The Polly Lab

We study vertebrate paleontology with a focus on how earth history, especially changing climates and geographies, has affected vertebrate evolution and community composition. Our work includes trait-based studies of community responses to environmental change, geometric morphometric analysis of evolution and morphology, phylogenetics, biogeography, and speciation. Our studies synthesize data from regional and continental geographic scales and across historical, Quaternary, and Cenozoic time scales. We are part of the Geobiology Group of the Department of Earth and Atmospheric Sciences, Indiana Univesrity.
