A classic work from the Yale Peabody Museum of Natural History describing the mosasaurs, a group of large predatory marine lizards of the Mesozoic Mosasaurs have captured the imagination of readers everywhere interested in prehistoric life, and they remain a focus of paleontological study to this day. This edition of Dale Russell's Systematics and Morphology of American Mosasaurs presents the complete, classic text, generously illustrated with more than one hundred drawings and photographs, and includes a new foreword by vertebrate paleontologist Jacques A. Gauthier (Yale University and Yale Peabody Museum of Natural History). Distributed for the Yale Peabody Museum of Natural History

Earth's climate has undergone dramatic changes over the geologic timescale. At one extreme, Earth has been glaciated from the poles to the equator for periods that may have lasted millions of years. At another, temperatures were once so warm that the Canadian Arctic was heavily forested and large dinosaurs lived on Antarctica. Paleoclimatology is the study of such changes and their causes. Studying Earth's long-term climate history gives scientists vital clues about anthropogenic global warming and how climate is affected by human endeavor.

In this book, Michael Bender, an internationally recognized authority on paleoclimate, provides a concise, comprehensive, and sophisticated introduction to the subject. After briefly describing the major periods in Earth history to provide geologic context, he discusses controls on climate and how the record of past climate is determined. The heart of the book then proceeds chronologically, introducing the history of climate changes over millions of years--its patterns and major transitions, and why average global temperature has varied so much. The book ends with a discussion of the Holocene (the past 10,000 years) and by putting manmade climate change in the context of paleoclimate.

The most up-to-date overview on the subject, "Paleoclimate" provides an ideal introduction to undergraduates, nonspecialist scientists, and general readers with a scientific background.

This is a personal account of the human side of Everett C Olson's distinguished career as a palaeobiologist. Origins and the combination of events that led to a formal education at the University of Chicago, the selection of a career, and an interest in the Permian are reviewed. Then Olson vividly describes two decades of field work in Texas, emphasising the people, places and events that he and his co-workers encountered there at mid-century. The second half of the book is devoted to Olson's pioneering efforts in establishing and strengthening ties between palaeontologists of the US and USSR during the Cold War years and especially his deepening friendship with Professor Ivan A Efremov. Olson and Efremov, two scientists from different cultures, wrestled with opposing philosophies but shared common interests and emotions. This book will certainly be of interest to the many people who have known Dr Olson as colleague, mentor, and friend. For the general reader, the book provides insights into the career of a distinguished contemporary scientist and represents an important chapter in the 20th century history of palaeontology, earth science, and international scientific relations.
