This book presents current knowledge of the early vertebrates--mainly fish, but including some terrestrial creatures--which lived about 250 to 470 million years ago. The work focuses on anatomical and phylogenetic questions, but includes information on fossil discovery and preparation, as well as the analysis of the characteristics from which their relationships may be reconstructed. The author addresses both new and old problems in the evolution of certain anatomical details and deals briefly with the animals' way of life, extinction, and former distribution. The book is the first in its field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram of relationships, or cladogram, with a selection of characters at each node, and a succinct phylogenetic classification.

Most nonscientists are usually aware of fossils, and it is commonly believed that they are extremely rare. In fact, fossils are exceptionally common in many sedimentary rocks and are used extensively in geology for age dating, interpretation of ancient environments, and the discovery of natural resources. However, there is another type of fossil deposit that is truly rare. These rare fossil deposits, called Lagerst?tten, preserve the remains of the soft tissues or the articulated skeletal remains of ancient creatures in truly astonishing fine detail. Some of these deposits are world-famous, such as the Burgess Shale, or Solnhofen but there are others dating from many different geological eras from the Paleozoic, up to the Eocene. Recently, a concerted effort has been made to understand the overall significance of these rare fossil deposits. Whereas in the past these deposits were considered novelties, modern researchers are trying to understand what they can tell us about ancient life and environments. New sophisticated techniques (including image and geochemical analyses) are providing enormous new contributions to our knowledge of Lagerst?tten sites and to paleobiology in general.

This volume describes many of the most famous Lagerst?tten locations worldwide and is complete with over 70 superb halftones showing some of these exotic fossils in all their glory. Paleontologists are beginning to understand why such deposits occur, how they have varied since the advent of marine metazoan life, and how their presence effects our understanding of the evolution of life in the Earth's oceans. In this way, the study of Lagerst?tten continues to move towards the mainstream of paleobiological, biological, and geological research, and away from its former status as the examination of mere curiosities.

All those interested in these beautiful and sometimes enigmatic deposits will want to own this book.

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.

Fossils have been vital to our understanding of the formation of the earth and the origins of all life on it. However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this delightful book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are 'living fossils'? What fossils will we leave behind for future generations to examine? Building on the scientific aspects, he places fossils in a very human context, highlighting their impact on philosophy and mythology, our concept of time, and today's popular culture. What quickly becomes obvious is that the discovery of fossils and the ways in which they have been interpreted over time makes for fascinating reading. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination.

This is the official guide to Benjamin Waterhouse Hawkins' sculptures at Crystal Palace, Sydenham, including dinosaurs and other monsters. Owen's guide offers technical descriptions of their biology and geology.

The long and distinguished tradition of tracking dinosaurs and other extinct animals in Europe dates back to the 1830s. Yet this venerable tradition of scientific activity cannot compare in magnitude and scope with the unprecedented spate of discovery and documentation of the last few years. Now, following on the heels of his "Dinosaur Tracks and Other Fossil Footprints of the Western United States, " Martin Lockley teams up with Christian Meyer to present an up to date synthesis of the recent findings in the field of European fossil footprints. Drawing extensively on their own research results from studies in Britain, Switzerland, Portugal, Spain, and elsewhere, the authors create a dynamic picture of mammal, reptile, bird, and amphibian "track-makers" throughout more than 300 million years of vertebrate evolution, placed in the context of Europe's changing ancient environments.

Beginning with an introduction to tracking and a history of the European tracking tradition, "Dinosaur Tracks and Other Fossil Footprints of Europe" then charts a broad path of evolutionary proliferation from the proto-dinosaurs of the Early Triassic period to the dinosaurs' decline and disappearance in the Upper Cretaceous. The survey continues into the age of mammals and birds, ending with the cave art of our Paleolithic ancestors.

This book, proposed as a companion volume to Professor Holman's Pleistocene Amphibians and Reptiles in North America (OUP 1995), presents, in detail, occurences of the herpetofauna in Britain and Western and Central Europe as well as discussions on the paleogeography, paleoecology, and evolution of these groups. The format follows in general that of the volume on North America, starting with an overview of the Pleistocene in Europe followed by a bestiary and chapters on identification of fossils, sites yielding fossils, range adjustments, evolutionary and extinction patterns, and origins of modern herpetofauna in Europe.

This beautiful volume introduces the incredible animals that populated the planet before the Age of the Dinosaurs. Readers voyage to a time, beginning about 370 million years ago, when the first four-footed vertebrates appeared, and ending 200 million years later at the moment when the dinosaurs begin their ascent. During this time, vertebrates emerge from the sea and there appears a parade of animals, each more astonishing than the last. On this expedition, we learn how paleontologists become detectives to understand the history of life and we discover that many widely held ideas about the evolution of species are completely false. Earth before the Dinosaurs is an entertaining and informative guide to an astonishing and little-known world.

There are few stories more remarkable than the evolution of life on earth. This Very Short Introduction presents a succinct guide to the key episodes in that story - from the very origins of life four million years ago to the extraordinary diversity of species around the globe today. Beginning with an explanation of the controversies surrounding the birth of life itself, each following chapter tells of a major breakthrough that made new forms of life possible: including sex and multicellularity, hard skeletons, and the move to land. Along the way, we witness the greatest mass extinction, the first forests, the rise of modern ecosystems, and, most recently, conscious humans. Introducing ideas from a range of scientific disciplines, from evolutionary biology and earth history, to geochemistry, palaeontology, and systematics, Michael Benton explains how modern science pieces the evidence in this vast evolutionary puzzle together, to build up an accessible and up-to-date picture of the key developments in the history of life on earth.

Paleoecology is a discipline that uses evidence from fossils to provide an understanding of ancient environments and the ecological history of life through geological time. This text covers the fundamental approaches that have provided the foundation for present paleoecological understanding, and outlines new research areas in paleoecology for managing future environmental and ecological change. Topics include the use of actualism in paleoecology, development of paleoecological models for paleoenvironmental reconstruction, taphonomy and exceptional fossil preservation, evolutionary paleoecology and ecological change through time, and conservation paleoecology. Data from studies of invertebrates, vertebrates, plants and microfossils, with added emphasis on bioturbation and microbial sedimentary structures, are discussed. Examples from marine and terrestrial environments are covered, with a particular focus on periods of great ecological change, such as the Precambrian-Cambrian transition and intervals of mass extinction. Readership: This book is designed for advanced undergraduates and beginning graduate students in the earth and biological sciences, as well as researchers and applied scientists in a range of related disciplines.

The first book to review all the evidence concerning both the dinosaur extinctions and all the other major extinctions - of plant, animal, terrestrial, and marine life - in the history of life. It critically assess all the possible mass extinction mechanisms, including meteorite impact, anoxia, and volcanism.

In this illustrated work, Kurt?n offers a vivid panorama of vertebrate animal life as it unfolded during the more than three million years before humans came to the New World.

Based on two decades of research, The Late Devonian Mass Extinction reviews the many theories that have been presented to explain the global mass extinction that struck the earth over 367 million years ago, considering in particular the possibility that the extinction was triggered by multiple impacts of extraterrestrial objects.

This book is a unique collection of evolutionary and ecological perspectives in the study of biodiversity by some of the leading researchers in the field. The seventeen chapters are divided into three sections, each section beginning with an overview of its contents. The book traces past landmarks, current questions, and future trends in biodiversity reseach ranging from the evaluation of the fossil record and molecular phylogenies in untangling the genesis of diversity; to population, community, and ecosystem-level approaches in understanding patterns of species persistence; and finally to large-scale diversity patterns and species conservation. Subject reviews, case-studies, and discussions of techniques are combined to produce a state-of-the-art book.

Palaves biogeographic research over the last twenty years or so has been galvarized by the general acceptance of plate tectonics and, hence, of the orrurrence of continental drift. This study, written by an internationally respected author of palaeontological books from student to professional levels, is the first to synthesize this research.

The introductory chapters deal with the historical background, the major factors influencing the distribution of organisms, methods of biogeographic analysis, and the major events of the Phanerozoic. These are followed by concise reviews of the changing terrestrial and marine biogeographic patterns, as indicated by the fossil record, over successive eras, and an attempt to explain the patterns observed. The comprehensive bibliography provided allows readers to follow up material in greater depth.

the book is a concise overview of a large body of material, presented in a manner that will be accessible to students and teachers of palaeontology who are interested in biogeography, to geologists who need to know more about the use of fossils in tectonic reconstructions, and to biologists requiring historical insights into the distributions of living organisms.

As the need increases for sound estimates of impending rates of animal and plant species extinction, scientists must have a firm grounding in the qualitative and quantitative methods required to make the best possible predictions. Extinction Rates offers the most wide-ranging and practical introduction to those methods available. With contributions from an international cast of leading experts, the book combines cutting-edge information on recent and past extinction rates with treatments of underlying ecological and evolutionary causes. Throughout, it highlights apparent differences in extinction rates among taxonomic groups and places, aiming to identify unresolved issues and important questions. Written with advanced undergraduate and graduate students in mind, Extinction Rates will also prove invaluable to researchers in ecology, conservation biology, and the earth and environmental sciences.

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.

A photographic guide to Oklahoma's Devonian trilobites. The geological history of Coal County, Oklahoma. Descriptions of rock formations where trilobites are found. Excavation and restoration of trilobites. A photographic atlas of the Lower Devonian trilobites of Oklahoma, with helpful information to aid in their identification.

Trilobites are a well-known fossil group, possibly second most famous only to dinosaurs. With their easily fossilized exoskeleton, they left an extensive and diverse fossil record. They began a drawn-out decline to extinction during Late Devonian time, when all but one of the trilobite orders died out.

This meticulously researched reference guide is a photographic atlas and descriptive compendium on the trilobites of Coal County, Oklahoma. The species described lived during the Lower Devonian in a shallow tropical ocean that had advanced over the landscape of North America. More than twenty species are exquisitely preserved in Oklahoma's limestone rocks.

Each species is carefully illustrated, including thorough descriptions, so that those familiar and unfamiliar can understand and appreciate these amazing creatures. The most current scientific research on these trilobites is also included. For those wishing to pursue a deeper interest in trilobites, a comprehensive bibliography lists hundreds of sources of information for further study.

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.
