Picture a world of dog-sized scorpions and millipedes as long as a car; tropical rainforests with trees towering over 150 feet into the sky and a giant polar continent five times larger than Antarctica. That world was not imaginary; it was the earth more than 300 million years ago in the Carboniferous period of the Paleozoic era. In Carboniferous Giants and Mass Extinction, George R. McGhee Jr. explores that ancient world, explaining its origins; its downfall in the end-Permian mass extinction, the greatest biodiversity crisis to occur since the evolution of animal life on Earth; and how its legacies still affect us today. McGhee investigates the consequences of the Late Paleozoic ice age in this comprehensive portrait of the effects of ancient climate change on global ecology. Carboniferous Giants and Mass Extinction examines the climatic conditions that allowed for the evolution of gigantic animals and the formation of the largest tropical rainforests ever to exist, which in time turned into the coal that made the industrial revolution possible-and fuels the engine of contemporary anthropogenic climate change. Exploring the strange and fascinating flora and fauna of the Late Paleozoic ice age world, McGhee focuses his analysis on the forces that brought this world to an abrupt and violent end. Synthesizing decades of research and new discoveries, this comprehensive book provides a wealth of insights into past and present extinction events and climate change.

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

Illustrated Key to Skulls of Genera of North American Land Mammals is a manual that contains illustrations of North American land mammals such as marsupials, shrews, bats, moles among many others. This manual is a well-illustrated key, useful for identifying mammals through cranial characteristics. It also contains line-drawings, and many photographs to aid in identifying related genera. The distribution, diversity, and characteristics of each order and family of land mammals found in North American and to the north of Mexico are briefly discussed. J. Knox Jones, Jr., has been a practicing mammalogist for more than 40 years. Currently he is a Paul Whitfield Horn Professor of Biological Sciences at Texas Tech and a Curator in the Museum there. Jones has authored or edited 14 books among is more than 350 publications, and has studied mammals on five continents. He is a past president of the American Society of Mammalogists and has been awarded the C. Hart Merriam Award, the H. H. T. Jackson Award, and Honorary Membership by that society. In 1992, he was selected as Texas Distinguished Scientist of the Year by the Texas Academy of Science, and was awarded the Donald W. Tinkle Research Excellence Award by the Southwestern Association of Naturalists. Richard W. Manning is a member of the faculty of Southwest Texas State University in San Marcos. He has authored more than 40 publications, most of which deal with mammals. Manning has had considerable instructional experience in laboratories in mammalogy, and has been cited for his excellence in teaching. He is also an avid field biologist, and thus has studied mammals in their natural habitats as well. Manning took most of the photographs used in this laboratory manual and made many of the line drawings.

This edited volume explores the various views on the origins of tetrapods-amphibians, reptiles, birds, and mammals-views that agree or differ depending in part on how certain fossil animals are classified and which methodology is used for classification. Eighteen chapters by an international group of paleontologists and neontologists here present current hypotheses, emphasizing the kinds of data needed to answer controversial questions, as well as the variety of solutions that emerge from diferent analyses of the same data set. The book is arranged in five sections, each of which contains an overview essay that either describes the development of various schools of thought regarding the origin of the tetrapod group in question or critically summarizes the arguments presented in the section. The first section addresses the origins of tetrapods as a group, focusing on lobe-finned fishes and early tetrapods. Next is a section dealing with amphbians, followed by one on reptiles. The fourth section concerns avian origins, and the final section treats the origins and early diversification of mammals. With an overall goal of stimulating critical evaluation by the reader rather than providing unequivocal answers, this volume will be of particaular interest to vertebrate paleontologists, evolutionary morphologists, and ichthyological, herpatological, avian, and mammalian systematists.

Essays discuss size, time, the landscape, the world view of modern biology, two-dimensional animals, sabertooth tigers, evolution, and the scientific method.

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.

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.

Every day, in natural history museums all across the country, colonies of dermestid beetles diligently devour the decaying flesh off of animal skeletons that are destined for the museum's specimen collection. That time-saving process was developed and perfected at the University of Kansas Natural History Museum by Charles D. Bunker, a lowly assistant taxidermist who would rise to become the curator of recent vertebrates and who made an indelible mark on his field. That innovative breakthrough serves as a testament to the tenacity of a quietly determined naturalist. Bunker was part of the small team of men who constructed and installed the famous Panorama of North American Mammals, the centerpiece exhibit of the KU Natural History Museum located in Dyche Hall. That iconic building on the KU campus was expressly built to house the collection of mounted animals that impressed the world a decade earlier at the 1893 Chicago Columbian Exposition and World's Fair. Once the panorama was completed, Bunker turned his attention to field collecting. Bunker's field notes provide an accurate, authentic account of several expeditions to collect such specimens as well as a rare view of the extreme hardships of fieldwork in those early days. Perhaps most notable is "Bunk's" 1911 expedition to western Kansas, where he discovered the fossil remains of a forty-five-foot-long sea serpent-later identified as Tylosaurus proriger, an aquatic reptile from the mosasaur genus and the largest example of the species found in North America. In 2014, Tylosaurus was named the marine fossil of the state of Kansas. Birds, Bones, and Beetles tells the story of a man whose passion for learning led to remarkable discoveries, extraordinary exhibits, and the prestigious careers of many students he mentored in the natural sciences.

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.

From his stunning discovery of "Tyrannosaurus rex "one hundred years ago to the dozens of other important new dinosaur species he found, Barnum Brown led a remarkable life (1873OCo1963), spending most of it searching for fossilsOCoand sometimes oilOCoin every corner of the globe. One of the most famous scientists in the world during the middle of the twentieth century, BrownOCowho lived fast, dressed to the nines, gambled, drank, smoked, and was known as a ladiesOCO manOCobecame as legendary as the dinosaurs he uncovered. "Barnum Brown "brushes off the loose sediment to reveal the man behind the legend. Drawing on BrownOCOs field correspondence and unpublished notes, and on the writings of his daughter and his two wives, it discloses for the first time details about his life and travelsOCofrom his youth on the western frontier to his spying for the U.S. government under cover of his expeditions. This absorbing biography also takes full measure of BrownOCOs extensive scientific accomplishments, making it the definitive account of the life and times of a singular man and a superlative fossil hunter.

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.

The Paleobiological Revolution chronicles the incredible ascendance of the once-maligned science of paleontology to the vanguard of a field. With the establishment of the modern synthesis in the 1940s and the pioneering work of George Gaylord Simpson, Ernst Mayr, and Theodosius Dobzhansky, as well as the subsequent efforts of Stephen Jay Gould, David Raup, and James Valentine, paleontology became embedded in biology and emerged as paleobiology, a first-rate discipline central to evolutionary studies. Pairing contributions from some of the leading actors of the transformation with overviews from historians and philosophers of science, the essays here capture the excitement of the seismic changes in the discipline. In so doing, David Sepkoski and Michael Ruse harness the energy of the past to call for further study of the conceptual development of modern paleobiology.

The paleoecological history of the Americas is as complex as the region is broad: stretching from the Arctic Circle to Tierra del Fuego, the New World features some of the most extraordinary vegetation on the planet. But until now it has lacked a complete natural history. Alan Graham remedies that with "A Natural History of the New World." With plants as his scientific muse, Graham traces the evolution of ecosystems, beginning in the Late Cretaceous period (about 100 million years ago) and ending in the present, charting their responses to changes in geology and climate. By highlighting plant communities' roles in the environmental history of the Americas, Graham offers an overdue balance to natural histories that focus exclusively on animals. Plants are important in evolution's splendid drama. Not only are they conspicuous and conveniently stationary components of the Earth's ecosystems, but their extensive fossil record allows for a thorough reconstruction of the planet's paleoenvironments. What's more, plants provide oxygen, function as food and fuel, and provide habitat and shelter; in short, theirs is a history that can speak to many other areas of evolution. "A Natural History of the New World "is an ambitious and unprecedented synthesis written by one of the world's leading scholars of botany and geology.

As recently as 11,000 years ago--"near time" to geologists--mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, "Twilight of the Mammoths "presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.
As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation--both in our thinking about what is "natural" and in the natural world itself.

Earth's climate has undergone dramatic changes over the geologic timescale. At one extreme, Earth has been glaciated from the poles to the equator for periods that may have lasted millions of years. At another, temperatures were once so warm that the Canadian Arctic was heavily forested and large dinosaurs lived on Antarctica. Paleoclimatology is the study of such changes and their causes. Studying Earth's long-term climate history gives scientists vital clues about anthropogenic global warming and how climate is affected by human endeavor.

In this book, Michael Bender, an internationally recognized authority on paleoclimate, provides a concise, comprehensive, and sophisticated introduction to the subject. After briefly describing the major periods in Earth history to provide geologic context, he discusses controls on climate and how the record of past climate is determined. The heart of the book then proceeds chronologically, introducing the history of climate changes over millions of years--its patterns and major transitions, and why average global temperature has varied so much. The book ends with a discussion of the Holocene (the past 10,000 years) and by putting manmade climate change in the context of paleoclimate.

The most up-to-date overview on the subject, "Paleoclimate" provides an ideal introduction to undergraduates, nonspecialist scientists, and general readers with a scientific background.

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."

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.

South America is home to some of the most distinctive mammals on Earth—giant armadillos, tiny anteaters, the world's largest rodent, and its smallest deer. But the continent once supported a variety of other equally intriguing mammals that have no close living relatives: armored mammals with tail clubs, saber-toothed marsupials, and even a swimming sloth. We know of the existence of these peculiar species thanks to South America's rich fossil record, which provides many glimpses of prehistoric mammals and the ecosystems in which they lived. Organized as a "walk through time" and featuring species from 15 important fossil sites, this book is the most extensive and richly illustrated volume devoted exclusively to the Cenozoic mammals of South America. The text is supported by 75 life reconstructions of extinct species in their native habitats, as well as photographs of fossil specimens and the sites highlighted in the book. An annotated bibliography is included for those interested in delving into the scientific literature.

Darriwilian to Sandbian Graptolites from Northwest China provides information on the exquisite, mostly-pyritic graptolites of middle to late Ordovician from North China and Tarim, China. These locations have developed the most complete successions of strata and fossil records of the time in the world. It provides the first systematic account of the renowned graptolite faunas with over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone, with plentiful elaborate figures, camera-lucida illustrations and color photos of graptolites.

The book presents many aspects of the graptolites during the critical transition from middle to late Ordovician, including new morphologies, classification of latest convention, diversity change and evolutions, and based on which a refined biostratigraphy divisions and correlation with other major regions or continents. The book is useful for paleontologists, stratigraphic specialists, petroleum geologists, and graduate students of various fields in geology.

"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"
