Book Description
>The rich fossil record of the Atlantic and Gulf coastal plains of the United States is a gold mine for interested scientists. The last thirty million years of Earth history are superbly chronicled by a succession of fossil assemblages extending from the St. Lawrence River to Florida. Marine scientists, paleontologists, and systematic biologists al

Book Description
How were the tropical Americas formed? This ambitious volume draws on extensive, multidisciplinary research to develop new views of the geological formation of the isthmus linking North and South America and of the major environmental changes that reshaped the Neotropics to create its present-day marine and terrestrial ecosystems. Recent discoveries show that dramatic changes in climate and ocean circulation can occur very quickly, and that ecological communities respond just as rapidly. Abrupt changes in the composition of fossil assemblages, formerly dismissed as artifacts of a poor fossil record, now are seen as accurate records of swift changes in the composition of ocean communities. The twenty-four contributors use current work in paleontology, geology, oceanography, anthropology, ecology, and evolution to paint this challenging portrait of rapid environmental and evolutionary change. Their conclusions argue for a revision of existing interpretations of the fossil record and the processes—including invading Eurasian peoples—that have produced it.

Book Description
Representing the state of the art in evolutionary paleobiology, this book provides a much-needed overview of this rapidly changing field. An influx of ideas and techniques both from other areas of biology and from within paleobiology itself have resulted in numerous recent advances, including increased recognition of the relationships between ecological and evolutionary theory, renewed vigor in the study of ecological communities over geologic timescales, increased understanding of biogeographical patterns, and new mathematical approaches to studying the form and structure of plants and animals. Contributors to this volume—a veritable who's who of eminent researchers—present the results of original research and new theoretical developments, and provide directions for future studies. Individually wide ranging, these papers all share a debt to the work of James W. Valentine, one of the founders of modern evolutionary paleobiology. This volume's unified approach to the study of life on earth will be a major contribution to paleobiology, evolution, and ecology.

Book Description
One of the most important questions we can ask about life is "Does ecology matter?" Most biologists and paleontologists are trained to answer "yes," but the exact mechanisms by which ecology matters in the context of patterns that play out over millions of years have never been entirely clear. This book examines these mechanisms and looks at how ancient environments affected evolution, focusing on long-term macroevolutionary changes as seen in the fossil record. Evolutionary paleoecology is not a new discipline. Beginning with Darwin, researchers have attempted to understand how the environment has affected evolutionary history. But as we learn more about these patterns, the search for a new synthetic view of the evolutionary process that integrates species evolution, ecology, and mass extinctions becomes ever more pressing. The present volume is a benchmark sampler of active research in this ever more active field.

Book Description
The authors have synthesized 16 years of geological and geophysical studies which document an 85-km-wide impact crater buried 500 m beneath Chesapeake Bay in south eastern Virginia, USA. In doing so, they have integrated extensive seismic reflection profiling and deep core drilling to analyze the structure, morphology, gravimetrics, sedimentology, petrology, geochemistry, and paleontology of this submarine structure. Of special interest are a detailed comparison with other terrestrial and extraterrestrial craters, as well as a conceptual model and computer simulation of the impact. The extensive illustrations encompass more than 150 line drawings and core photographs.
