Overview

The transition from the Eocene to the Oligocene epochs, from approximately 47 to 30 million years ago, was the most dramatic episode of climatic and biotic change since the demise of the dinosaurs. The first part of the book summarizes the latest information in dating and correlation of the strata of late middle Eocene through early Oligocene age in North America. The second part reviews almost all the important terrestrial reptiles and mammals found near the Eocene-Oligocene boundary. This is the first comprehensive treatment of these rocks and fossils in over sixty years.
