Carbonate depositional systems in the Paleozoic geologic time represent fewer studies in paleoecological interactions than the siliciclastic systems. To evaluate this difference, the paleontology of the Middle Devonian Dundee Formation in Ohio has been explored. This geologic formation represents an important environment in the Michigan Basin of North America. Understanding biotic relationships such as mutualism, commensalism, parasitism and predation in an ecological community is important in unraveling the mystery of the fossil record. This research has contributed a large field collection which will be useful in documenting the fossil content of this unit for future workers. Rituparna Bose used new microscopic and imaging techniques in qualitatively analyzing the biotic interactions in small invertebrate shells. More importantly, she solved complex hypotheses in newly emerging problems in the field of geology and paleontology, such as the biodiversity crisis. Her study involved exploring the Devonian geology and paleontology of a geologic formation of a new unexplored quarry in Ohio, namely the Whitehouse Quarry in Lucas County, Ohio. She identified Devonian brachiopods to the genus level based on their morphology, and diagnosed paleoecological entities on host brachiopods and further measured episkeletobiont traces on hosts to understand the effects of environment and evolution on extinct species. Such studies have implications in predicting future biodiversity, ecosystem conservation and climate change. This research will also assist future workers to compare the ecology of brachiopod hosts of the Dundee Limestone with that of other Devonian brachiopods, from both carbonate and siliciclastic settings.

Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of Oland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil.

Palaeobiogeography is a complex subject which processes information provided by both Biology and Earth Sciences. It is conceptually and philosophically equivalent to neobiogeography. Nevertheless, its methods are somewhat different, since it is limited by the incompleteness of the fossil record. On the other hand, it has direct access to the time dimension, a key ingredient of organic evolution. Mesozoic benthonic mollusks, and especially bivalves, have a great potential for palaeobiogeographical analysis due to their commonly good preservation, abundance, diversity and high dispersion potential at the larval stage. From a merely descriptive point of view, the analysis of their distribution shows latitudinal gradients and distributional patterns, both at regional and global scales, which are the basis for the recognition of biochoremas or palaeobiogeographical units of different ranks. Moving forward towards a causal
palaeobiogeography, these organisms also provide interesting insight into particular biogeographical questions, such as bipolarity and its origin. The evolution in time of the
recognized biochoremas can be discussed in relation to palaeoclimas and extinction events. Finally, some of the results obtained from the analysis of the distribution of past
bivalve biotas were even used to propose and discuss the development of marine corridors and argue about the distribution of continents in the past.

This book discusses how and why animals evolved into particular shapes. The book identifies the physical laws which decide over the evolutionary (selective) value of body shape and morphological characters. Comparing the mechanical necessities with morphological details, the author attempts to understand how evolution works, and which sorts of limitations are set by selection. The book explains morphological traits in more biomechanical detail without getting lost in physics, or in methods. Most emphasis is placed on the proximate question, namely the identification of the mechanical stresses which must be sustained by the respective body parts, when they move the body or its parts against resistance. In the first part of the book the focus is on 'primitive' animals and later on the emphasis shifts to highly specialized mammals. Readers will learn more about living and fossil animals. A section of the book is dedicated to human evolution but not to produce another evolutionary tree, nor to refine a former one, but to contribute to answering the question: "WHY early humans have developed their particular body shape".

The transition from the Paleocene to the Eocene Epoch -- approximately 55 million years ago -- represents a critical moment in the earth's history, when the warmest climatic episode of the Cenozoic era occurred. This sudden global warming resulted in major turnovers among marine and terrestrial organisms. Although this episode has become one of the most popular areas of research in the geologic sciences in the past decade, there has not yet been a work that brings together the profusion of new results in one volume. This book offers by far the most comprehensive source of data on a critically important interval of the earth's history.

The editors have brought together the finest scholars working today on the Paleocene-Eocene transition. Covering mammals, reptiles, invertebrates, and plants, as well as the spectrum of marine biotas, the book documents both the well-established and the lesser-known turnovers, such as those of the calcareous nannoplankton and terrestrial mollusks. The volume is also notable for its integration of knowledge culled from a wide variety of disciplines, geographic settings, fossil groups, and paleoenvironments.

With 21 contributions and more than 180 illustrations, this book will be of great value as a reference source for a wide spectrum of scientists, from marine geologists and oceanographers to paleontologists, paleoclimatologists, and stratigraphers.

What light do fossils shed on the deep history of life's most diverse phylum, the Arthropoda? Are the interrelationships between major groups of arthropods -- crustaceans, chelicerates, and tracheates -- resolved the same way whether or not fossils are included? How should we combine evidence from extinct and extant taxa? These are the central questions of "Arthropod Fossils and Phylogeny."

Many recent controversies in arthropod evolution have been initiated by new fossil discoveries and new interpretations of early fossils. This book examines the role that these finds and ideas have played in understanding the deep evolutionary history of arthropods. The authors of the book's seven chapters have been at the forefront of this research.

Contributions include phylogeny based on DNA sequence data for living groups, cladistic analysis of the major lineages of arthropods, detailed case studies of crustaceans, chelicerates, and lobopodians, and the evolutionary significance of arthropods in Cambrian fossil sites with exceptional preservation. All contributors use cladistic methods, presenting copious new data to stimulate further research.

The book will be a vital resource for paleontologists, researchers on extant arthropods interested in fossil history, and evolutionists concerned with how different kinds of systematic data should be analyzed.

There is, broad agreement in the scientific world today that all humans share common origins in Africa, but when Charles Darwin first suggested it in 1871, few European scientists took his theory seriously. When the Taung child skull was found in South Africa in 1924, Raymond Dart supported Darwin’s theory, but it did little to shift scientific opinion. In the 1980s, when genetics research concluded that all living humans can trace their maternal ancestry back to Africa 200 000 years ago, many international scientists were slow to accept this claim. Scientists, and their research, are often shaped by the prevailing social and political context at the time. Kuljian explores this trend in South Africa and provides fresh insight on the search for human origins – in the fields of palaeoanthropology and genetics – over the past century. The book follows the colonial practice in Europe, the US and South Africa of collecting human skeletons and cataloguing them into racial types, in the hope that they would provide clues to human evolution. Kuljian sheds light on how, during apartheid, the concept of racial classification mirrored the way in which many scientists thought about race and human evolution. In more recent years, the field has been shaped by a more open and diverse approach, and more women and African scientists are entering the field. Research continues and new information is gathered all the time. Darwin’s Hunch also examines current developments in the search for human origins, and uncovers stories that shed new light on the past.

This detailed exposition gives background and context to how modern biogeography has got to where it is now. For biogeographers and other researchers interested in biodiversity and the evolution of life on islands, Biogeology: Evolution in a Changing Landscape provides an overview of a large swathe of the globe encompassing Wallacea and the western Pacific. The book contains the full text of the original article explored in each chapter, presented as it appeared on publication. Key features: Holistic treatment, collecting together a series of important biogeographical papers into a single volume Authored by an expert who has spent nearly three decades actively involved in biogeography Describes and interprets a region of exceptional biodiversity and extreme endemism The only book to provide an integrated treatment of Wallacea, Melanesia, New Zealand, the New Zealand Subantarctic Islands and Antarctica Offers a critique of fashionable neo-dispersalist arguments, showing how these still suffer from the same weaknesses of the original Darwinian formulation. The chapters also include analysis of many major theoretical and philosophical issues of modern biogeographic theory, so that those interested in a more philosophical approach will find the book stimulating and thought-provoking.

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.

Donald R. Prothero's Evolution is an entertaining and rigorous history of the transitional forms and series found in the the fossil record. Its engaging narrative of scientific discovery and well-grounded analysis has led to the book's widespread adoption in courses that teach the nature and value of fossil evidence. Evolution tackles flood geology, rock dating, neo-Darwinism, and macroevolution. It includes extensive coverage of the primordial soup, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, and the transformation from chimpanzee to human. The book details the many "missing links," including some of the most recent discoveries, that flesh out the fossil timeline and the evolutionary process. In this second edition, Prothero describes new transitional fossils from various periods, vividly depicting such bizarre creatures as the Odontochelys, or the "turtle on the half shell," fossil snakes with legs, and the "Frogamander," a new example of amphibian transition. Prothero's discussion of intelligent-design arguments includes more historical examples and careful examination of the "experiments" and observations that are exploited by creationists seeking to undermine sound science education. With new perspectives, Prothero reframes creationism more as a case study in denialism and pseudoscience than as a field with its own intellectual dynamism. The first edition was hailed as the best book on the fossil evidence for evolution, and this second edition will be welcome in the libraries of scholars, teachers, and general readers who stand up for sound science.

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.

Millions of years ago in the Cretaceous period, the mighty Tyrannosaurus rex--with its dagger-like teeth for tearing its prey to ribbons--was undoubtedly the fiercest carnivore to roam the Earth. Yet as "What Bugged the Dinosaurs?" reveals, T. rex was not the only killer. George and Roberta Poinar show how insects--from biting sand flies to disease-causing parasites--dominated life on the planet and played a significant role in the life and death of the dinosaurs.

The Poinars bring the age of the dinosaurs marvelously to life. Analyzing exotic insects fossilized in Cretaceous amber at three major deposits in Lebanon, Burma, and Canada, they reconstruct the complex ecology of a hostile prehistoric world inhabited by voracious swarms of insects. The Poinars draw upon tantalizing new evidence from their amazing discoveries of disease-producing vertebrate pathogens in Cretaceous blood-sucking flies, as well as intestinal worms and protozoa found in fossilized dinosaur excrement, to provide a unique view of how insects infected with malaria, leishmania, and other pathogens, together with intestinal parasites, could have devastated dinosaur populations.

A scientific adventure story from the authors whose research inspired "Jurassic Park," "What Bugged the Dinosaurs?"? offers compelling evidence of how insects directly and indirectly contributed to the dinosaurs' demise.

Land bridges are the causeways of biodiversity. When they form, organisms are introduced into a new patchwork of species and habitats, forever altering the ecosystems into which they flow; and when land bridges disappear or fracture, organisms are separated into reproductively isolated populations that can evolve independently. More than this, land bridges play a role in determining global climates through changes to moisture and heat transport and are also essential factors in the development of biogeographic patterns across geographically remote regions. In this book, paleobotanist Alan Graham traces the formation and disruption of key New World land bridges and describes the biotic, climatic, and biogeographic ramifications of these land masses' changing formations over time. Looking at five land bridges, he explores their present geographic setting and climate, modern vegetation, indigenous peoples (with special attention to their impact on past and present vegetation), and geologic history. From the great Panamanian isthmus to the boreal connections across the North Atlantic and North Pacific Oceans that allowed exchange of organisms between North America, Europe, and Asia, Graham's sweeping, one-hundred-million-year history offers new insight into the forces that shaped the life and land of the New World.

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. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

What do we now know about the origins of plants on land, from an evolutionary and an environmental perspective? The essays in this collection present a synthesis of our present state of knowledge, integrating current information in paleobotany with physical, chemical, and geological data.

From one of the world's leading natural scientists and the acclaimed author of "Trilobite , Life: A Natural History of Four Billion Years of Life on Earth" and "Dry Storeroom No. 1 "comes a fascinating chronicle of life's history told not through the fossil record but through the stories of organisms that have survived, almost unchanged, throughout time. Evolution, it seems, has not completely obliterated its tracks as more advanced organisms have evolved; the history of life on earth is far older--and odder--than many of us realize.
Scattered across the globe, these remarkable plants and animals continue to mark seminal events in geological time. From a moonlit beach in Delaware, where the hardy horseshoe crab shuffles its way to a frenzy of mass mating just as it did 450 million years ago, to the dense rainforests of New Zealand, where the elusive, unprepossessing velvet worm has burrowed deep into rotting timber since before the breakup of the ancient supercontinent, to a stretch of Australian coastline with stromatolite formations that bear witness to the Precambrian dawn, the existence of these survivors offers us a tantalizing glimpse of pivotal points in evolutionary history. These are not "living fossils" but rather a handful of tenacious creatures of days long gone.
Written in buoyant, sparkling prose, "Horseshoe Crabs and Velvet Worms" is a marvelously captivating exploration of the world's old-timers combining the very best of science writing with an explorer's sense of adventure and wonder.

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.

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.

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.

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.

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.
