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, Kay Behrensmeyer and Ben Kligman describe what a fossil bone bed in Arizona reveals about a 209-million-year-old pterosaur and its ecosystem. In this episode, we cover: \u2022[00:00] Introduction \u2022[01:01] Paleoecologist Kay Behrensmeyer and paleontologist Ben Kligman describe the discovery of this fossil bone bed. \u2022[03:10] Kligman and Behrensmeyer introduce a previously undescribed pterosaur. \u2022[05:00] They talk about what this specimen says about the ecology and evolution of pterosaurs. \u2022[06:15] Kligman and Behrensmeyer talk about the importance of studying this fossil community. \u2022[07:52] They explain how their methods can improve paleontology and discovery of small fossils. \u2022[09:08] Behrensmeyer and Kligman talk about the study\u2019s caveats and limitations. \u2022[10:10] Conclusion.
