Paleomagnetic data are useful in many applications in Earth Science from determining paleocurrent directions to analyzing the long-term behavior of the geomagnetic field.

In this book, an attempt has been made to draw together the various principles and practices within paleomagnetism in a consistent and up-to-date manner. It includes many practical examples that illustrate various applications of paleomagnetism. A companion software package implements the theory explained in the text.

Audience: This volume is aimed at professional Earth Scientists using paleomagnetic data for their research. It is also suitable for use as a text book for students in courses with a paleomagnetic content. In addition, this volume will be of value to other professionals with an interest in the analysis of vector and tensor data in general.

Palaeohydrological research is a comparatively recent development. However, research undertaken has already demonstrated a significant multidisciplinary impact and shown how palaeohydrology can provide an important contribution to the study of global change. Although a considerable amount of exciting palaeohydrological research has been applied to particular areas, there has not previously been a systematic approach to research into the palaeohydrology of the Earth's surface. It was for this reason that a Commission was established by INQUA in 1991 on Global Continental Palaeohydrology. This volume provides the background to that exciting international research project and has been written to provide a basis for understanding the current state of research into the palaeohydrology of the land surface of the Earth. It therefore gives a summary of the work achieved to date and of the research investigations currently taking place, together with an indication of the way in which palaeohydrological research relates to other global research programmes.

This new text sets out to establish the key role played by systematics in deciphering patterns of evolution from the fossil record. It begins by considering the nature of the species in the fossil record and then outlines recent advances in the methodology used to establish phylogenetics relationships, stressing why fossil evidence can be crucial. The way species are grouped into higher taxa, and how this affects their utility in evolutionary studies is also discussed. Because the fossil record abounds with sampling and preservational biases, the book emphasizes that observed patterns can rarely be taken at face value. It is argued that evolutionary trees, constructed from combining phylogenetic and biostratigraphic data, provide the best approach for investigating patterns of evolution through geologic time.
The only integrated text covering the study of evolutionary patterns from a phylogenetic stance.

Geared towards a broad variety of students, Dinosaurs: The Textbook, sixth edition, is a concise and lucid presentation of the biological and geological concepts of dinosaur science. It clarifies the evolution, phylogeny, and classification of the various species while modeling the best approach for navigating new and existing research. Revised to reflect recent fossil discoveries and the current consensus on dinosaur science, this text moves through the major taxonomic groups-including theropods, sauropodomorphs, ornithopods, ceratopsians, pachycephalosaurs, stegosaurs, and ankylosaurs-and concludes with updated chapters on the behavior and extinction of the dinosaurs, their biological relationship to birds, and their representation (or misrepresentation) in art, literature, film, and other forms of popular culture. The sixth edition represents a major revision of the leading text for an introductory course on dinosaurs, including comprehensive updates based on the latest scientific discoveries, research, and literature. With an extensive art program revised by leading paleoartists that features cutting-edge illustrations, it is a complete reader-friendly pedagogical package with extensive end-of-chapter summary tools, review questions, a detailed glossary, a dinosaur dictionary, and a comprehensive index. Please visit our supplemental materials page (https://cup.columbia.edu/extras/supplement/dinosaurs-the-textbook-sixth-edition) to find study and teaching aides for both students and teachers using Dinosaurs: The Textbook, sixth edition in class.

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.

The highly fossiliferous upper Darriwilian to lower Sandbian Elnes Formation of Norway presents an interesting insight into the general responses and preferences of Lower Palaeozoic faunas belonging to a stable, mud dominated middle to outer shelf environment in connection with a major transgressive to regressive system tract. The rich trilobite fauna consisting of nearly 100 taxa is closely linked to the changes in the environment, being most abundant in a muddy and siliciclastic dominated environment just above storm wave base. The fauna is highly endemic for the region and the remainder of Baltoscania. This monograph presents a taxonomic description of the total trilobite fauna, including a new genus and seven hitherto unknown species. New and extensive biostratigraphical data is presented on the trilobites together with a study on the biogeographical and ecological aspects of the faunas.

Placing evolutionary events in the context of geological time is a fundamental goal in paleobiology and macroevolution. In this Element we describe the tripartite model used for Bayesian estimation of time calibrated phylogenetic trees. The model can be readily separated into its component models: the substitution model, the clock model and the tree model. We provide an overview of the most widely used models for each component and highlight the advantages of implementing the tripartite model within a Bayesian framework.

The question of the existence of other worlds and other living beings has been present in the human quest for knowledge since as far as Epicurus. For centuries this question belonged to the fields of philosophy and theology. The theoretical problem of the formation of the Solar System, and hence of other planetary systems, was tackled only during the 18th century, while the first observational attempts for a detection started less than one hundred years ago. Direct observation of an extra-solar planetary system is an extraordinarily difficult problem: extra-solar planets are at huge distances, are incredibly faint and are overwhelmed by the bright light of their own stars. With virtually no observational insight to test their models, theoreticians have remained for decades in a difficult position to make substantial progress. Yet, the field of stellar formation has provided since the 1980s both the the oretical and observational evidences for the formation of discs at the stage of star birth and for debris materials orbiting the very young stellar systems. It was tempting to consider that these left-overs might indeed later agglomerate into planetary systems more or less similar to ours. Then came observational evidences for planets outside the Solar System.

This book is volume 33 of the yearbook series 'Palaeoecology of Africa' presenting the outcome of a 'tribute conference' to the internationally recognized South African researcher and palynologist Professor Louis Scott. He has recently retired, but is continuing his active research career. The conference proceedings and articles published here highlight and celebrate Prof. Scott's contribution to palaeoscience and to the natural sciences in general. The conference was organized in July 2014 by the National Museum, Bloemfontein and the University of the Free State, South Africa, and focused on both past and present environments, ecosystems and climates of the arid regions of southern Africa, an area that serves as major focus of Prof. Scott's research. Louis Scott's research interests include stratigraphic palynology, long-term continental environmental change during the Cainozoic, and interpretation of palaeoenvironmental records associated with archaeological sites. His research has contributed insights into the origin of our current environment by identifying long-term patterns of climate change. Results have been applied in numerical models of vegetation change in Africa and globally. The results of these studies are relevant across the fields of botany, geology, climatology, archaeology, anthropology and palaeontology. The chapters revisit and discuss the scientific work of Prof. Scott: among others the reconstructions of vegetation and climatic history in various areas of southern Africa, including the Tswaing Crater with a record of 200 000 years, that give insights into environmental conditions during the Last Glacial Period and the subsequent development of modern conditions. Some observations also provide key baseline information, contributing to understanding past human and environmental contexts and climatic change and the effects of global warming.

This interdisciplinary book interprets early human evolution in the context of the local ecology and adaptation to specific habitats. It systematically assesses the possible role of climate change in driving early human evolution, and evaluates recent fossil finds from an ecological and biogeographic perspective, to provide a novel synthesis of hominid evolution.

Presenting new data on the now classical aspects of Gondwana geology, this work also highlights the increasing international interest as to how the Gondwana supercontinent was assembled. The book is organized according to three themes: assembly, evolution and dispersal, containing 57 papers of specialists in the area.
Assembly: Late Proterozoic-Early Palaeozoic mobile belts of Gondwana, South America, Africa & Australo-Antarctica.
Evolution: Detailed palynological & palaeontological research of Late Palaeozoic- Mesozoic palaeoclimate.
Dispersal: Novel approach to predicting past plate motions followed by series of papers covering the break-up history of Gondwana;

Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

1. 1 Objectives of this Study The vertebrate middle ear has attracted the interest of morphologists for more than a century. Its difficult structure, its complicated evolutionary derivation, and its integration of branchial, cranial, and otic materials into a single func- tional unit have made it a key organ for the understanding of vertebrate structures and their evolutionary history. Gaupp's (1898, 1913) and Reichert's (1837) comparative morphological studies of the vertebrate middle ear repre- sented milestones for anatomy in the general recognition and acceptance of Darwin's theory of evolution. These fundamental studies notwithstanding, today's knowledge of avian middle ear structures is still characterized by descriptive studies focusing on character sampling to elucidate high-level phylogeny. Phylogenetic studies have considered either structural aspects of the bony stapes exclusively (Feduccia 1974, 1975a,b, 1976, 1977, 1978), or focused on the anatomy of the middle ear cavity, neglecting the sound trans- mission apparatus (Saiff 1974, 1976, 1978a,b, 1981, 1982, 1983, 1988). Other studies have investigated late-stage embryos and concentrated on the develop- ment of the skull, considering middle ear structures only as a side aspect. However, there are considerable structural differences between the middle ears of late-stage embryos, hatchlings, and adults of the same species. Although vertebrate morphology requires a meticulous knowledge of comparative middle ear data and calls upon an elaborate system of homologies, it turns out that knowledge of middle ear structural details is widely dispersed among different species and different developmental stages, making a comparison even more difficult.

I am pleased to present this volume of invited reviews and research case studies, produced to mark the retirement of Professor A. G. Smith - one of the leading researchers in Holocene palaeoecology. A. G. Smith took his first degree at the University of Sheffield, graduating in 1951 with a first-class honours degree in Botany. His doctorate was awarded in 1956 for a study in late-Quaternary vege tational history, based in the Sub-Department of Quaternary Research at the University of Cambridge, under the supervision of the late Sir Harry Godwin, FRS. He then researched and taught at Queen's University, Belfast, from 1954, leading the Nuffield Quaternary Research Unit there, becoming Co-Director of the Palaeoecology Laboratory from 1964. He was appointed Professor and Head of the Department of Botany (later, Plant Science) at University College, Cardiff, in 1973, and retired from the School of Pure and Applied Biology at the renamed University of Wales College, Cardiff, in August 1991. Although his principal interests have been concerned with the post-glacial environmental history of the British Isles, Professor Smith has significantly in fluenced many researchers elsewhere in their interpretation of biological and other evidence for human modification of the natural environment.

Recent developments in Pleistocene research have prompted the authors to produce this up-to-date, concise account of environmental changes during the past two million years. Well-illustrated and referenced, it possesses a unique position in the literature on Pleistocene events in the British Isles.

The geologie term "'Tethys" introduced by Eduard Suess (1893) into Reience waR originally a paleogeographic one. Since its original des- eription it has been used in various ways. One of them is Tethys as a paleo-biogeographie eoneept. This eoneept was adopted for IGCP Project 262, Tethyan Cretaeeous Correlation. It was proposed by G. CSASZAR and Heim; A. KOLLMANN and has been approved by the IGCP Board in February 1987. The projeet haR its aimH primarily in the improvement of the stra- tigraphie cOl'relation between the heterogenous faeies of the Tethyan realm.

This book examines case studies of North American Quaternary mammalian evolution within the larger domain of modern evolutionary theory. It presents previously unpublished studies of a variety of taxa (xenarthrans, rodents, carnivores, ungulates) examined over several temporal scales, from a few thousand years during the Holocene to millions of years of late Pliocene and Pleistocene time. Different organizational levels are represented, from mosaic population variation, to a synopsis of Quaternary evolution of an entire order (Rodentia). In addition to specific case histories, the book includes purely theoretical and methodological contributions, for example, on the statistical recognition of stasis in the fossil record, new ways to calculate evolutionary rates, and the use of digital image analysis in the study of dental ontogeny. Perhaps the most important aspect of the studies reported in this book is that they span the time between the "ecological moment" and "deep time." Modern taxa can be traced back into the fossil record, and variation among extant taxa can be used as a control against which variation in the extinct ones can be understood.

Amber is a semi-precious gem that is formed over eons by natural forces out of the resin of trees. Human fascination with amber dates back to prehistoric times, when it was probably considered to have magical powers and was used for adornment and trade. Amber amulets and beads dating from 35,000 to 1,800 B.C. have been found, and where they have been found (for example in graves hundreds of miles from their chemically determined origins) has often helped to establish ancient trade routes. The preservative qualities of plant resins were well known by the ancients. The Egyptians used resins to embalm their dead, and the Greeks used them to preserve their wine. Amber often preserved fossils, frequently in a pristine state, of all kinds of animal and plant organisms that made contact with the sticky substance and became trapped in it. These fossils include such fragile organisms as nematodes and mushrooms that ordinarily are not preserved under normal processes of fossilization, as well as larger organisms like scorpions and lizards, and the fossils are preserved in their full three-dimensional form, complete with minute details of scales, mouth parts, antennae, and hairs. It has even been suggested that viable DNA may persist in some amber-trapped organisms. This book is a compendium of all that we know about life found in amber. It surveys all life forms, from microbes to vertebrates and plants, that have been reported from amber deposits throughout the world, beginning with the earliest pieces dating from some 300 million years ago. It also describes the formation of amber and the location, geological history, and early exploration of the major world amber deposits, including those stillbeing worked today. The book also provides practical information on how to determine fake amber containing present-day forms of life. It can serve as a beginning for tracing the geological history of a particular group of animals or plants or even reconstructing ancient paleoenvironments, and because amber fossils are preserved so completely, in a transparent medium, they can be intimately compared with related living species. Finally, the book discusses what amber fossils can tell us about evolution and speciation, cellular preservation, and paleosymbiosis. The book is illustrated with 37 color photographs, 154 black-and-white photographs and drawings, and 8 maps.

The previously unpublished correspondence of T.H.Huxley with Rev. George Gordon is an important new addition to the literature on Huxley and Victorian science. The correspondence is self-contained and wholely scientific, concerning the unexpected discovery of reptilian fossils and footprints near Elgin, and relates to a most important aspect of Huxley's career: defining the relationship between geology and palaentology. The letters are complemented by an incisive analysis of Huxley's work as a palaentologist and the development of his views on evolution.

Pollen and spores are ubiquitous, and preserve exceptionally well. This, and their enormous structural diversity, offers exceptional opportunities for integrating findings from studies of both recent and fossil material, and for developing new insights into the pathways and processes of diversification. This volume brings together both international authorities and younger researchers who have developed novel approaches from such diverse fields as paleobotany, ontogeny, molecular biology, and systematics. Three main issues are discussed: the evidence provided by the fossil record, the contribution of ontogenetic data, and the methods of systematic analysis. Of special interest are the sections detailing the most recent findings regarding fossil angiosperms and ontogeny in primitive angiosperms. The information provided will be of great interest and relevance to such disparate disciplines as vegetational history, geology, plant taxonomy and plant evolution.

This volume is dedicated to the interdisciplinary study of dynamic biological changes through the Phanerozoic which are associated with mass extinction events and similar biotic crises, and their causal mechanisms. In particular, it documents in detail the complex nature of terrestrial and extraterrestrial feedback loops that are associated with many mass extinction intervals. Authors have been asked to represent most of the known mass extinction events through time, and to comment on the complex earthbound or extraterrestrial causes (or both) for global biotic crises. The reader is offered new perspectives of extinction boundaries, a more innovative and diverse approach to causal mechanisms and mass extinction theory, blended views of paleobiologists, oceanographers, geochemists, volcanologists, and sedimentologists by an international cast of authors. No other book on extinction presents such a broad spectrum of data and theories on the subject of mass extinction.

Dinosaur bones had been found centuries before scientists understood what they were and what creatures they came from; ancient Chinese writings spoke of 'dragon' bones, and large fossils discovered in the UK were thought to belong to human giants. It was only with the exploration and meticulous research of generations of intrepid palaeontologists that the truth about dinosaurs was discovered.

The Dinosaur Hunters tells the story of these discoverers of prehistoric life, and the revelations found through their research. Illustrated with 30 rare documents, photographs and hand-drawn maps, it explores the unearthing of Iguanodon teeth, the discovery of the first flying dinosaur, the infamous Bone Wars and consultant editor Dr Mark Norell's radical study of feathered dinosaurs. This is a tale of daring exploits, luck, science and wanderlust, and of the thrilling lives and work of heroic scientists and adventurers.

Most people are familiar with the dodo and the dinosaur, but extinction has occurred throughout the history of life, with the result that nearly all the species that have ever existed are now extinct. Today, species are disappearing at an ever increasing rate, whilst past losses have occurred during several great crises. Issues such as habitat destruction, conservation, climate change, and, during major crises, volacanism and meteorite impact, can all contribute towards the demise of a group. In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarising what we know about all of the major and minor exctinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions 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.
