![enter image description here][1] In early 2016, Dr. David Flannery traveled to Seymour Island off the Antarctic Peninsula as part of a Caltech-sponsored research expedition. Among the samples he collected were 45 from a stratigraphic interval that spans the mass extinction event at the Cretaceous/Paleogene (K/Pg) boundary. The Zinsmeister section (named for a geologist who had previously studied the site) consists of grey siltstones that are poorly consolidated as well as concretions that often contain fish and other vertebrate fossils. Flannery collected samples at 30cm intervals by digging beneath the weathered surface. The extreme cold made collecting hand samples challenging. **Contents** **The Samples** **Analyses** [1]: https://guardian.jpl.nasa.gov/images/tribandLogo.svg
