Bryn Mawr Research Associate Katherine Marenco conducted field work in western Utah this summer, for an ongoing project exploring the relationship between seafloor conditions and the evolution of marine communities during the Ordovician radiation. Also participating in the Utah expedition were Assistant Professor Pedro Marenco and Geology majors Alliya Akhtar and Danyelle Phillips, who focused their efforts on measuring and sampling Ordovician and Triassic stratigraphic sections for geochemical analysis. The group encountered plenty of wildlife – including four rattlesnakes – but came away unscathed.
