The sound of a Jurassic forest, recreated using fossils and AI

Sounds play such an important ecological role, but palaeontologists have always had to use their imagination when reconstructing the sound of extinct landscapes: Until now! For the first time a team of scientists have reconstructed the sound of a whole palaeo-community. Using fossil insect wings and some technological approaches to modern animals, the team were able to use physics and AI models to reconstruct the acoustic landscape of a Jurassic forest peppered with the calls of insects. Were the animals avoiding predators or just talking to each other? Listen in and find out. 

This week's paper is "Reconstruction of an extinct soundscape reveals ultrasonic communication in the Jurassic" by Jun-Jie Gu, Fernando Montealegre-Zapata and colleagues published in Proceedings of the National Academy of Sciences in August 2026 https://doi.org/10.1073/pnas.2615107123
