Parasaurolophus walkeri | What did Parasaurolophus SOUND like?

Parasaurolophus -- "Near Crested Lizard" Parasaurolophus was a duck-billed dinosaur with an extremely long, backward-sloping, bony crest. This was hollow and as large as the rest of its skull. Researchers believe that this served to produce a foghorn-like sound at low frequencies. Parasaurolophus was a herbivore that ate pine needles, leaves, and twigs. Fossilized stomach contents have been found, consisting mainly of terrestrial plants. Parasaurolophus probably migrated in herds like other duck-billed dinosaurs.
