Eocene-Oligocene Climatic and Biotic Evolution
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 f...
The Eocene-Oligocene Transition
After a decade of new findings and interpretation based on innovative techniques during the 1980s, archaeologists were pretty sure that 38 million years ago the earth still basked in a subtropical "greenhouse" that had lasted since the age of dinosaurs, but 5 million years later there were glaciers in the Antarctic, signalling the beginning of the "icehouse" state that we know now. Here is a summary of the present understanding of the climatic and biological changes, for nonspecialists who have some familiarity with the terms and concepts of archaeology.

Terminal Eocene Events
The papers in this volume provide an exhaustive inventory and description of the most complete sedimentary sequences across the Eocene-Oligocene Boundary (EOB) from all over the world, and present a synthesis of the biotic and chemico-physical events detected at the Eocene-Oligocene transition. The content of the book represents the results achieved by Project no. 174 on ``Geological Events at the Eocene-Oligocene boundary'' of the International Geological Correlation Program, sponsored by UNESCO. The project was carried out over a five year period and has provided a wealth of new and interesting information.
