Pop-Culture vs. Science: Jurassic Park Sounds

What did dinosaurs sound like? How did extinct animals make and use sound? Like most behaviors, noises don’t fossilize, but there is some tantalizing evidence that paleontologists have pulled together about fossil bioacoustics. In this episode, we discuss how pop-culture may have misled us, and how scientists have gathered actual clues from living animals and the fossil record – and have even made scientifically-inspired ancient audios! – to reconstruct the sounds of the past.

In the news: hatchling insects, bird brains, old flowers, and dinosaur noses.
