This overview of dinosaur discoveries in Mexico synthesizes current information about the geography and environment of the region during the Mesozoic when it was the western margin of the ancient continent of Pangea. The book summarizes research on various groups, including turtles, lepidosauromorphs, plesiosaurs, crocodyliforms, pterosaurs, and last but not least, dinosaurs. In addition, chapters focus on trackways and other trace fossils and on K/P boundary (the Chicxulub crater, beneath the Gulf of Mexico, has been hypothesized as the site of the boloid impact that killed off the dinosaurs). Dinosaurs and Other Reptiles from the Mesozoic of Mexico is an up-to-date, informative volume on an area that has not been comprehensively described until now.

More than 10,000 years ago spectacularly large mammals roamed the pampas and jungles of South America. This book tells the story of these great beasts during and just after the Pleistocene, the geological epoch marked by the great ice ages. Megafauna describes the history and way of life of these animals, their comings and goings, and what befell them at the beginning of the modern era and the arrival of humans. It places these giants within the context of the other mammals then alive, describing their paleobiology-how they walked; how much they weighed; their diets, behavior, biomechanics; and the interactions among them and with their environment. It also tells the stories of the scientists who contributed to our discovery and knowledge of these transcendent creatures and the environment they inhabited. The episode known as the Great American Biotic Interchange, perhaps the most important of all natural history "experiments," is also an important theme of the book, tracing the biotic events of both North and South America that led to the fauna and the ecosystems discussed in this book. -- Indiana University Press

'Vivid, thrilling, a delight ... Tim Flannery is a palaeontologist and ecologist of global standing, and this is a compelling and authoritative narrative of the evolution of Europe's flora and fauna, from the formation of the continent to its near future ... an exciting book, full of wonder' James McConnachie, Sunday Times A place of exceptional diversity, rapid change, and high energy, Europe has literally been at the crossroads of the world ever since the interaction of Asia, North America and Africa formed the tropical island archipelago that would become the continent of today. In this unprecedented evolutionary history, Tim Flannery shows how for the past 100 million years Europe has absorbed wave after wave of immigrant species; taking them in, transforming them, and sometimes hybridising them. Flannery reveals how, in addition to playing a vital role in the evolution of our own species, Europe was once the site of the formation of the first coral reefs, the home of some of the world's largest elephants, and now has more wolves than North America. This groundbreaking book charts the history of the land itself and the forces shaping life on it - including modern humans - to create a portrait of a continent that continues to exert a huge influence on the world today.

"Bones of Contention" is a behind-the-scenes look at the search for human origins. Analyzing how the biases and preconceptions of paleoanthropologists shaped their work, Roger Lewin's detective stories about the discovery of Neanderthal Man, the Taung Child, Lucy, and other major fossils provide insight into this most subjective of scientific endeavors. The new afterword looks at ways in which paleoanthropology, while becoming more scientific
in many ways, remains contentious.
"[An] un-put-downable book."--John Gribbon, "Times Educational Supplement"
"Not just another 'stones and bones' account of human evolution. It is Lewin's thesis, amply demonstrated, that paleoanthropology is the most subjective of sciences because it engages the emotions of virtually everyone; and since the evidence is scrappy, interpretation is everything. . . . A splendid, stirring, and eye-opening account, to be devoured."--"Kirkus Reviews," starred review
"[Lewin shows] 'how very unscientific the process of scientific inquiry can be.'. . . "Bones of Contention" is . . . serious intellectual history."--Edward Dolnick, "Wall Street Journal"
"[Lewin] documents his thesis in persuasive detail. . . . The reader is carried along by the power of Mr. Lewin's reporting."--Robert Wright, "New York Times Book Review"

The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.

This volume presents state-of-the-art papers on important topics and methods in the analysis of vertebrate microfossil assemblages. The minute remains of animals and plants have proven very useful to paleontologists as tools for dating large fossils, describing the environments which existed at the time the fossils were deposited, and identifying and mapping the extent of local floras and faunas, among other things. Due to the large sample sizes that can be obtained, the chance to recover rare taxa is much higher than it is during a search for skeletal remains. Analysis of the data produced from microvertebrate localities can address a wide range of questions as these papers clearly demonstrate.

The aim of the atlas is to provide images of taphonomic modifications, making it as comprehensive as possible with evidence presently available. This volume is intended both as a field guide for identifying taphonomic modifications in the field, and for use in the laboratory when collections of fossils are being analyzed. Images in the book are a combination of scanning electron micrographs, regular photographs, cross-sections of bones and line drawings and graphs. By providing good quality illustrations of taphonomic modifications, with links between similar types of modification, the atlas provides a reference source for identifying the agents responsible for the modifications, the processes by which they were formed, and the potential bias introduced by the processes. The authors also aim to emphasize on the directions they consider taphonomic studies should be headed. Firstly, we should seek to quantify the degree of bias introduced into a fossil fauna and to take account of this bias before interpreting the palaeoecology of the fossil site. Secondly, we should recognize that taphonomic modifications increase the information encoded in fossils by identifying perimortem and postmortem contexts. This provides a more dynamic and realistic view of the past.

This study is organized around three themes: the origin and early diversification of life during the Archean Eon; the maturation of life and the Earth during the long Proterozoic Eon; and the explosive diversification of multicellular life that marks the dawn of the Phanerozoic Eon. The contributors discuss the coherence of history, the combinatorial generation of taxonomic diversity, early Metazoan evolution, and the Cambrian explosion.

During an expedition in Sonora, Mexico, paleontologist Mark A. S. McMenamin unearthed fossils of creatures dated at approximately 600 million years old -- making them the oldest large body fossils ever discovered. These circular fossils, known as Ediacarans, seemed to defy explanation. Representatives of marine life forms that existed in Precambrian times, as much as fifty million years before life on earth began to diversify rapidly, the specimens bore a superficial resemblance to jellyfish.

A typical Ediacaran had a quilted body, three curving arms at the center, and a fringe of fine radial lines. McMenamin's curiosity was fueled by the puzzle of whether the Ediacarans were animals or some other type of organism. How could such complex forms of life appear so suddenly, without extensive records of prior evolution? Yet, this seems to be exactly what the Ediacarans had done.

"The Garden of Ediacara" presents a mesmerizing documentary of a major scientific discovery, detailing McMenamin's trip to Namibia, where, with a party that included the renowned paleontologist Adolf Seilacher, the author investigates a spectacular cast made from a colony of fossils in the Nama desert. He chronicles the long, often futile search made by earlier scientists for Ediacara, which began more than a century ago in Europe, North America, and Africa, and the various types of Ediacaran fossils that have been uncovered in the years since.

McMenamin concludes that Ediacarans were not animals because they never passed through the ball-shaped embryonic stage peculiar to known animal life forms. But, remarkably, Ediacarans seem to have developed a central nervous system and a brain independent from animal evolution. This startling conclusion has profound implications for our understanding of evolutionary biology, for it indicates that the path toward intelligent life was embarked upon more than once on this planet.

Featuring numerous illustrations, this book explores the many lessons to be learned from Pleistocene megafauna, including the role of humans in their extinction, their disappearance at the start of the Sixth Extinction, and what they might teach us about contemporary conservation crises. Long after the extinction of dinosaurs, when humans were still in the Stone Age, woolly rhinos, mammoths, mastodons, sabertooth cats, giant ground sloths, and many other spectacular large animals that are no longer with us roamed the Earth. These animals are regarded as "Pleistocene megafauna," named for the geological era in which they lived-also known as the Ice Age. In Vanished Giants: The Lost World of the Ice Age, paleontologist Anthony J. Stuart explores the lives and environments of these animals, moving between six continents and several key islands. Stuart examines the animals themselves via what we've learned from fossil remains, and he describes the landscapes, climates, vegetation, ecological interactions, and other aspects of the animals' existence. Illustrated throughout, Vanished Giants also offers a picture of the world as it was tens of thousands of years ago when these giants still existed. Unlike the case of the dinosaurs, there was no asteroid strike to blame for the end of their world. Instead, it appears that the giants of the Ice Age were driven to extinction by climate change, human activities-especially hunting-or both. Drawing on the latest evidence provided by radiocarbon dating, Stuart discusses these possibilities. The extinction of Ice Age megafauna can be seen as the beginning of the so-called Sixth Extinction, which is happening right now. This has important implications for understanding the likely fate of present-day animals in the face of contemporary climate change and vastly increasing human populations.

William Diller Matthew (1871-1930), who could be called the Father of Mammalian Paleontology, occupies a major position in the history of North American paleontology. In his biography of this paleontologist's paleontologist, Edwin Colbert paints a compelling portrait of the scientist's life and work. Using personal letters, archives, and accounts from those who knew Will Matthew, Colbert presents a delightful and informative account of Matthew's experiences around the turn of the century, complete with photographs of his excavations, world travels, time in New York, family, and environs. Matthew's unique contribution to science rested on his dual perspective as both geologist and paleontologist. He diligently collected and catalogued fossils while at the same time noting stratigraphic details that gave significant time-related information on these fossils. Matthew wrote widely on paleontology at the turn of the century, but most well known is his extensive essay "Climate and Evolution", written in 1915, which attracted almost immediate attention from the paleontological-zoological community. Characteristic of his no-nonsense approach to his work, this essay remains vital and inspirational to paleontological researchers today. Will Matthew was also keen on reaching the public at large and published profusely in the American Museum Journal (which after 1918 became Natural History magazine), where he described his fossil finds, new exhibits, and other interesting research. He also published several American Museum guide leaflets on specific subjects, such as the horse. His informative description "'The Horse', wrote a small boy in his essay, 'is the square animal with a leg at eachcorner, '" - a definition that obviously charmed Matthew. Peppered with such anecdotes, the engaging and highly readable William Diller Matthew, Paleontologist: The Splendid Drama Observed vividly depicts a man respected and revered by many generations of scientists.

Here is the fifth supplement to Dinosaurs: The Encyclopedia, a 1998 American Library Association Outstanding Reference Book. Since the publication of the acclaimed first volume, a virtual explosion in the number of exciting discoveries in dinosaur paleontology has made supplemental volumes necessary and indispensable. Among the many dramatic events discussed in the fifth supplement are the discovery of what may be the largest Jurassic theropod specimen yet collected; the uncovering of evidence of a dinosaur possessing opposable fingers; and Robert M. Sullivan's reassessment of Pachycepholasauria. Like the previous supplements, this volume includes lengthy sections on dinosaurian schematics and genera and updates the encyclopedia's list of excluded genera. Supplemental volumes do not repeat information from earlier volumes, but build upon them: view all volumes on the series page.

Documentation of a study of the Cretaceous Echinoids Cretaceous Echinoids from Northeastern Brazil is Number 31 within the Fossils and Strata series of monographs and memoirs in palaeontology and biostratigraphy. The international Fossils and Strata series features systematic and regional monographs with taxonomic descriptions. The series is owned by and published on behalf of The Lethaia Foundation with collaboration among the Scandinavian countries.

How can the tracks of dinosaurs best be interpreted and used to reconstruct them? In many Mesozoic sedimentary rock formations, fossilized footprints of bipedal, three-toed (tridactyl) dinosaurs are preserved in huge numbers, often with few or no skeletons. Such tracks sometimes provide the only clues to the former presence of dinosaurs, but their interpretation can be challenging: How different in size and shape can footprints be and yet have been made by the same kind of dinosaur? How similar can they be and yet have been made by different kinds of dinosaurs? To what extent can tridactyl dinosaur footprints serve as proxies for the biodiversity of their makers? Profusely illustrated and meticulously researched, Noah's Ravens quantitatively explores a variety of approaches to interpreting the tracks, carefully examining within-species and across-species variability in foot and footprint shape in nonavian dinosaurs and their close living relatives. The results help decipher one of the world's most important assemblages of fossil dinosaur tracks, found in sedimentary rocks deposited in ancient rift valleys of eastern North America. Those often beautifully preserved tracks were among the first studied by paleontologists, and they were initially interpreted as having been made by big birds-one of which was jokingly identified as Noah's legendary raven.

In some cases, scientific research into the space-time continuum may have unexpected] consequences... as occurs in Isaac Asimov s short story "'A Statue for Daddy.' In this tale... two scientists... recover 14 dinosaur eggs. The eggs are carefully incubated, and they hatch bipedal dinosaurs about the same size as a medium-sized dog. One of them is accidentally electrocuted, and the scientists discover that their meat is truly exquisite. They become fabulously rich rearing and marketing dinosaur meat under the name of 'dinochicken.'"

Ever since the discovery of the first fossil remains in the 19th century, dinosaurs have captured the imaginations of scientists and inspired writers, artists, and filmmakers. Dinosaurs, and legends about them are firmly entrenched in popular culture, where scientific information and our interest in the life of the past most often meet. Starring T. Rex considers dinosaurs as a cultural phenomenon, seen as the interaction of three factors paleontological discoveries, the cultural interest these discoveries awaken, and the possibilities they offer for commercial exploitation. Jose Luis Sanz explains that the knowledge generated by paleontologists enters popular culture at a mythological level and that the mass communication media (for example, science fiction literature, comic books, television, and movies) are the vehicles that link science and its reflection in culture.

Sanz first analyzes the historical origins of the dinosaur myth in modern society. He then considers the manner in which information drawn from scientific study enters popular consciousness, discussing, among other things, the coexistence of men and dinosaurs, what dinosaurs looked like, extinction, the presence of dinosaurs in fantasy stories, and the relationship between dinosaurs and dragons."

Introduction by Stephen Jay Gould

In the geological record, there are five major mass extinctions—the "Big Five." The most famous happened at the end of the Cretaceous Period, when the dinosaurs and two-thirds of all marine animal species were wiped out, opening the door for the age of mammals and the rise of Homo Sapiens. Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.

This is the first major book to present a comprehensive overview of the current state of extinction studies. At the end of the journey, Raup has put forward the best science of the day to answer the question posed by the title: Bad genes or bad luck?

"An eminently entertaining and informative read." —Malcolm W. Browne, New York Times Book Review

"A delightful little book about life on this planet and about extinctions, in particular. It is as much about the philosophy and methodology of science as about the downside of evolution." —Clark R. Chapman, Planetary Science Institute

"David Raup's Extinction will change the way many of us perceive our world. In a style that is both elegant and persuasive, Raup undercuts the popular and comfortable notions that extinction is a mark of failure. . . . We are shown a world that is less certain, but in many ways more interesting than the one we imagined we occupied." —Roger Lewin, author of Bones of Contention

Lucid, nontechnical study presents the absorbing human, scientific and political dramas involved in the discovery and reconstruction of the gigantic reptiles, birds and other creatures who roamed the prehistoric West. Much of the book is devoted to the work of Othniel Charles Marsh and Edward Drinker Cope, two brilliant 19th-century paleontologists whose discoveries revolutionized the discipline, but whose bitter feud is legendary. "Excellently written...highly recommended..."--Science Books. 51 halftones. Bibliography.

With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot?
"Evolutionary Patterns" demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development.
