had the best hats of all.
This hat (henceforth, we’ll call it a crest, for scientific accuracy) was not just any fancy accoutrement. Not at all. This crest contained the dinosaur’s nasal passages. That’s right; the dinosaurs breathed through a hollow crest on their head.
