Book Description
Here twenty-one leading paleontologists use important refinements in fossil diversity data to provide critical evaluations of older hypotheses of diversification and extinction processes and to propose fresh interpretations. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.

"This detailed study of silicified Ostracoda from part of the Esbataottine Formation provides a basis for correlation of circum-cratonal early Middle Ordovician rocks of North America and consideration of their conditions of deposition." --

Book Description
Two measured sections of the upper Rabbitkettle Formation in the western District of Mackenzie are separated by a thrust fault. These sections provide a record of silicified tribobite faunas across the Cambrian-Ordovician boundary in open marine carbonate rocks along the deeper portion of the shelf - a North American palaeogeographic setting not previously extensively sampled for macrofossils.

Book Description
“An enjoyable read that provides a substantial amount of detail on the biology, ecology, and distribution of these fantastic animals . . . Highly recommended.” —Choice More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans. It places these giants within the context of the other mammals then alive, describing their paleobiology—how they walked; how much they weighed; their diets, behavior, biomechanics; and the interactions among them and with their environment. It also tells the stories of the scientists who contributed to our discovery and knowledge of these transcendent creatures and the environment they inhabited. The episode known as the Great American Biotic Interchange, perhaps the most important of all natural history “experiments,” is also an important theme of the book, tracing the biotic events of both North and South America that led to the fauna and the ecosystems discussed in this book. “Collectively, this book brings attention to the discovery and natural history of ancient beasts in South America while providing a broader temporal and geographic background that allows readers to understand their evolution and potential immigration to South America.” —Quarterly Review of Biology “An excellent volume . . . This book is likely to facilitate progress in the understanding of fossil mammals from the Americas.” —Priscum
