S. David Webb Title:  THE LAST BIG GAME IN THE SOUTHEAST Abstract: The megafauna in the southeast shared many continent-wide species, notably Mammuthus columbi, Mammut americanum, Equus species, Bison antiquus, Platygonus compressus, Megalonyx jeffersoni, and Paramylodon harlani. This region also supported its own distinctive fauna including Hesperotestudo crassiscutata, Cuvieronius species, Tapirus veroensis, Palaeolama mirifica, Eremotherium mirabile and Holmesina septentrionalis. Many of these species ranged around the Gulf of Mexico and into the American tropics where they still survive. Paleoindians impacted many of the species in both groups. Increasing evidence features Mammut americanum as a keystone prey in eastern North America. The classic Clovis/Mammuthus columbi association in the southwest was secondary to some other human/proboscidean association. If North America was peopled from Asia, they previously had hunted M. primigenius; if from South America, they began with Cuvieronius; and for transatlantic arrivals the proboscidean prey of choice was Mammut americanum. S. David Webb S. David Webb is Distinguished Research Professor emeritus of Zoology and Geology at the University of Florida and Curator of Fossil Vertebrates at the Florida Museum of Natural History in Gainesville. He received his B.S. degree in Zoology from Cornell University in 1958 and his Ph.D. in Paleontology at the University of California at Berkeley in 1964. He taught at Yale University Department of Geology and Geochemistry in 1976. His research interests include biogeography and evolution of fossil mammals during the past 20 million years. He has focussed on developing Florida's fossil record, but has also worked widely in North, Central and South America. He has published over 150 scientific papers, and six books, including editing "First Floridians and Last Mastodons: the Page-Ladson Site in the Aucilla River" (in press at Springer Verlag). Dr Webb founded the Florida Paleontological Society in 1974, served as president of the Society of Vertebrate Paleontology during the early '80's, was a Guggenheim Fellow in western Europe during 1974, and led the U.S. delegation to the International Quaternary Congress in Beijing in 1991.
