Now that, my friend, is a beautiful dinosaur. Almost like a musical instrument, Parasaurolophus used their crest for long distance communication.

There’ve been simulations in the past that tried to reconstruct how they could have sounded, but nothing quite compares to the real thing.

They didn't use their tube-shaped crest as a snorkel, contrary to previous hypotheses. Nevertheless, I quite like the mental image of a Parasaurolophus going snorkeling.

The crests are made out of bone riddled with hollow tubes, which help amplify that beautiful singing voice of theirs. You're listening to the first orchestra on Earth.
