The authors argue that the growth pattern and form of the colony in many bryozoans is an adaptive strategy rather than a stable genetic character. "Bryozoan Evolution is profusely illustrated and has a bibliography of over 400 titles. It will find an appreciative audience of paleontologists, invertebrate zoologists, and ecologists thanks to its innovative and detailed evaluations of the roles of ecology, adaptive and functional morphology, life histories, biomechanics, developmental constraints, and chance on the evolution of the marine taxa of this speciose group."--Russel L. Zimmer, Science "This book is an excellent source of information on the functional morphology and variety of colonial architecture in bryozoans, very well illustrated, and worth reading at least twice."-Robert L. Anstey, Paleobiology "Even as one of the converted, I found the book a stimulating combination of paleobiology and ecology. In many ways it is a 'teaser'-the authors suggest a number of interesting hypotheses, and can test only some of them. Perhaps most important, McKinney and Jackson provide a plethora of fascinating ideas and examples that demonstrate the potential of this group of animals, and that should stimulate more work."-Michael S. Keough, TREE "This stimulating book is sure to promote further interest in bryozoans. It will appeal to biologists and paleontologists alike."-Paul Taylor, Times Higher Education Supplement

In this volume the author examines the pervasive pattern of alternation of structure and height of vertebral neural spines in the context of a larger review of axial structure in the most terrestrial of primitive Permo-Carboniferous tetrapods. He concludes that a coupled pattern of axial dorsiflexion and rotation played a significant role in primitive terrestrial locomotion.

Frozen mammals of the Ice Age, preserved for millennia in the tundra, have been a source of fascination and mystery since their first discovery over two centuries ago. These mummies, their ecology, and their preservation are the subject of this compelling book by paleontologist Dale Guthrie. The 1979 find of a frozen, extinct steppe bison in an Alaskan gold mine allowed him to undertake the first scientific excavation of an Ice Age mummy in North America and to test theories about these enigmatic frozen fauna.
The 36,000-year-old bison mummy, coated with blue mineral crystals, was dubbed "Blue Babe." Guthrie conveys the excitement of its excavation and shows how he made use of evidence from living animals, other Pleistocene mummies, Paleolithic art, and geological data. With photographs and scores of detailed drawings, he takes the reader through the excavation and subsequent detective work, analyzing the animal's carcass and its surroundings, the circumstances of its death, its appearance in life, the landscape it inhabited, and the processes of preservation by freezing. His examination shows that Blue Babe died in early winter, falling prey to lions that inhabited the Arctic during the Pleistocene era.
Guthrie uses information gleaned from his study of Blue Babe to provide a broad picture of bison evolutionary history and ecology, including speculations on the interactions of bison and Ice Age peoples. His description of the Mammoth Steppe as a cold, dry, grassy plain is based on an entirely new way of reading the fossil record.

Paleoethnobotany offers powerful tools for reconstructing past cultures by examining the interaction of human populations with the plant world. Plant remains from archaeological sites can provide information for a number of disciplines: archaeologists may use such remains to examine how plants were used, how agriculture changed over time, or how plant offerings in burials signaled social status; ecologists and botanists may use them to study morphological changes in plants due to domestication.
Combining case studies and theoretical discussions, Current Paleoethnobotany presents the first full discussion of the major stages and problems of paleoethnobotanical research, from designing and testing equipment, such as flotation machines, to quantification and interpretation. The volume explores a wide range of issues concerning collection techniques, analytical procedures, and interpretive models that will provide accurate information about past human societies from plant remains. The contributors offer data on specific regions as well as more general background information on the basic techniques of paleoethnobotany for the nonspecialist. Throughout, they explicitly examine the assumptions underlying paleoethnobotanical methods and the ways in which those assumptions affect anthropological and ecological research questions.
Based on a symposium presented at the 1985 meeting of the Society for American Archaeology, Current Paleoethnobotany moves beyond a technique-oriented view of paleoethnobotany to successfully integrate current thinking about both procedures and research goals. The contributors demonstrate the potential value of the field of paleoethnobotany and open the way for further discussion and improvement.

Die Oberflache der Erde hat eine bewegte Geschichte hinter sich. So stabil uns manche grossraumigen Landschaftsstrukturen wie Gebirgszuge, Tiefebenen und Ozeane auch erscheinen mogen, so sehr hat sich das Antlitz der Erde doch im Laufe von Milliarden von Jahren immer wieder verandert. Und uberall trifft man auf die Spuren dieser unruhigen Vergangenheit. Richard Fortey ist ihr Chronist, und indem er uns an geologisch besonders interessante Statten fuhrt und deren Eigenheiten erlautert, lehrt er uns, das Wesen der Erde besser zu verstehen. Er zeigt, dass nicht nur die Gestalt der Erdoberflache, sondern auch die menschliche Kultur, die Naturgeschichte, ja sogar die Form unserer Stadte auf tieferen geologischen Prozessen beruhen. Die Reise beginnt an den Hangen des Vesuvs, wo Fortey die Geschichte dieser von Vulkanausbruchen gekennzeichneten Landschaft durch die Augen der Italiener des 15. Jahrhunderts, der Romer und - auf der Basis einzigartiger geologischer Befunde - der Menschen der Jungsteinzeit erzahlt. Und mit jeder neuen Geschichte, die er erzahlt, treten Verbindungen von der jungeren Vergangenheit zu langst vergessenen Zeiten zutage - bis tief hinab zu fernen geologischen Epochen, wenn er Plattenverschiebungen und die Bildung von alten Kontinenten und Meeren beschreibt. Nichts in diesem Buch scheint still zu stehen. Die Erdoberflache weitet sich und zieht sich wieder zusammen, Berge und Seen entstehen und vergehen, Kontinente driften umher und kollidieren. Unter Forteys kundiger Fuhrung erklimmen wir die Alpen, baden in den heissen Quellen Islands und tauchen hinab zum Meeresgrund. Wir erkunden die kahlen Felsen von Neufundland, klettern in bohmische Silberminen hinab, spazieren durch die uppigen Okosysteme von Hawaii, durchqueren die Salzebenen von Oman und schlendern am Andreas-Graben entlang. Forteys Beschreibungen der Schonheiten der Natur sind dabei so unvergesslich wie die besten Reiseberichte, seine Prosa ist so packend wie die eines Romanciers, und seine kristallklaren wissenschaftlichen Erklarungen sind faszinierend und oft uberraschend. Dieses wahrhaft tiefschurfende Buch wird Ihren Blick auf die Welt verandern - fur immer."

Assembles Kurten's seminal papers in one volume, not only making them available once again but at the same time presenting a number of concepts and methodological innovations as they were first conceived.

One of the first interdisciplinary discussions of taphonomy (the study of how fossil assemblages are formed) and paleoecology (the reconstruction of ancient ecosystems), this volume helped establish these relatively new disciplines. It was originally published as part of the influential Prehistoric Archeology and Ecology series. Taphonomy is plainly here to stay, and this book makes a first class introduction to its range and appeal.--Anthony Smith, Interdisciplinary Science Reviews

"A rich historical pastiche of 17th- and 18th-century philosophy, science, and religion."--G. Y. Craig, "New Scientist "
"This book, by a distinguished Italian historian of philosophy, is a worthy successor to the author's important works on Francis Bacon and on technology and the arts. First published in Italian (in 1979), it now makes available to English readers some subtly wrought arguments about the ways in which geology and anthropology challenged biblical chronology and forced changes in the philosophy of history in the early modern era. . . . [Rossi] shows that the search for new answers about human origins spanned many disciplines and involved many fascinating intellects--Bacon, Bayle, Buffon, Burnet, Descartes, Hobbes, Holbach, Hooke, Hume, Hutton, Leibniz, de Maillet, Newton, Pufendorf, Spinoza, Toland, and, most especially, Vico, whose works are impressively and freshly reevaluated here."--Nina Gelbart, " American Scientist

How does bison meat taste after being frozen for 30,000 years? Were Ice Age cave painters trying to create "art" or just record history? How did ancient oil spills occur, before there were oil companies to create them? Those are just some of the questions renowned paleontologist Bjorn Kurten answers in this collection of lighthearted essays on fossils, ancient life, and related topics. Written for the general reader, these lively pieces range from a look at how scientific theories are created to some new views of old myths. Among the topics Kurten examines are the history of the Mediterranean Sea, the origin of birds, the theory of plate tectonics (continental drift), and the discovery of Piltdown Man, the "missing link" fossil forgery that fooled scientists for more than 40 years.

And, true to its title, the book offers a humorous "recipe" for freezing a mammoth that is tundra-tested, if not totally foolproof. "You may have to expend a few hundred mammoths before everything works out," the reader is cautioned, "But there are plenty of them." (Although the author hasn't tasted the fruits of his mammoth recipe, he did feast on some ancient bison meat that dated from 30,000 years ago. Kurten described the taste as "agreeable.")

Throughout these essays Kurten brings the prehistoric world alive with enthusiasm and humor, emphasizing that paleontology is the study of those that lived long ago instead of those who are long dead. As he says, "Isn't it more fun to see a dinosaur as something that used to live, rather than as the monstrous heap of bones which it happens to be at present?"

Fish, or lower vertebrates, occupy the basal nodes of the vertebrate phylogeny, and are therefore crucial in interpreting almost every feature of more advanced vertebrates, including amphibians, reptiles, birds and mammals. Recent research focuses on combining evolutionary observations - primarily from the fish fossil record - with developmental data from living fishes, in order to better interpret evolutionary history and vertebrate phylogeny. This book highlights the importance of this research in the interpretation of vertebrate evolution, bringing together world-class palaeontologists and biologists to summarise the most interesting, current and cutting-edge topics in fish evolution and development. It will be an invaluable tool for researchers in early vertebrate palaeontology and evolution, and those particularly interested in the interface between evolution and development.

After the mass extinction of the dinosaurs 65 million years ago, mammals became the dominant terrestrial life form on our planet. Roaming the earth were spectacular beasts such as saber-toothed cats, giant mastodonts, immense ground sloths, and gigantic giraffe-like rhinoceroses. Here is the ultimate illustrated field guide to the lost world of these weird and wonderful prehistoric creatures. A woolly mammoth probably won't come thundering through your vegetable garden any time soon. But if one did, this would be the book to keep on your windowsill next to the binoculars. It covers all the main groups of fossil mammals, discussing taxonomy and evolutionary history, and providing concise accounts of the better-known genera and species as well as an up-to-date family tree for each group. No other book presents such a wealth of new information about these animals--what they looked like, how they behaved, and how they were interrelated. In addition, this unique guide is stunningly illustrated throughout with full-color reconstructions of these beasts--many never before depicted--along with photographs of amazing fossils from around the world. * Provides an up-to-date guidebook to hundreds of extinct species, from saber-toothed cats to giant mammoths * Features a wealth of color illustrations, including new reconstructions of many animals never before depicted* Demonstrates evolution in action--such as how whales evolved from hoofed mammals and how giraffes evolved from creatures with short necks* Explains how mass extinctions and climate change affected mammals, including why some mammals grew so huge

John H. Ostrom's expeditions to the Bighorn Basin of Wyoming and Montana in the 1960s resulted in discoveries and research that would change long-held concepts in paleontology. This fiftieth-anniversary edition of his now well-known description of the type specimen of Deinonychus antirrhopus revisits the work that redefined theropod dinosaurs as the intelligent, agile, and gregarious ancestors of modern birds and led in the late twentieth century to a renaissance in the study of dinosaurs and the evolution of flight.

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.

Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on earth. Without burrowing, the planet would be very different today. Many animal lineages alive now-including our own-only survived a cataclysmic meteorite strike 65 million years ago because they went underground. On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows, which altered whole ecosystems. Every day we walk on an earth filled with an under-ground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters: fires, droughts, storms, meteorites, global warmings-and coolings. In a book filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.

During the past forty-three years our Division of Zoology of the Royal Ontario Museum has been most active in collecting various species of animals throughout the Province of Ontario, with particular emphasis on the local fauna of the Toronto region. During this time a number of outstanding naturalists have not only made careful collections of animals, but have also recorded accurate observations on the species with which they were familiar. This publication, we most sincerely hope, will be the first of many similar contributions to the study of the distribution of the fauna of Ontario.

What was life like on our planet long before the early humans emerged? Paleontologist Dr. Mark P. Witton draws on the latest twenty-first century discoveries to re-create the appearances and lifestyles of extinct, fascinating species, the environments they inhabited, and the challenges they faced living on an ever-changing planet. A worthy successor to Charles Knight's beloved 1946 classic, Life through the Ages II takes us on an unforgettable journey through the evolution of life on Earth. Dozens of gorgeous color illustrations and meticulously researched, accompanying commentary showcase the succession of lost worlds, defining events, and ancient creatures that have appeared since the earth was formed, creating an indispensable guide to explore what came before us.

How can we bring together the study of genes, embryos and fossils? "Embryos in Deep Time" is a critical synthesis of the study of individual development in fossils. It brings together an up-to-date review of concepts from comparative anatomy, ecology and developmental genetics, and examples of different kinds of animals from diverse geological epochs and geographic areas. Can fossil embryos demonstrate evolutionary changes in reproductive modes? How have changes in ocean chemistry in the past affected the development of marine organisms? What can the microstructure of fossil bone and teeth reveal about maturation time, longevity and changes in growth phases? This book addresses these and other issues and documents with numerous examples and illustrations how fossils provide evidence not only of adult anatomy but also of the life history of individuals at different growth stages. The central topic of Biology today - the transformations occurring during the life of an organism and the mechanisms behind them - is addressed in an integrative manner for extinct animals.

'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.

Sauropod dinosaurs were the largest animals ever to walk the earth, and they represent a substantial portion of vertebrate biomass and biodiversity during the Mesozoic Era. The story of sauropod evolution is told in an extensive fossil record of skeletons and footprints that span the globe and 150 million years of earth history. This generously illustrated volume is the first comprehensive scientific summary of sauropod evolution and paleobiology. The contributors explore sauropod anatomy, detail its variations, and question the myth that life at large size led to evolutionary stagnation and eventual replacement by more "advanced" herbivorous dinosaurs. Chapters address topics such as the evolutionary history and diversity of sauropods; methods for creating three-dimensional reconstructions of their skeletons; questions of sauropod herbivory, tracks, gigantism, locomotion, reproduction, growth rates, and more. This book, together with the recent surge in sauropod discoveries around the world and taxonomic revisions of fragmentary genera, will shed new light on "nature's greatest extravagances."

Questo secondo volume prosegue la breve trattazione sulle catastrofi naturali. E la volta delle catastrofi dell acqua e dell aria, spesso sui giornali quando un uragano o un inondazione colpiscono il nostro pianeta. E anche delle minacce cosmiche, rare ma in grado di annientare la nostra civilta.

Vedremo quegli straordinari eventi di cui conosciamo l esistenza dallo studio degli strati geologici e dei fossili, ma la cui causa e ancora avvolta nel mistero. Si tratta delle estinzioni di massa, episodi in cui la biosfera e cambiata in maniera improvvisa e drammatica a causa di una catastrofe globale.

Tra un aneddoto e una digressione sulle basi scientifiche dei fenomeni e passando attraverso qualche caso di studio, si incuriosisce il lettore su un tema importante e coinvolgente.

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.
