Marine Ecosystems in Deep Time

The Paleo-FISHES Lab explores marine ecological and evolutionary dynamics across environmental change throughout earth's history, using the past as a key to understanding the present and future. Our primary toolkit includes microfossil fish teeth and shark scales (ichthyoliths), which we use alongside paleoceanographic, paleoclimate, and paleontological records to reconstruct marine ecosystem dynamics and vertebrate evolutionary processes in deep time and across major environmental change events in Earth's history.
