First Floridians And Last Mastodons: The Page-ladson Site In The Aucilla River (topics In Geobiology)

This book presents the multidisciplinary results of an extensive underwater excavation in north Florida which yields the most complete results of interactions between early Paleoindians and late Pleistocene megafauna, especially Mammut americanum (American Mastodon), in a rich environmental context in eastern North America. It provides fundamental insights into two urgent issues: "The Peopling of the Americas"; and "The Extinction of the Megafauna."

The authors describe and illustrate their unique methods of precise underwater excavations. They show how these techniques allowed them to collect a diversity of zoological, botanical and cultural material with outstanding organic preservation.

This wealth of prehistoric evidence was recovered during twenty years of delving into an ancient sinkhole in the bottom of the Aucilla River. The nearly continuous sequence of fine-grained sediments, with an abundance of carbon dates, place the climatic and environmental history of this area in a global context of late glacial climatic cycles. The deepest strata produce clear evidence that the first Floridians lived and hunted here some 14,000 years ago, indicating that this southeastern culture preceded classic Clovis culture in western North America.

Clever studies of stable isotopes tell that the Mastodons migrated north out of Florida into glacial terrain during the winter and spring and their digesta, which also contain steroids and epithelial cells, display a rich summer diet.

The last section of the book provides a wealth of new evidence from the early Holocene about the flora and climate and how early Archaic people subsisted after the megafauna became extinct.
