Lucy Edwards

Lucy E Edwards focuses her research on the stratigraphy of the Atlantic and Gulf Coastal Plains. Her specialty is dinoflagellates (a type of algae), and she studies their fossil cysts for what they reveal about the time and environment of deposition and how they came to be preserved in the fossil record. She also specializes in stratigraphic nomenclature and methods of stratigraphic correlation.
