Scientists used fossil wings, lasers and AI to recreate the calls of insects from 165 million years ago; some Jurassic species were already communicating above human hearing

Scientists have recreated the calls of nine Jurassic insect species that lived 165 million years ago. Using fossilised wings, laser measurements, computer modelling and AI, researchers found that some insects made clear chirping sounds, while one species may have produced ultrasonic calls above the human hearing range.
