Episode 274 | GSA 2017, Part 2
00:00:00 - Now for part 2 of our coverage of GSA's annual meeting in Seattle, WA. First up, Ryan's conversation with Robin Trayler, who does stable isotope work on South American mammals (but not sloths, they're spoken for, thank you very much). He explains how stable isotopes from animals can teach us about past climate. You can read his abstract here: Ecology and Climate of the Early Miocene Santa Cruz Formation, Argentina
00:20:16 - Next up is the delightful Dr. Lindsey Yann, who is also working on stable isotopes in mammals, but she's looking at white-tailed deer from an archaeological site in Tennessee, so similar tools to answer different questions. Neat! Her abstract: Deer as Potential Climatic Recorders Through Time
00:39:11 - In the spirit of Thanksgiving, Ryan brought Patrick a beer, in this case, a pretty big one, the Megalodom from Ninkasi Brewing Company, named for a pretty epic (but definitely extinct) shark. A brief discussion of Ryan and Patrick's issues with taxonomy ensues.
00:52:38 - Finally, Ryan's field partner from undergrad, Harrison Gray, who is finishing up his doctorate in Geomorphology and does a great job of breaking down the methods he's developed for understanding the history of a rock and its role in the landscape. He also works for the USGS, though not for much longer, so we do speak a little about the politics of making it harder for government agencies to hire young scientists to serve the nation's interests. Strap in. His abstract: Testing Age Predictions Made with Portable OSL Measurements in Southern Nevada
01:13:32 - PaleoPOWs are a lot like spending time at a conference, you could bump into anyone! First up, we thank Ryan's parents, Bruce and Susan, for their support on Patreon. As part of the reward for their generosity, they get a thesis title: A quilted layering for Chondrichthyan cartilaginous insertion of the patellar joint, a test case performed in New Mexico, USA. It may be nonsense, but it's yours with our sincerest thanks. Next up, a fossiliferous update from Emma G. about the discovery of two fighting fossils Ryan mentioned in a previous episode. Last up, Kirstin M. asks why we stopped doing Trailer Trash Talk, her favorite segment, so we explain why while also sneaking in a quick peek at the teaser for Smallfoot, to really hammer the point home.
Cool rewards await you if you decide to support us on Patreon!
