Happy Dinosaur Week! Every episode this week explores the ancient marvels that walked the Earth millions of years ago. Fossilized bones and footprints help scientists figure out what these prehistoric creatures looked like – but how do we know what they sounded like? We asked paleontologist and science journalist Shaena Montanari to help us find the answer.

Got a question that makes you want to roar in frustration? Send it to us at BrainsOn.org/contact and we’ll find a dino-mite answer.
