While there are a lot of dinosaur fossils, and a lot of plant fossils, the precise connection between the two has been something of a mystery. Now, <a href="https://www.sciencefriday.com/segments/dinosaur-stomach-bird-prairie-dogs/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">researchers report</a> that they’ve found what’s called a cololite, fossilized gut contents, in the remains of a sauropod—a massive, long-necked plant-eater. The dino’s last meal dates back 95 to 100 million years. Paleontologist Stephen Poropat joins Host Flora Lichtman to dig into the mysteries of a dinosaur’s tummy.And, for prairie dogs, communication is key. The rodents’ yips and barks can warn when danger is near—and not just to other prairie dogs. A <a href="https://www.sciencefriday.com/segments/dinosaur-stomach-bird-prairie-dogs/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">new study</a> suggests that birds called long-billed curlews are eavesdropping on this chatter to learn when a predator is lurking nearby. Using speakers and a taxidermied badger on wheels, ornithologists are untangling the social dynamics of black-tailed prairie dogs. Host Flora Lichtman talks with study author Andrew Dreelin about this eavesdropping behavior and what it means for conservation.Guests:Dr. Stephen Poropat is a paleontologist and deputy director of the Western Australian Organic and Isotope Geochemistry Centre at Curtin University in Perth, Australia.Andrew Dreelin is a research fellow with the Smithsonian Conservation Biology Institute and a PhD candidate at Northern Illinois University.Transcripts for each episode are available within 1-3 days at <a href="https://www.sciencefriday.com/segments/dinosaur-stomach-bird-prairie-dogs/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">sciencefriday.com.</a>
