Welcome to the website of Sarah Z. Gibson

I am Professor of Geology and director of the Earth Science Program in the Department of Atmospheric, Earth, and Geospatial Sciences at St. Cloud State University in Minnesota. My research focuses on the evolutionary relationships and major changes occurring in stem actinopterygian fishes in the Early Mesozoic, an exciting time in the history of the Earth. My work incorporates anatomy and morphology, within a phylogenetic context, to address questions related to how these fishes adapted and evolved to exploit new ecological opportunities following the end-Permian extinction event.
