Several years ago, we realized that the most prominent ideas that had been ex pressed about the origin and early evolution of the Metazoa seemed to have been developed chiefly by zoologists using evidence from modern species without reference to the fossil record. Paleontologists had, in fact, put forth their own ideas but the zoological and the paleontological evidence were about the problem, seldom considered together, especially by zoologists. We believed that the paleon tological documentation of the first Metazoa was too scattered, too obscure to Western readers, and much of it too recent to have been readily available to our colleagues in zoology. Whether or not that was entirely true, we thought that a single volume reviewing the fossil record of the earliest Metazoa would be useful to many in both paleontology and zoology, especially since so much new informa tion has been developed in the last few years. Some of this information has been summarized in general articles recently, but an overview of most of the field does not exist. We therefore organized this book in five parts so that the evidence could be placed in perspective and summarized and inferences made from it. Part I intro duces the previous hypotheses that have been proposed for the origin and early radiation of Metazoa. Part II consists of two summary chapters that set the sedi mentological, geochemical, and biological background to the known radiations of Metazoa."

The ideal textbook for non-science majors, this lively and engaging introduction encourages students to ask questions, assess data critically and think like a scientist. Building on the success of the previous editions, Dinosaurs has been reorganised and extensively rewritten in response to instructor and student feedback. It continues to make science accessible and relevant through its clear explanations and extensive illustrations. Updated to reflect recent fossil discoveries and to include new taxa, the text guides students through the dinosaur groups, emphasising scientific concepts rather than presenting endless facts. It is grounded in the common language of modern evolutionary biology - phylogenetic systematics - so that students examine dinosaurs as professional paleontologists do. The key emerging theme of feathered dinosaurs, and the many implications of feathers, have been integrated throughout the book, highlighted by the inclusion of stunning new photographs in this beautifully illustrated text, now in full colour throughout.

Seven original case-studies are presented in this volume, each describing the application of micropaleontology and palynology in applied geology: (1) a study of the modern distribution of coccolith sedimentation in the North Sea and its potential for future application in basin analysis; (2) ostracods are shown to be good paleoenvironmental indicators in the early Cretaceous and Tertiary; (3) a biogenic gas seep in the North Sea is shown to be marked by diagnostic benthonic foraminifera; (4) in the North Sea hydrocarbon exploration, integrated studies of micropaleontology have provided invaluable data; (5) palynofacies analysis are shown to be vital in determining depositional events and hydrocarbon source rock potential; (6) the application of paleontology and sedimentology to sequence stratigraphy is demonstrated in the early Cretaceous; and (7) the application of micropaleontology is shown to be an essential tool in both engineering and economic geology. Most chapters have been prepared by earth scientists from industry. The study of microfossils presented in this book provides invaluable data for stratigraphers, petroleum geologists and for engineers and economic geologists working in hydrocarbon exploration and basin analysis.

Echinoderms are an ancient and diverse group of marine animals with a rich fossil record. They occur abundantly in all modern oceans and at all depths, where they contribute importantly to patterns in biodiversity and to the structure and functioning of marine systems. It is therefore vital to understand how they will respond to a rapidly changing ocean climate and other anthropogenic stressors, informed by both the dynamics of the fossil record and responses of extant species. The theme of the 13th International Echinoderm Conference (Hobart, Tasmania, 5-9 January 2009) was the response of echinoderms to global change. Echinoderms in a Changing World contains a selection of plenary and contributed papers, and a comprehensive presentation of abstracts of all oral papers and posters. The collection will be useful to all students of echinoderm biology, ecology and palaeontology, from undergraduate level to professional researchers.

In 2002 the multidisciplinary research project "Nasca: development and adaptation of archaeometric techniques for the investigation of cultural history" (Nasca: Entwicklung und Adaption archa..ometrischer Techniken zur Erforschung der Kulturgeschichte) started, funded by the German Federal Ministry of Education andResearch(Bundesministerium fu..r Bildung und Forschung, BMBF ) in its priority program "New scientific methods and technologies for the humanities" (Neue Naturwissenschaftliche Methoden und Technologien fu..r die Geisteswissenschaften, NTG). This new project continued and in a certain way fulfilled a lasting goal of the ministry to integrate different branches of scientific activities and to foster the transfer of expertise gained in natural sciences to the humanities and vice versa. Archaeometry, by definition the application of scientific methods in archaeological investigation, has been a major focus of the priority program since its beginnings in 1989. After funding numerous fruitful research projects that developed new archaeometric techniques mostly in bilateral cooperation, an even greater outcome was expected from a more multifaceted approach with the participation of various scientific disciplines around a well-defined, archaeological research topic. Furthermore, it was intended to establish a project outside the traditional research areas in central Europe or the Mediterranean. It was the great merit of the person formerly in charge of the BMBF priority program, Dr. Edgar Pusch, to develop these far-reaching perspectives and we are extremely grateful that after a rigorous screening our project among other interesting ones was selected for funding.

Humans are the only mammals to walk on two, rather than four, legs. From an evolutionary perspective, this is an illogical development, as it slows us down. But here we are, suggesting there must have been something tremendous to gain from bipedalism. First Steps takes our ordinary, everyday walking experience and reveals how unusual and extraordinary it truly is. The seven-million-year-long journey through the origins of upright walking shows how it was in fact a gateway to many of the other attributes that make us human-from our technological skills and sociality to our thirst for exploration. DeSilva uses early human evolution to explain the instinct that propels a crawling infant to toddle onto two feet, differences between how men and women tend to walk, physical costs of upright walking, including hernias, varicose veins and backache, and the challenges of childbirth imposed by a bipedal pelvis. And he theorises that upright walking may have laid the foundation for the traits of compassion, empathy and altruism that characterise our species today and helped us become the dominant species on this planet.

The twelve contributions in this volume represent the results of a ten year interdisciplinary workshop on "desert margins" - concerned with the geomorphological, geochemica, mineralogical, sedimentological, soil scientific characterisation of (semi-) deserts in Spain, Africa, Arabia and China. Desert sediments and soils as well as processes and characteristics of their formation are regarded from different geoscientific perspectives. The subjects of research include the development of desert soils and landscapes, the formation of (alluvial) loess, swamp ores, fulgurites and floodout sediments and focus on the reconstruction of palaeoecological events and changes. A critical study of dating methods rounds off the book.

From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The overviews of established and emerging techniques for studying modern and ancient microorganisms on Earth and beyond, will be valuable guides to evaluating biosignatures which could be found in the extraterrestrial surface or subsurface within the Solar System and beyond. This volume also provides discussion on the controversial reports of "nanobacteria" in the Martian meteorite ALH84001. It is a unique volume among Astrobiology monographs in focusing on fossil evidence from the geological record and will be valuable to students and researchers alike.

INTERNATIONAL SOCIETY FOR EVOLUTIONARY PROTISTOLOGY (ISEP) 5th International Meeting 1983 Banyuls-sur-Mer, France, June 4-6, 1 For the first time since its inception, at Boston University in June 1975 , the Society for Evolutionary Protistology met in Europe. Under the direction of Marie-Odile Soyer- Gobillard and hosting some 70 people representing a dozen nations (Belgium, Canada, Denmark, England, France, W. Germany, The Netherlands, Poland, Scotland, Spain, Switzerland, U. S. A. ) the meeting was held at Banyuls-sur-Mer in Catalunya. The 1983 ISEP met at the famed Laboratoire Arago on the Mediterranean Sea, most partici- pants were housed in the Laboratory's newly refurbished Grand Hotel. The previous meetings had emphasized single themes, e. g. , (First) Boston, 1975 Evolution of Mitosis in Eukaryotic Microorganisms: (Second) Downsview Ontario, 1977 Criteria for Phylogeny in Protists. In spite of the fact that the third meeting, planned for Leeds, England in June of 1979, was never held some of the papers scheduled to be presented there were published in BioSystems, Volume 12, Numbers 1 and 2. The fourth meeting at Port Deposit, Maryland, 1981 called Conference on Cellular Evolution focused on the Evolution of Micro tubules, Mitosis, Microfilaments and other Fibrillar Systems. The proceedings of this meeting were published in BioSystems, Volume 14, Numbers 3 and 4.

Paleontologists and geologists struggle with research questions often complicated by the loss or even absence of key paleobiological and paleoenvironmental information. Insight into this missing data can be gained through direct exploration of analogous living organisms and modern environments. Creative, experimental and interdisciplinary treatments of such ancient-Earth analogs form the basis of Lessons from the Living. This volume unites a diverse range of expert paleontologists, neontologists and geologists presenting case studies that cover a spectrum of topics, including functional morphology, taphonomy, environments and organism-substrate interactions.

Most major recent advances in understanding the history of life on Earth have been through the study of exceptionally well preserved biotas (Fossil-Lagerstatten). These are windows on the history of life on Earth and can provide a fairly complete picture of the evolution of ecosystems through time. This book follows the success of Evolution of Fossil Ecosystems by the same authors which covered Fossil-Lagerstatten around the world. The success of the first book prompted this new book which draws on four localities from the original book and adds another ten, all located in North America. Following an introduction to Fossil-Lagerstatten, each chapter deals with a single fossil locality. Each chapter contains a brief introduction placing the Lagerstatte in an evolutionary context; there then follows a history of study of the locality; the background sedimentology, stratigraphy and palaeoenvironment; a description of the biota; discussion of the palaeoecology, and a comparison with other Lagerstatten of a similar age and/or environment. At the end of the book is an Appendix listing museums in which to see exhibitions of fossils from each locality and suggestions for visiting the sites.

In the present book the Paleogene fossil record of birds is detailed for the first time on a worldwide scale. I have developed the idea for such a project for several years, and think that it is an appropriate moment to present a summary of our c- rent knowledge of the early evolution of modern birds. Meanwhile not only is there a confusing diversity of fossil taxa, but also significant progress has been made concerning an understanding of the higher-level phylogeny of extant birds. Hypotheses which were not considered even a decade ago are now well supported by independent analyses of different data. In several cases these group together morphologically very different avian groups and allow a better understanding of the mosaic character distribution found in Paleogene fossil birds. The book aims at bringing some of this information together, and many of the following data are based on first-hand examination of fossil specimens.

If theoretical physicists can seriously entertain canonical "standard models" even for the big-bang generation of the entire universe, why cannot life scientists reach a consensus on how life has emerged and settled on this planet? Scientists are hindered by conceptual gaps between bottom-up inferences (from early Earth geological conditions) and top-down extrapolations (from modern life forms to common ancestral states). This book challenges several widely held assumptions and argues for alternative approaches instead. Primal syntheses (literally or figuratively speaking) are called for in at least five major areas. (1) The first RNA-like molecules may have been selected by solar light as being exceptionally photostable. (2) Photosynthetically active minerals and reduced phosphorus compounds could have efficiently coupled the persistent natural energy flows to the primordial metabolism. (3) Stochastic, uncoded peptides may have kick-started an ever-tightening co-evolution of proteins and nucleic acids. (4) The living fossils from the primeval RNA World thrive within modern cells. (5) From the inherently complex protocellular associations preceding the consolidation of integral genomes, eukaryotic cell organization may have evolved more naturally than simple prokaryote-like life forms. - If this book can motivate dedicated researchers to further explore the alternative mechanisms presented, it will have served its purpose well.

Deep in the wilderness of northern Maine in the mid-1950s, a Harvard PhD student is wading down a mountain stream into a remote valley. He is taking his first steps to map the geology of 300 square miles of Baxter State Park. He soon discovers a series of unusually shaped rock outcrops-part of an unknown geologic formation, hundreds of millions of years old, still mystifying today because of its relative lack of change despite nearby volcanic activity and massive land movement. Wading on, he has another surprise. In a thin layer of black shale beside the stream, he finds a small fossil of a plant. Little does he know, but his discovery of Perticaquadrifaria will help scientists unlock the details of a major event in the history of our planet-the transition of plants to land, an occurrence that continues to have a critical influence on the Earth's life-supporting processes, including climate. The 400-million-year-old, Devonian Era Pertica fossils have been found nowhere else on Earth but that enigmatic rock formation deep in the Maine woods. Pertica was one of the very first land plants and is thought to have been the tallest of the time. Today, the site of the fossil's discovery lies in the shadow of an Eastern White Pine, which now takes the ancient plant's place as the tallest plant on the land in the eastern United States. This fascinating story explores the work of geologists and paleobotanists as they attempt to demystify the land and reveal the ancient life forms that settled on it. It explores the hypothesis that these two tall plants (Pertica and White Pine) are related and asks: What can these two plants, one ancient, and one modern, tell us about the past and perhaps hint at the future?

Are we now entering a mass extinction event? What can mass extinctions in Earth's history tell us about the Anthropocene? What do mass extinction events look like and how does life on Earth recover from them? The fossil record reveals periods when biodiversity exploded, and short intervals when much of life was wiped out in mass extinction events. In comparison with these ancient events, today's biotic crisis hasn't (yet) reached the level of extinction to be called a mass extinction. But we are certainly in crisis, and current parallels with ancient mass extinction events are profound and deeply worrying. Humanity's actions are applying the same sorts of pressures - on similar scales - that in the past pushed the Earth system out of equilibrium and triggered mass extinction events. Analysis of the fossil record suggests that we still have some time to avert this disaster: but we must act now.

This book presents a detailed examination of the current state of knowledge in the field of paleoneurology in the main amniote groups (reptiles, birds and mammals), and advances resulting from new non-invasive technologies. The study of fossil endocasts is an area of considerable current interest, and has long been central to our understanding of the evolution of the brain, development of senses and behavioral adaptations in diverse vertebrate groups and across vertebrates as a whole. Recent advances in non-invasive imaging have significantly increased the number of fossil taxa for which brain morphology is known, and it may now be possible to quantitatively analyze the relative size of brain regions. Providing a general overview of current perspectives and problems in evolutionary neuroanatomy, this book is intended for a wide range of readers, including undergraduate and graduate students, teachers, and anyone with a special interest in paleoneurology. It is also useful as supplementary reading for courses in digital anatomy, vertebrate comparative anatomy, computed morphometrics, paleontology, neurology and radiology as well as evolution programs

Increasing rate of species extinction in the present day will lead to a huge biodiversity crisis; eventually, this will lead to the paucity of non-renewable resources of energy making our Earth unsustainable in future. To save our mother planet from this crisis, studies need to be performed to discover abundant new fossil sites on Earth for continued access to oil-rich locations. Most importantly, a holistic approach is necessary in solving the present problem of biodiversity loss. This book presents newly developed quantitative models in understanding the biodiversity, evolution and ecology of extinct organisms. This will assist future earth scientists in understanding the natural and anthropogenic causes behind biodiversity crisis and ecosystem collapse. In addition, this study would be of great interest to exploration geologists and geophysicists in potentially unraveling natural resources from our sustainable Earth.

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in virtually all habitats. Some are commercially important, a few are pests and some carry diseases, while many non-marine molluscs are threatened by human impacts which have resulted in more extinctions than all tetrapod vertebrates combined. This book and its companion volume provide the first comprehensive account of the Mollusca in decades. Illustrated with hundreds of colour figures, it reviews molluscan biology, genomics, anatomy, physiology, fossil history, phylogeny and classification. This volume includes general chapters drawn from extensive and diverse literature on the anatomy and physiology of their structure, movement, reproduction, feeding, digestion, excretion, respiration, nervous system and sense organs. Other chapters review the natural history (including ecology) of molluscs, their interactions with humans, and assess research on the group. Key features of both volumes: up to date treatment with an extensive bibliography; thoroughly examines the current understanding of molluscan anatomy, physiology and development; reviews fossil history and phylogenetics; overviews ecology and economic values; and summarises research activity and suggests future directions for investigation. Winston F Ponder was a Principal Research Scientist at The Australian Museum in Sydney where he is currently a Research Fellow. He has published extensively over the last 55 years on the systematics, evolution, biology and conservation of marine and freshwater molluscs, as well as supervised post graduate students and run university courses. David R. Lindberg is former Chair of the Department of Integrative Biology, Director of the Museum of Paleontology, and Chair of the Berkeley Natural History Museums, all at the University of California. He has conducted research on the evolutionary history of marine organisms and their habitats on the rocky shores of the Pacific Rim for more than 40 years. The numerous elegant and interpretive illustrations were produced by Juliet Ponder.

This volume reviews the meaning of taxonomic statements and considers our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behaviour changes and selection pressures in evolutionary sequences. First published in 1964.

This book is the first of its kind on environmental change research devoted to monsoon-arid environment evolution history and its mechanism involved. Capturing the most prominent features of Asian climate and environmental changes, it gives a comprehensive review of the Asian Monsoon records providing evidence for spatial and temporal climatic and environmental changes across the Asian continent since the Late Cenozoic. The dynamics underlying these changes are explored based on various bio-geological records and in particular based on the evidence of loess, speleothems as well as on mammal fossils. The Asian monsoon-arid climate system which quantifies the controlling mechanisms of climate change and the way it operates in different time scales is described. Attempts to differentiate between natural change and human-induced effects, which will help guide policies and countermeasures designed to support sustainable development on the Chinese Loess Plateau and the arid west.

This book presents the multidisciplinary results of an extensive underwater excavation in north Florida which yields the most complete results of interactions between early Paleoindians and late Pleistocene megafauna, especially Mammut americanum (American Mastodon), in a rich environmental context in eastern North America. It provides fundamental insights into two urgent issues: "The Peopling of the Americas"; and "The Extinction of the Megafauna."

The authors describe and illustrate their unique methods of precise underwater excavations. They show how these techniques allowed them to collect a diversity of zoological, botanical and cultural material with outstanding organic preservation.

This wealth of prehistoric evidence was recovered during twenty years of delving into an ancient sinkhole in the bottom of the Aucilla River. The nearly continuous sequence of fine-grained sediments, with an abundance of carbon dates, place the climatic and environmental history of this area in a global context of late glacial climatic cycles. The deepest strata produce clear evidence that the first Floridians lived and hunted here some 14,000 years ago, indicating that this southeastern culture preceded classic Clovis culture in western North America.

Clever studies of stable isotopes tell that the Mastodons migrated north out of Florida into glacial terrain during the winter and spring and their digesta, which also contain steroids and epithelial cells, display a rich summer diet.

The last section of the book provides a wealth of new evidence from the early Holocene about the flora and climate and how early Archaic people subsisted after the megafauna became extinct.
