Scientists recreate sounds of Jurassic katydid relatives from fossil wings

Researchers analyzed fossilized wings from nine species of Jurassic katydid relatives found in Inner Mongolia, dating back 165 million years. By measuring the microscopic ridges that produce sound and using computer models, they reconstructed the likely calls of these ancient insects. The study, published in PNAS, offers a glimpse into the acoustic environment of a Middle Jurassic forest.
