Molly E. Karnes studies how chemical signatures, especially isotopes of elements like zinc, carbon, copper, and thallium, can be read from fossils, minerals, and living organisms to reconstruct past environments and diets. A major thread of the work uses shark teeth to figure out where sharks (including the extinct giant Megalodon) sat in the food chain and how their feeding varied over time. Other projects apply similar isotope tools to volcanic rocks and metal ore deposits.
