The invasion of land by ocean-dwelling plants and animals was one of the most revolutionary events in the evolution of life on Earth, yet the animal invasion almost failed-twice-because of the twin mass extinctions of the Late Devonian Epoch. Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects-instead of vertebrates-might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions and the various theories proposed to explain their occurrence. Only one group of four-limbed vertebrates exists on Earth, while other tetrapod-like fishes are extinct. This gap is why the idea of "fish with feet" seems so peculiar to us, yet such animals were once a vital part of our world, and if the Devonian extinctions had not happened, members of these species, like the famous Acanthostega and Ichthyostega, might have continued to live in our rivers and lakes. Synthesizing decades of research and including a wealth of new discoveries, this accessible, comprehensive text explores the causes of the Devonian extinctions, the reasons vertebrates were so severely affected, and the potential evolution of the modern world if the extinctions had never taken place.

This book provides a wealth of geomathematical case history studies performed by the author during his career at the Ministry of Natural Resources Canada, Geological Survey of Canada (NRCan-GSC). Several of the techniques newly developed by the author and colleagues that are described in this book have become widely adopted, not only for further research by geomathematical colleagues, but by government organizations and industry worldwide. These include Weights-of-Evidence modelling, mineral resource estimation technology, trend surface analysis, automatic stratigraphic correlation and nonlinear geochemical exploration methods. The author has developed maximum likelihood methodology and spline-fitting techniques for the construction of the international numerical geologic timescale. He has introduced the application of new theory of fractals and multi fractals in the geostatistical evaluation of regional mineral resources and ore reserves and to study the spatial distribution of metals in rocks. The book also contains sections deemed important by the author but that have not been widely adopted because they require further research. These include the geometry of preferred orientations of contours and edge effects on maps, time series analysis of Quaternary retreating ice sheet related sedimentary data, estimation of first and last appearances of fossil taxa from frequency distributions of their observed first and last occurrences, tectonic reactivation along pre-existing schistosity planes in fold belts, use of the grouped jackknife method for bias reduction in geometrical extrapolations and new applications of the theory of permanent, volume-independent frequency distributions.

Quaternary of the Levant presents up-to-date research achievements from a region that displays unique interactions between the climate, the environment and human evolution. Focusing on southeast Turkey, Lebanon, Syria, Jordan and Israel, it brings together over eighty contributions from leading researchers to review 2.5 million years of environmental change and human cultural evolution. Information from prehistoric sites and palaeoanthropological studies contributing to our understanding of 'out of Africa' migrations, Neanderthals, cultures of modern humans, and the origins of agriculture are assessed within the context of glacial-interglacial cycles, marine isotope cycles, plate tectonics, geochronology, geomorphology, palaeoecology and genetics. Complemented by overview summaries that draw together the findings of each chapter, the resulting coverage is wide-ranging and cohesive. The cross-disciplinary nature of the volume makes it an invaluable resource for academics and advanced students of Quaternary science and human prehistory, as well as being an important reference for archaeologists working in the region.

Relying on the latest analytical techniques, this all-embracing new reference offers comprehensive coverage of the development, evolution, and morphology of both fossil and living cephalopods. In 34 in-depth chapters a group of 51 international neontologists and peleontologists offer and opverview of current methods, data, analyses, and interpretations, and posit suggestions for future research. With its unparalleled combination of first-rate contributions on living and fossil cephalopods, this book provides researchers and advanced students in paleontology, invertebrate zoology, evolutionary biology, and allied disciplines with a trove of recent data and authoritative interpretations that will immeasurably benefit their own studies.

This volume brings together a series of papers that address the topic of reconstructing behavior in the primate fossil record. The literature devoted to reconstructing behavior in extinct species is ovelWhelming and very diverse. Sometimes, it seems as though behavioral reconstruction is done as an afterthought in the discussion section of papers, relegated to the status of informed speculation. But recent years have seen an explosion in studies of adaptation, functional anatomy, comparative sociobiology, and development. Powerful new comparative methods are now available on the internet. At the same time, we face a rapidly growing fossil record that offers more and more information on the morphology and paleoenvironments of extinct species. Consequently, inferences of behavior in extinct species have become better grounded in comparative studies of living species and are becoming increas ingly rigorous. We offer here a series of papers that review broad issues related to reconstructing various aspects of behavior from very different types of evi dence. We hope that in so doing, the reader will gain a perspective on the various types of evidence that can be brought to bear on reconstructing behavior, the strengths and weaknesses of different approaches, and, perhaps, new approaches to the topic. We define behavior as broadly as we can including life-history traits, locomotion, diet, and social behavior, giving the authors considerable freedom in choosing what, exactly, they wish to explore."

The Holy Cross Mountains of Poland yield an abundance of marine Devonian fossils that have been studied and described since the mid-nineteenth century. Reef-formers are a major part of the overall fauna, and the stromatoporoids and the rugose corals have already received full attention. This publication extends full descriptive cover to the third of the important reef-building groups, the tabulate corals.

Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.

The field of paleoclimatology relies on physical, chemical, and biological proxies of past climate changes that have been preserved in natural archives such as glacial ice, tree rings, sediments, corals, and speleothems. Paleoclimate archives obtained through field investigations, ocean sediment coring expeditions, ice sheet coring programs, and other projects allow scientists to reconstruct climate change over much of earth's history.

When combined with computer model simulations, paleoclimatic reconstructions are used to test hypotheses about the causes of climatic change, such as greenhouse gases, solar variability, earth's orbital variations, and hydrological, oceanic, and tectonic processes. This book is a comprehensive, state-of-the art synthesis of paleoclimate research covering all geological timescales, emphasizing topics that shed light on modern trends in the earth's climate. Thomas M. Cronin discusses recent discoveries about past periods of global warmth, changes in atmospheric greenhouse gas concentrations, abrupt climate and sea-level change, natural temperature variability, and other topics directly relevant to controversies over the causes and impacts of climate change. This text is geared toward advanced undergraduate and graduate students and researchers in geology, geography, biology, glaciology, oceanography, atmospheric sciences, and climate modeling, fields that contribute to paleoclimatology. This volume can also serve as a reference for those requiring a general background on natural climate variability.

Today, we know that a mammoth is an extinct type of elephant that was covered with long fur and lived in the north country during the ice ages. But how do you figure out what a mammoth is if you have no concept of extinction, ice ages, or fossils? Long after the last mammoth died and was no longer part of the human diet, it still played a role in human life. Cultures around the world interpreted the remains of mammoths through the lens of their own worldview and mythology. When the ancient Greeks saw deposits of giant fossils, they knew they had discovered the battle fields where the gods had vanquished the Titans. When the Chinese discovered buried ivory, they knew they had found dragons' teeth. But as the Age of Reason dawned, monsters and giants gave way to the scientific method. Yet the mystery of these mighty bones remained. How did Enlightenment thinkers overcome centuries of myth and misunderstanding to reconstruct an unknown animal? The journey to unravel that puzzle begins in the 1690s with the arrival of new type of ivory on the European market bearing the exotic name "mammoth." It ends during the Napoleonic Wars with the first recovery of a frozen mammoth. The path to figuring out the mammoth was traveled by merchants, diplomats, missionaries, cranky doctors, collectors of natural wonders, Swedish POWs, Peter the Great, Ben Franklin, the inventor of hot chocolate, and even one pirate. McKay brings together dozens of original documents and illustrations, some ignored for centuries, to show how this odd assortment of characters solved the mystery of the mammoth and, in doing so, created the science of paleontology.

Jean Octave Edmond Perrier was a French zoologist who lived through the tumult of British Darwinism and Lyellism, and reminds us in this revealing account that French scientists had much to contribute to such perennial topics as evolution, catastrophism and creationism. While very much a product of the Third Republic, Perrier's account also aimed to outline timeless issues and permanent advances in taxonomic and developmental biology since classical Greece and Rome. In this aim he succeeds with surprisingly modern perspectives for a book first published in 1884. Perrier was born May 9, 1844 at Tulle, the son of the principal of a school which now bears his name, Lycee Edmond Perrier. In 1864 he was accepted to the Ecole Normale Superieure, where he was strongly influenced by Louis Pasteur and Henri de Lacaze-Duthiers. After working for three years at a high school in Agen, he obtained a post of naturalist-aid at the Museum National d'Histoire Naturelle (1868), advancing in that institution to Chair of Natural History of Molluscs, Worms and Corals (1876-1903) and then Director of the museum (1900-1919) and Chair of Comparative Anatomy (1903-1921). Previous directors of the museum included many of the scientists he discusses in this book: George Cuvier (1822-1823, 1826-1827, 1830-1831), Isidore Geoffrey St Hilaire (1860- 1861), and Alphonse Milne-Edwards (1891-1900). Perrier's own research on echinoderms and earthworms took him on several expeditions in 1880-1885, mostly to Atlantic and Mediterranean coasts, but also to the Caribbean."

Paleomagnetic field analysis occupies a separate place in the variety of studied physical parameters, since it assists us in obtaining specific stamps' of past geomagnetic field configurations. It is well-known that life on Earth and all geological-environmental processes occur in the changing geomagnetic field (the Earth's magnetic field intensity is now decreasing). Geological-geophysical records indicate that hundreds and hundreds of Earth's magnetic field reversals have occurred. Paleomagnetic research has revealed information about ancient (from hundreds to billions years ago) magnetic field changes, which reflects definite geological, archaeological, cosmological and environmental events of that time. Some geodynamic and tectonic information derived from paleomagnetic field analysis cannot be obtained by any other geophysical or geological methods. This book reveals the current understanding of leading scientists studying paleomagnetic on new approaches and results in different regions of the world. Three main issues are presented in the book: a comparison of the Earth's geomagnetic field and the Earth's biota evolution processes over the last 2.5 billion years (Chapter 1); combined paleomagnetic mapping examples of some areas of the Eastern Mediterranean (Chapter 2); various aspects of archaeomagnetic artifact examination, including advanced mathematical approach applications (Chapters 3 and 4); and utilisation of geomagnetic data from the past for historical reconstruction of China and Mesoamerica (Chapter 5). The five chapters present results of investigations of scientists from different scientific schools and demonstrate the application of various methods and approaches to analyse ancient and comparatively recent geomagnetic fields. Undoubtedly, these results are interesting both from theoretical and practical points of view. This book is intended for students of corresponding specialties, geologists, geophysicists, archaeologists and environmental scientists. This book can also be of interest to the general public interested in paleomagnetism, archaeology, geology and geophysics.

The vertebrate fossil record extends back more than 500 million years, and bonebeds--localized concentrations of the skeletal remains of vertebrate animals--help unlock the secrets of this long history. Often spectacularly preserved, bonebeds--both modern and ancient--can reveal more about life histories, ecological associations, and preservation patterns than any single skeleton or bone. For this reason, bonebeds are frequently studied by paleobiologists, geologists, and archeologists seeking to piece together the vertebrate record.
Thirteen respected researchers combine their experiences in "Bonebeds," providing readers with workable definitions, theoretical frameworks, and a compendium of modern techniques in bonebed data collection and analysis. By addressing the historical, theoretical, and practical aspects of bonebed research, this edited volume--the first of its kind--provides the background and methods that students and professionals need to explore and understand these fantastic records of ancient life and death.

Paleopalynology, second edition, provides profusely illustrated treatment of fossil palynomorphs, including spores, pollen, dinoflagellate cysts, acritarchs, chitinozoans, scolecodonts, and various microscopic fungal and algal dispersal bodies. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks.

Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. Recognizing that palynomorphs occur together in rocks because of chemical robustness and stratigraphic distribution, not biological relationship, the central sections are organized stratigraphically. Among many other topics presented are the sedimentation and geothermal alteration of palynomorphs, and palynofacies analysis. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.

This work is a detailed study of people and plants in Little Dixie, a seven-county region of central Missouri. Based on three summers of field research, Professor Nolan combines ethnoscience with folklore to document what and why people know about wild plants in this little-known section of the American Midwest. The book is organized around the cognitive and behavioral differences between local experts and 'novices' who gather wild plant foods and medicines regularly throughout the seasons in Little Dixie. Ethnobotanical knowledge is described as an ongoing interaction between ecology and cognition, under constant modification by shifting cultural beliefs about edibility, efficacy, and sensory appeal. As consumable resources and symbols of belonging, wild plants are detailed with ethnographic context and vivid pen-and-ink sketches. Wild Harvest in the Heartland will appeal to a broad audience of anthropologists, ethnobotanists, folklorists, and ecologists, and will provide a welcome resource for naturalists, conservationists, and outdoor enthusiasts.

The first book to approach the Cretaceous extinction -- the period during which dinosaurs disappeared from Earth -- from the perspective of the fossil record.

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.

The plant fossil record provides evidence that the genus Metasequoia was widely distributed and experienced a wide range of climatic and environmental conditions throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus is limited to one species with approximately 5,000 mature individuals growing in the Xiahoe Valley in southeastern China. This book is a distillation of the collective efforts and results of the worlda (TM)s Metasequoia specialists and enthusiasts. It is the most up-to-date and comprehensive reference source for the genus and the authors have sought to incorporate obscure, hard-to-get and non-English reference sources. The book reviews what is known about the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

This book presents a definitive overview of fossil and living Metasequoia and was written by sixteen of the worlda (TM)s experts on this important genus. Given the reality of increasing human pressure and the inevitability of global change, efforts to conserve this ancient genus are underway. This book will be of interest to botanists, geologists, paleobotanists, biogeographers, foresters, ecologists, paleoecologists, ecophysiologists, geochemists, climate modelers, geneticists, naturalists, science historians, and gardeners and will be useful as a supplemental text for advanced undergraduate and graduate level courses in paleoecology.

Our knowledge of extinct animals depends almost entirely upon the study of fossils. This richly illustrated book clothes the skeletons of dinosaurs and other Mesozoic reptiles with flesh, and shows how these fascinating animals evolved and probably lived. Expert author John L. Cloudsley-Thompson provides an interesting synthesis of current views on their ecology, physiology and behaviour, and outlines the various hypotheses that have been proposed to explain their extinction. Numerous beautiful drawings of the animals and their environment illustrate this exciting monograph.

This book focuses on the first vertebrates to conquer land and their long journey to become fully independent from the water. It traces the origin of tetrapod features and tries to explain how and why they transformed into organs that permit life on land. Although the major frame of the topic lies in the past 370 million years and necessarily deals with many fossils, it is far from restricted to paleontology. The aim is to achieve a comprehensive picture of amphibian evolution. It focuses on major questions in current paleobiology: how diverse were the early tetrapods? In which environments did they live, and how did they come to be preserved? What do we know about the soft body of extinct amphibians, and what does that tell us about the evolution of crucial organs during the transition to land? How did early amphibians develop and grow, and which were the major factors of their evolution? The Topics in Paleobiology Series is published in collaboration with the Palaeontological Association, and is edited by Professor Mike Benton, University of Bristol. Books in the series provide a summary of the current state of knowledge, a trusted route into the primary literature, and will act as pointers for future directions for research. As well as volumes on individual groups, the series will also deal with topics that have a cross-cutting relevance, such as the evolution of significant ecosystems, particular key times and events in the history of life, climate change, and the application of a new techniques such as molecular palaeontology. The books are written by leading international experts and will be pitched at a level suitable for advanced undergraduates, postgraduates, and researchers in both the paleontological and biological sciences.
