In order to understand the state of the oceans, researchers turn to the origins of global waters, 90 million years ago. This study explores the subject of sea-level change in the Phanerozoic era, a topic which has much relevance to current issues of climatic shifts and the greenhouse effect.

This monograph contains over fifty high-quality plates of electron micrographs of limestones. It spans the field of limestones in age from Cambrian to Recent, and in type from deep-sea oozes to intertidal rocks. It represents the outcome of four years of research in the new field of electron microscopy applied to rocks. The illustrations show the spectacular results and much more is revealed in fossils and textures than would be expected on the basis of optical studies. Originally published in 1967. 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.

Here is a new edition of a widely acclaimed account of the most celebrated controversies in the history of geology--a book that covers many of the most important ideas that have emerged since the birth of the science. Among the great debates described here are those involving catastrophe theory, uniformitarianism, the discovery of the Ice Age, speculation concerning the age of the earth, and the advent of new ideas on plate tectonics and continental drift. In presenting these key topics, the author opens the fascinating history of geology to a wide audience. Frequently citing original sources, the author gives readers a sense of the colorful and at times immensely entertaining language of scientific discourse. This edition includes a new chapter on the emergence of stratigraphy in the nineteenth century, focusing on controversies surrounding the Cambrian-Silurian and Devonian. Another new chapter reviews the mass extinction theory, which is still hotly debated. Other chapters have been revised to reflect recent developments and changes in the field. Authoritative and highly readable, this unique work will interest all readers interested in the history of science and especially the origin of the prevailing ideas in geology today.

Probably no extinct mammal can be studied in more detail, from a fuller fossil record, than the Cave Bear, Ursius Spelaeus. In his delightful, award-winning portrait, renowned finnish paleontologist Bjorn Kurten takes readers on a tour of cave bear life in the ice age. The Cave Bear story conveys the facts about these largest of bears, including the habits and society of Cave Bears, their ice age environment, biological variations, and extinction. Kurten also details the relationship between man and bear - namely, the theories surrounding bear-hunting and Cave Bear cults. Complete with brilliant illustrations by Margaret Lambert Newman that show restoration scenes of the ice age and its vanished animals, the Cave Bear story not only represents the authoritative work of an eminent paleontologist but remains accessible to any reader with an interest in the rich prehistory of our planet.

In the 19th and early 20th centuries, North American and European governments generously funded the discoveries of such famous paleontologists and geologists as Henry de la Beche, William Buckland, Richard Owen, Thomas Hawkins, Edward Drinker Cope, O. C. Marsh, and Charles W. Gilmore. In Patrons of Paleontology, Jane Davidson explores the motivation behind this rush to fund exploration, arguing that eagerness to discover strategic resources like coal deposits was further fueled by patrons who had a genuine passion for paleontology and the fascinating creatures that were being unearthed. These early decades of government support shaped the way the discipline grew, creating practices and enabling discoveries that continue to affect paleontology today.

Simone Marchi presents the emerging story of how cosmic collisions shaped both the solar system and our own planet, from the creation of the Moon to influencing the evolution of life on Earth. The Earth emerged out of the upheaval and chaos of massive collisions in the infancy of the Solar System, more than four billion years ago. The largest of these events sent into orbit a spray of molten rocks out of which the Moon coalesced. As in ancient mythological tales, this giant catastrophe marks the birth of our planet as we know it. Space exploration has shown that signs of ancient collisions are widespread in the Solar System, from the barren and once-habitable Mars to the rugged asteroids. On Earth these signs are more subtle, but still cataclysmic, such as the massive asteroid strike which likely sparked the demise of the dinosaurs and many other forms of life some 66 million years ago. Signatures of even more dramatic catastrophes are concealed in ancient rocks. These events wreaked havoc on our planet's surface, influencing global climate and topography, while also enriching the Earth with gold and other rare elements. And recently, modern science is finding that they could even have contributed to developing the conditions conducive to life. In Colliding Worlds, Simone Marchi explores the key role that collisions in space have played in the formation and evolution of our solar system, the development of planets, and possibly even the origin of life on Earth. Analysing our latest understanding of the surfaces of Mars and Venus, gleaned from recent space missions, Marchi presents the dramatic story of cosmic collisions and their legacies.

From the outback of Australia to the Gobi Desert of Mongolia and the savanna of Madagascar, the award-winning science writer and dinosaur enthusiast John Pickrell embarks on a world tour of new finds, meeting the fossil hunters who work at the frontier of discovery. He reveals the dwarf dinosaurs unearthed by an eccentric Transylvanian baron; an aquatic, crocodile-snouted carnivore bigger than T. rex that once lurked in North African waterways; a Chinese dinosaur with wings like a bat; and a Patagonian sauropod so enormous it weighed more than two commercial jet airliners. Other surprising discoveries hail from Alaska, Siberia, Canada, Burma, and South Africa. Why did dinosaurs grow so huge? How did they spread across the world? Did they all have feathers? What do sauropods have in common with 1950s vacuum cleaners? The stuff of adventure movies and scientific revolutions, Weird Dinosaurs examines the latest breakthroughs and new technologies that are radically transforming our understanding of the distant past. Pickrell opens a vivid portal to a brand-new age of fossil discovery, in which fossil hunters are routinely redefining what we know and how we think about prehistory's most iconic and fascinating creatures.

In 1878, the first complete dinosaur skeleton was discovered in a coal mine in Bernissart, Belgium. Iguanodon, first described by Gideon Mantell on the basis of fragments discovered in England in 1824, was initially reconstructed as an iguana-like reptile or a heavily built, horned quadruped. However, the Bernissart skeleton changed all that. The animal was displayed in an upright posture similar to a kangaroo, and later with its tail off the ground like the dinosaur we know of today. Focusing on the Bernissant discoveries, this book presents the latest research on Iguanodon and other denizens of the Cretaceous ecosystems of Europe, Asia, and Africa. Pascal Godefroit and contributors consider the Bernissart locality itself and the new research programs that are underway there. The book also presents a systematic revision of Iguanodon; new material from Spain, Romania, China, and Kazakhstan; studies of other Early Cretaceous terrestrial ecosystems; and examinations of Cretaceous vertebrate faunas. -- Indiana University Press

Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.

Described as 'a writer in the tradition of Henry David Thoreau, John Muir, and other self-educated seers' by the "San Francisco Chronicle", David Rains Wallace turns his attention in this new book to another distinctive corner of California - its desert, the driest and hottest environment in North America. Drawing from his frequent forays to Death Valley, Red Rock Canyon, Kelso Dunes, and other locales, Wallace illuminates the desert's intriguing flora and fauna as he explores a controversial, unresolved scientific debate about the origin and evolution of its unusual ecosystems. Eminent scientists and scholars appear throughout these pages, including maverick paleobiologist Daniel Axelrod, botanist Ledyard Stebbins, and naturalists Edmund Jaeger and Joseph Wood Krutch. Weaving together ecology, geology, natural history, and mythology in his characteristically eloquent voice, Wallace reveals that there is more to this starkly beautiful landscape than meets the eye.

Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out--a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.

"[An] extraordinary book. . . . Mr. Gould is an exceptional combination of scientist and science writer. . . . He is thus exceptionally well placed to tell these stories, and he tells them with fervor and intelligence."—James Gleick, New York Times Book Review

High in the Canadian Rockies is a small limestone quarry formed 530 million years ago called the Burgess Shale. It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

"Gould at his best. . . . The message of history is superbly conveyed. . . . Recommended reading for scientists and nonscientists of all persuasions."—Walter C. Sweet, Science

"Luminous. . . . Filled with profound and upsetting ideas like the Burgess Shale itself and just as solid. It is surely one of nature's best stories, told with a light touch by a master of the field."—Lewis Thomas, M.D.

"There is no question about the historical importance of the Burgess Shale, and Gould is right when he says that it deserves a place in the public consciousness along with big bangs and black holes. . . . A compelling story, told with characteristic verve."—Richard A. Fortey, Nature

Human life, and how we came to be, is one of the greatest scientific and philosophical questions of our time. This compact and accessible book presents a modern view of human evolution. Written by a leading authority, it lucidly and engagingly explains not only the evolutionary process, but the technologies currently used to unravel the evolutionary past and emergence of Homo sapiens. By separating the history of palaeoanthropology from current interpretation of the human fossil record, it lays numerous misconceptions to rest, and demonstrates that human evolution has been far from the linear struggle from primitiveness to perfection that we've been led to believe. It also presents a coherent scenario for how Homo sapiens contrived to cross a formidable cognitive barrier to become an extraordinary and unprecedented thinking creature. Elegantly illustrated, Understanding Human Evolution is for anyone interested in the complex and tangled story of how we came to be.
