Fossils might give a good image of what dinosaurs looked like, but they can also teach scientists what they sounded like. The Parasaurolophus is a duck-billed dinosaur with a unique crest that lived 70 million to 80 million years ago.

Hongjun Lin from New York University will present results on the acoustic characteristics of a physical model of the Parasaurolophus’ crest as part of the virtual 187th ASA Meeting. Lin created a physical setup made of tubes to represent a mathematical model that will allow researchers to discover what was happening acoustically inside the crest.
