Quaternary Paleobotany Laboratory
Our lab conducts paleoecological research through the study of plant remains (macrofossils, pollen, charcoal) preserved in the sediments of lacustrine, fluvial, and wetland environments. Cores extracted from these settings contain sediments deposited over thousands of years during the late Quaternary. Plant remains found within cores provide records of past vegetation and environmental change.
