Eocene-Oligocene Climatic and Biotic Evolution

by Donald R. Prothero (Editor), William A. Berggren (Editor)

The transition from the Eocene to the Oligocene epochs was the most significant event in earth history since the extinction of dinosaurs. As the first Antarctic ice sheets appeared, major extinctions and faunal turnovers took place on the land and in the sea, eliminating forms adapted to a tropical world and replacing them with the ancestors of most of our modern animal and plant life. Through a detailed study of climatic conditions and of organisms buried in Eocene-Oligocene sediments, this volume shows that the separation of Antarctica from Australia was a critical factor in changing oceanic circulation and ultimately world climate. In this book forty-eight leading scientists examine the full range of Eocene and Oligocene phenomena. Their articles cover nearly every major group of organisms in the ocean and on land and include evidence from paleontology, stable isotopes, sedimentology, seismology, and computer climatic modeling. The volume concludes with an update of the geochronologic framework of the late Paleogene.

About the author

Donald R. Prothero is a Professor of Geology at Occidental College and Lecturer in Geobiology at the California Institute of Technology. He teaches Physical and Historical Geology, Sedimentary Geology, and Paleontology. His specialties are mammalian paleontology and magnetic stratigraphy of the Cenozoic. His current research focuses on the dating of the climatic changes that occurred between 30 and 40 million years ago, using the technique of magnetic stratigraphy. Dr. Prothero has been a Guggenheim and NSF Fellow, a Fellow of the Linnean Society, and in 1991 received the Schuchert Award of the Paleontological Society for outstanding paleontologist under the age of 40, the same award won by the renowned paleontologist Stephen Jay Gould. He has authored or co-edited numerous books, including Horns, Tusks, Hooves and Flippers: The Evolution of Hoofed Mammals, the best-selling textbook from McGraw-Hill, Evolution of the Earth, Evolution: What the Fossils Say & Why it Matters, Bringing Fossils to Life, After the Dinosaurs, and the textbook Sedimentary Geology. He is also a Technical Editor of the Journal of Paleontology.
