Book Description
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. Originally published in 1992. 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 Late Eocene and the Eocene-Oligocene (E-O) transition mark the most profound oceanographic and climatic changes of the past 50 million years of Earth history, with cooling beginning in the middle Eocene and culminating in the major earliest Oligocene Oi-1 isotopic event. The Late Eocene is characterized by an accelerated global cooling, with a sharp temperature drop near the E-O boundary, and significant stepwise floral and faunal turnovers. These global climate changes are commonly attributed to the expansion of the Antarctic ice cap following its gradual isolation from other continental masses. However, multiple extraterrestrial bolide impacts, possibly related to a comet shower that lasted more than 2 million years, may have played an important role in deteriorating the global climate at that time. This book provides an up-to-date review of what happened on Earth at the end of the Eocene Epoch.

Book Description
This volume focuses on the reconstruction of past ecosystems and provides a comprehensive review of current techniques and their application in exemplar studies. The 18 chapters address a wide variety of topics that span vertebrate paleobiology and paleoecology (body mass, postcranial functional morphology, evolutionary dental morphology, microwear and mesowear, ecomorphology, mammal community structure analysis), contextual paleoenvironmental studies (paleosols and sedimentology, ichnofossils, pollen, phytoliths, plant macrofossils), and special techniques (bone microstructure, biomineral isotopes, inorganic isotopes, 3-D morphometrics, and ecometric modeling). A final chapter discusses how to integrate results of these studies with taphonomic data in order to more accurately characterize an ancient ecosystem. Current investigators, advanced undergraduates, and graduate students interested in the field of paleoecology will find this book immensely useful. The length and structure of the volume also makes it suitable for teaching a college-level course on reconstructing Cenozoic ecosystems.

Book Description
A student-friendly textbook that describes ancient soils, how they may be identified, and their use in paleoenvironmental reconstruction Ancient soils contain vital mineralogical, geochemical, textural, and paleontological information about the continental environments in which they formed. Advances in isotope geochemistry and sequence-stratigraphic models allow evermore detailed reconstructions of environmental change from paleosols, and new insights into such diverse topics as atmospheric chemistry, global change, paleoecology, geobiology and mass extinction. This book educates readers about the field of paleopedology and how it remains a key area of investigation for geologists and environmental scientists seeking to learn about, and reconstruct, the condition and evolution of paleoenvironments. Presented in three sections—Soils and Palesols; Factors in Soil Formation; and Fossil Record of Soils—Soils of the Past: An Introduction to Paleopedology describes the main types of ancient soil, procedures for identifying and studying them, their classification and, most significantly, a wide array of examples of how paleosols have been used for paleoenvironmental reconstruction. The book is an excellent reflection of the current state of knowledge and can be widely adopted over many disciplines. All chapters have been revised and updated to reflect advances in soil science in the last two decades New tables display a wealth of new data added since the 2nd edition published in 2001 New figures have been added and line art has been redrawn to improve clarity and promote understanding References have been updated throughout Soils of the Past, 3rd Edition is written for advanced undergraduates studying paleopedology as part of a degree in geology, environmental science, or physical geography, and for interested professional earth scientists.

Book Description
This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.

Book Description
Presents and authoritative and biblical geological time-line for high school students and adults. Includes substantial illustrations, a glossary, and an extensive reference section. Clearly explains how data from volcanic deposits, seismic activity in Earth history, and even the presence of ripple marks in rock layers support the Bible as history. From the acclaimed Creation Research Society, this technical study of rock strata, and the fossils found therein, gives a solidly scientific rationale for believing in a young earth. This advanced guide is ideal for upper-level homeschool students, college students, or anyone wishing to explore this fascinating subject in-depth and includes questions for review at the end of each chapter. Froede presents a credible geological time-line and explains the formation and existence of fossil layers in rock sediments around the world.
