Listen to a Jurassic forest

Scientists have reconstructed what a Jurassic forest might have sounded like 165 million years ago, and the one-minute audio is a really cool soundscape to imaginatively step into. They created it by analyzing and modeling the sound-producing structures preserved in 20 fossil insect wings from nine species that lived together in what is now Inner Mongolia. It’s a diverse chorus of low trills and high-pitched chirps, and I wish I could loop it all day as background noise. — CD
