Reconstructing a Jurassic soundscape

Reconstructing Jurassic insect sounds Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us. In this episode, Fernando Montealegre-Zapata and Daniel Robert reconstruct the sounds of Jurassic insects. In this episode, we cover: •[00:00] Introduction. •[00:55] Bioacoustician Fernando Montealegre-Zapata and sensory biologist Daniel Robert recount what was known before this study about the sounds produced by long-extinct animals. •[02:18] They tell us about the kinds of fossilized body parts they were able to study and how they produce sounds. •[03:45] Montealegre-Zapata and Robert talk about the tools they used to recreate the sounds these fossil animals produced. •[05:01] They describe pure tones, and why it's important to know that Jurassic insects produced them. •[06:22] Robert explains why it's important that some species could produce ultrasonic tones, and what that means for the evolution of later ultrasonic species like bats. •[07:13] Montealegre-Zapata and Robert recount other results about the diversity of sounds Jurassic insects produced. •[08:38] They list the caveats or limitations of the study. •[10:10] Conclusion.
