She is particularly interested in what coprolites (fossil feces) can tell us about the paleobiology of dinosaurs and other vertebrates, and about trophic interactions in ancient ecosystems. Karen has an active field program in the Rocky Mountain region.

Her research focuses on mammalian evolution across the Cretaceous-Tertiary boundary (that infamous boundary when dinosaurs went extinct); and High Arctic vertebrate evolution, paleoclimate, and paleogeography during the Eocene (some 50-55 million years ago). Jaelyn has active field programs in the Rocky Mountain region and the Canadian High Arctic.
