"SEM Studies of Fossil Flowers of the Southeastern United States".
Patrick S. Herendeen
Department of Geology
Field Museum of Natural History
Chicago, Illinois

Dr. Herendeen will discuss his research on the origin and diversification of flowering plants during the Cretaceous era which includes floral evolution and angiosperm wood anatomy. In his studies he uses fossil flowers, fruits, and seeds that have been preserved as charcoal or as mummified remains. Charcoalified material is particularly well suited for study of floral structure in fossil plants because the flowers are three-dimensionally and anatomically preserved. Since angiosperm systematics is largely based on floral structure, availability of three-dimensionally preserved flowers is critical to a aleobotanical investigation of floral evolution and diversification patterns in early angiosperms. In a slide/lecture presentation, Dr. Herendeen will emphasize his SEM work on the fossil flowers of the southeastern United States.
