This book presents the first overview of the Toarcian Oceanic Anoxic Event in the southern Iberian paleomargin, in the western Tethys. The study of catastrophic events that affected the ecosystems in the past is of great interest, because it offers the possibility of establishing models that can be applied to current and future environmental changes. The book provides comprehensive information on the changes in marine ecosystems in connection with a global massive extinction, the Early Toarcian, and with the deposition of black shales, global warming and a disruption of the carbon cycle. In addition, the book describes the incidence of this event in this part of the Tethys close to the connection with the Protoatlantic, the Hispanic Corridor. Special attention is paid to sedimentological and ichnological aspects, fossil content (macroscopic and microscopic), and geochemistry. It also presents the facies changes related to fragmentation of the shelf and the evolution to hemipel agic troughs and swells in this paleomargin. Lastly, it characterizes this anoxic event in under-researched outcrops from southern Spain and compares the findings with those in well-known sections from northern and central Europe. This book offers a unique resource for all researchers interested in the Toarcian Oceanic Anoxic Event, but also in oceanic anoxic events that occurred during the Mesozoic in general, because of their similarity to recent climatic changes.

From the outback of Australia to the Gobi Desert of Mongolia and the savanna of Madagascar, the award-winning science writer and dinosaur enthusiast John Pickrell embarks on a world tour of new finds, meeting the fossil hunters who work at the frontier of discovery. He reveals the dwarf dinosaurs unearthed by an eccentric Transylvanian baron; an aquatic, crocodile-snouted carnivore bigger than T. rex that once lurked in North African waterways; a Chinese dinosaur with wings like a bat; and a Patagonian sauropod so enormous it weighed more than two commercial jet airliners. Other surprising discoveries hail from Alaska, Siberia, Canada, Burma, and South Africa. Why did dinosaurs grow so huge? How did they spread across the world? Did they all have feathers? What do sauropods have in common with 1950s vacuum cleaners? The stuff of adventure movies and scientific revolutions, Weird Dinosaurs examines the latest breakthroughs and new technologies that are radically transforming our understanding of the distant past. Pickrell opens a vivid portal to a brand-new age of fossil discovery, in which fossil hunters are routinely redefining what we know and how we think about prehistory's most iconic and fascinating creatures.

In the days when dinosaurs dominated the earth, their marine counterparts--every bit as big and ferocious--reigned supreme in prehistoric seas. In this entrancing book, Richard Ellis, one of the world's foremost writers on the denizens of the deep, takes us back to the Mesozoic era to resurrect the fascinating lives of these giant seagoing reptiles.

Working from the fossil record, Ellis explores the natural history of these fierce predators, speculates on their habits, and tells how they eventually became extinct--or did they? He traces the 200-million-year history of the great ichthyosaurs, plesiosaurs, and mosasaurs who swam the ancient oceans--and who, according to some, may even still frequent the likes of Loch Ness.

Picture if you will seventy-foot dragons with foot-long serrated teeth, or an animal that looked like a crocodile crossed with a shark the size of a small yacht. With its impossibly long neck, Plesiosaurus conybeari has been compared to "a giant snake threaded through the body of a turtle." At a length of nearly sixty feet, Mosasaurus hoffmanni boasted powerful jaws and teeth that could crunch up even the hardest-shelled giant sea turtle. And Kronosaurus queenslandicus, perhaps the most formidable of the lot, had a skull nine feet long--more than twice that of Tyrannosaurus Rex--with teeth to match.

The first book about these amazing animals in nearly a century, "Sea Dragons" draws upon the most recent scientific research to vividly reconstruct their lives and habitats. Their fossils have been found all over the world--in Europe, Australia, Japan, and even Kansas--in lands that once lay on the floors of Jurassic and Triassic seas. Along the way, the book also provides intriguing insights into and entertaining tales about the work, discoveries, and competing theories that compose the fascinating world of vertebrate paleontology.

Ellis also graces his text with a set of incomparable illustrations. Widely hailed as our foremost artist of marine natural history, he depicts vividly how these creatures probably appeared and, through these likenesses, invites us to speculate on their locomotion, their predatory habits, their very lifestyles.

A genuine book of marvels and wonders, "Sea Dragons" will certainly stir one's curiosity about our planet's prehistoric past.

In 1980, the science world was stunned when a maverick team of researchers proposed that a massive meteor strike had wiped the dinosaurs and other fauna from the Earth 66 million years ago. Scientists found evidence for this theory in a "crater of doom"on the Yucatan Peninsula that showed our planet has been the target in a galactic shooting gallery. Seeking to develop "neocatastrophism" even further, Michael R. Rampino adds to this exciting field in Cataclysms, building on the latest findings from leading geoscientists. Rampino recounts his conversion to the impact hypothesis, describing his visits to meteor-strike sites and his review of the existing geological record. His story enables a richer understanding of the science behind major planetary upheavals and extinction events. The new geology he outlines explicitly rejects nineteenth-century "uniformitarianism," which casts planetary change as gradual and driven by processes we can see at work today. Rampino's new geology offers a cosmic context for Earth's geologic evolution, in which cataclysms from above in the form of comets and asteroid impacts and from below in the form of huge outpourings of lava in flood-basalt eruptions have led to severe changes in the Earth's surface. The new geology sees Earth's position in our solar system and galaxy as the keys to understanding our planet's geology and history of life. The author concludes with a fascinating take on dark matter's potential as a triggering mechanism, considering its role in heating Earth's core and spurring massive volcanism throughout geologic time.

The discovery of stunning, feathered dinosaur fossils coming out of China since 2006 suggest that these creatures were much more bird-like than paleontologists previously imagined. Further evidence-bones, genetics, eggs, behavior, and more-has shown a seamless transition from fleet-footed carnivores to the ancestors of modern birds. Mixing colorful portraits with news on the latest fossil findings and interviews with leading paleontologists in the United States, China, Europe, and Australia, John Pickrell explains and details dinosaurs' development of flight. This special capacity introduced a whole new range of abilities for the animals and helped them survive a mass extinction, when thousands of other dinosaur species that once populated the Earth did not. Pickrell also turns his journalistic eye toward the stories behind the latest discoveries, investigating the role of the Chinese black market in trading fossils, the controversies among various dinosaur hunters, the interference of national governments intent on protecting scientific information, and the race to publish findings first that make this research such a dynamic area of science.

This book presents the results of a unique macroscopic and radiological analysis, by X-ray and CT scan, of the bone pathologies of about 1800 subjects who lived at the time of the Roman Empire (first and second centuries A.D.) and whose remains were recovered during the excavation of a suburban necropolis of Rome. The survey, which represents a collaboration between the Italian Society of Orthopaedics and Traumatology and the Special Superintendent for the Archaeological Heritage of Rome, has yielded incredible images of different orthopaedic diseases in a period when no surgical treatment was available: there are cases of infection (osteomyelitis), metabolic disease (gout), hematologic disease (multiple myeloma), traumatic lesions and their complications and degenerative pathology (osteoarthritis, particularly secondary and overload). A multidisciplinary team including orthopaedists, paleopathologists, radiologists and medical historians has evaluated the major groups of bone disease in the population finding out incredible cases and picture of ortho-traumatologic pathologies in a pre-surgical era. The homogeneity of the sample and the number of subjects make this a study of fundamental importance.

This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.

The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how important a role the integument plays in the locomotion of many marine vertebrates.  This involves the crossed-fiber architecture, which was first discovered in a classic study on nemertean worms. As a design principle we see that the crossed-fiber architecture is ubiquitous in nature. Research on some of the most dynamic marine vertebrates of the oceans – tuna, dolphins and sharks, and the extinct Jurassic ichthyosaurs – shows precisely how the crossed-fiber architecture contributes to high-speed swimming  and (in lamnid sharks) may even aid in energy conservation.  However, this design principle is not restricted to animals in the marine biota but is also found as far afield as the dinosaurs and, most recently, has been revealed as a major part of the microstructure of the most complex derivative of the integument, the feather. We see that a variety of phylogenetically diverse vertebrates take to the air by using skin flaps to glide from tree to tree or to the ground, and present detailed descriptions of innovations developed in pursuit of improved gliding capabilities in both extinct and modern day gliders. But the vertebrate integument had even greater things in store, namely true or flapping flight. Pterosaurs were the first vertebrates to use the integument as a membrane in true flapping flight and these interesting extinct animals are discussed on the basis of past and cutting-edge research , most intriguingly with respect to the structure of the flight membrane. Bats, the only mammals that fly, also employ integumental flight membranes. Classic research on bat flight is reviewed and supplemented with the latest research, which shows the complexities of the wing beat cycle to be significantly different from that of birds, as revealed by particle image velocimetry. The book’s largest chapter is devoted to birds, given that they make up nearly half of the over 22,000 species of tetrapods. The flight apparatus of birds is unique in nature and is described in great detail, with innovative research highlighting the complexity of the flight structures, bird flight patterns, and behavior in a variety of species. This is complimented by new research on the brains of birds, which shows that they are more complex than previously thought. The feather made bird flight possible, and was itself made possible by β-keratin, contributing to what may be a unique biomechanical microstructure in nature, a topic discussed in some depth. A highly polarized subject concerns the origin of birds and of the feather. Alleged fossilized protofeathers (primal simple feathers) are considered on the basis of histological and taphonomic investigative studies in Chapter 6. Finally, in Chapter 7 we discuss the controversies associated with this field of research. Professor Theagarten Lingham-Soliar works at the Nelson Mandela Metropolitan University, Port Elizabeth and is an Honorary Professor of Life Sciences at the University of KwaZulu-Natal.

This book addresses the principles and methods for determining petroleum source rocks based on fossil spores and pollen. Studying petroliferous basins in China, we discovered that there are often as many as three different sources of the microfossils: the source rocks, the rocks along the pathway, and the reservoir rocks. Therefore, fossil spores, pollen and algae from inland and coastal shelf petroliferous basins are analyzed and illustrated to show this complex process. Furthermore, the organic origin theory of oil is proven and environmental characteristics for hydrocarbon source-rock formation are discussed. Along with the geochronical and geographic distribution of non-marine petroleum source rocks in China, the mechanisms of petroleum migration following the pathways to the reservoirs are investigated. It will be a valuable reference work as well as a textbook for a wider research areas ranging from stratigraphy, palynology, palaeontology and petroleum geology.

This book celebrates the contributions of Dr. Frederick S. Szalay to the field of Mammalian Evolutionary Morphology. Professor Szalay is a strong advocate for biologically and evolutionarily meaningful character analysis. He has published about 200 articles, six monographs, and six books on this subject. This book features subjects such as the evolution and adaptation of mammals and provides up-to-date articles on the evolutionary morphology of a wide range of mammalian groups.

This book brings together eastern and western scholarship on a controversial subject: a catastrophic inundation of the Pontic basin which might have inspired the biblical story of Noah's flood. In 35 papers, many previously unavailable in English, experts in oceanography, marine geology, paleoclimate, paleoenvironment, archaeology, and linguistic spread offer data and arguments for or against the flood hypothesis. Appendices include 600 radiocarbon dates from the region, obtained by USSR and western labs.

This unparelleled reference synthesizes the methods used in microfacies analysis and details the potential of microfacies in evaluating depositional environments and diagenetic history, and, in particular, the application of microfacies data in the study of carbonate hydrocarbon reservoirs and the provenance of archaeological materials. Nearly 230 instructive plates (30 in color) showing thin-section photographs with detailed explanations form a central part of the content. Helpful teaching-learning aids include detailed captions for hundreds of microphotographs, boxed summaries of technical terms, many case studies, guidelines for the determination and evaluation of microfacies criteria, self-testing exercises for recognition and characterization skills, and more

The vertebrate integument arose about 450 million years ago as an 'armour' of dermal bony plates in small, jawless fish-like creatures, informally known as the ostracoderms. This book reviews the major changes that have occurred in the vertebrate integument from its beginnings to the present day. Critical questions concerning the origin, structure and functional biology of the bony integument are discussed and intrinsically linked to major steps in vertebrate evolution and phylogeny-the origin of jaws and the origin of teeth. The discussions include the origins of mineralization of major vertebrate skeletal components such as the dermatocranium, branchial arches and vertebral column. The advances that led to the origin of modern fishes and their phylogenetic development are reviewed and include the evolution of fins and replacement of the bony plates with several types of dermal scales. The evolution of reptiles saw a major transformation of the integument, with the epidermis becoming the protective outermost layer, from which the scales arose, while the dermis lay below it. The biological significance of the newly-evolved -keratin in reptilian scales, among the toughest natural materials known, is discussed in the context of its major contribution to the great success of reptiles and to the evolution of feathers and avian flight. The dermis in many vertebrates is strengthened by layers of oppositely oriented cross-fibres, now firmly entrenched as a design principle of biomechanics. Throughout the book conventional ideas are discussed and a number of new hypotheses are presented in light of the latest developments. The long evolutionary history of vertebrates indicates that the significance of the Darwinian concept of "survival of the fittest" may be overstated, including in our own mammalian origins and that chance often plays a major role in evolutionary patterns. Extensive illustrations are included to support the verbal descriptions. Professor Theagarten Lingham-Soliar is in the Department of Life Sciences at the University of KwaZulu-Natal.

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.

This book provides a novel focus on adaptive explanations for cranial and postcranial features and functional complexes, socioecological systems, life history patterns, etc. in early primates. It further offers a detailed rendering of the phylogenetic affinities of such basal taxa to later primate clades as well as to other early/recent mammalian orders. In addition to the strictly paleontological or systemic questions regarding Primate Origins, the editors concentrate on the adaptive significance of primate characteristics. Thus, the book provides the broadest possible perspective on early primate phylogeny and the adaptive uniqueness of the Order Primates.

Here, a diverse group of geologists and paleobiologists focus their attention on the richly fossiliferous Neogene stratigraphic sections of the Dominican Republic. They provide an updated geological framework and a series of novel studies of evolutionary stasis and change among different lineages and associated ecological communities. This collection of studies illustrates the immense potential of collaborative, multidisciplinary, and field-based paleobiological research.

This book presents the multidisciplinary results of an extensive underwater excavation in north Florida. This yielded the most complete results of interactions between early Paleoindians and late Pleistocene megafauna, in a rich environmental context in eastern North America. The data provides fundamental insights into "the Peopling of the Americas" and "The Extinction of the Megafauna". An excellent color photo section expresses the uniqueness of this project.

This monograph describes early Ordovician (Ibexian:Tremadocian early Floian) trilobites from Northern Spitsbergen from the section through the Kirtonryggen Formation adjacent to Hinlopen Strait. The Formation is divided into three Members, each with distinct trilobites collectively representing the fullest known succession from the Bathyurid biofacies of the eastern Laurentian carbonate platform. Previous research on the Ordovician of Spitsbergen is summarised and correlations with similar faunas previously described from Canada, Greenland, western Newfoundland, Vermont New York State, Oklahoma and Missouri are discussed. Taxonomic problems are discussed in detail leading to the recognition of 53 species, of which 15 are new, belonging to 31 genera including four new. Twenty-four taxa are described under open or tentative nomenclature. The lower Member yields the earliest known occurrences of the Illaenoidea, Proetoidea and Scutelluoidea, supporting the hypotheses relating the origin of new major clades to inshore habitats.

South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the "Great American Biotic Interchange" (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South America and continues today. The major phases of mammalian dispersal occurred from the Latest Pliocene (Marplatan Age) to the Late Pleistocene (Lujanian Age). The most important and richest localities of Late Miocene-Holocene fossil vertebrates of South America are those of the Pampean region of Argentina. There are also several Late Miocene and Pliocene localities in western Argentina and Bolivia. Other important fossils have been collected in localities of Pleistocene age outside Argentina: Tarija (Bolivia), karstic caves of Lagoa Santa and the recently explored caves of Tocantins (Brasil), Talara (Peru), La Carolina (Ecuador), Muaco (Venezuela), and Cueva del Milodon (Chile), among others. The book discusses basic information for interpreting the GABI such as taxonomic composition (incorporating the latest revisions) at classical and new localities for each stage addressing climate, environments, and time boundaries for each stage. It includes the chronology and dynamics of the GABI, the integration of South American mammalian faunas through time, the Quaternary mammalian extinctions and the composition of recent mammalian fauna of the continent.

From airplanes to birds, the phenomenon of flight has always amazed and mystified humans. Therefore, it is unsurprising that scientists have invested a substantial amount of research into unraveling the secrets of flight evolution. Over the course of the past decade, the science of flight evolution has recently experienced a research renaissance, most of the information has been confined to the ivory tower of academia. In On the Wing, David Alexander delves into the evolution of flight in each of the four animal groups that evolved powered flight: insects, pterosaurs, birds, and bats. Alexander presents and compares each group's evolutionary history, including diversification and partial or complete extinction, especially as related to flight. The evolution of flight in animals is fascinating story riddled with scientific controversy and colorful characters, from the incredible Archaeopteryx to the recently-discovered feathered dinosaur Microraptor. Chapter topics include aerodynamics, comparisons and contrasts among the powered flyers, and the ultimate evolution away from flight. Alexander even examines the surprisingly diverse group of gliding animals, including squirrels, snakes, and ants. Through rigorous yet accessible writing, Alexander offers a comprehensive and engaging account of the evolution of flight, from dinosaurs to modern birds. On the Wing will delight and inform everyone from bird lovers to dinosaur enthusiasts, and offers key insights into the perpetual mystery of flight.

Georges Cuvier (1769-1832), one of the founding figures of vertebrate palaeontology, pursued a successful scientific career despite the political upheavals in France during his lifetime. In the 1790s, Cuvier's work on fossils of large mammals including mammoths enabled him to show that extinction was a scientific fact. In 1812 Cuvier published this four-volume illustrated collection of his papers on palaeontology, osteology (notably dentition) and stratigraphy. It was followed in 1817 by his famous Le regne animal, available in the Cambridge Library Collection both in French and in Edward Griffith's expanded English translation (1827-35). Volume 3 of Recherches sur les ossemens fossiles recounts Cuvier's excitement at acquiring fossils from gypsum quarries near Paris, and the challenges of piecing the fragments together correctly. Cuvier describes the methodical reconstruction of the pachyderm fossils and lists other fossils occurring in the same rock formations: carnivores, an opossum, birds, reptiles, and fish.

Volume 4 of Recherches sur les ossemens fossiles focuses first on ruminants, horses and pigs. Cuvier then discusses fossils of carnivores, including bears, hyenas and big cats. The book concludes by describing fossil sloths, and the oviparous reptiles found in older strata, such as crocodiles, turtles, and marine dinosaurs.

Reconstructing the paleobiology of fossil non-human primates, this book is intended as an exposition of non-human primate evolution that includes information about evolutionary theory and processes, paleobiology, paleoenvironment, how fossils are formed, how fossils illustrate evolutionary processes, the reconstruction of life from fossils, the formation of the primate fossil record, functional anatomy, and the genetic bases of anatomy. Throughout, the emphasis of the book is on the biology of fossil primates, not their taxonomic classification or systematics, or formal species descriptions. The author draws detailed pictures of the paleoenvironment of fossil primates, including contemporary animals and plants, and ancient primate communities, emphasizing our ability to reconstruct lifeways from fragmentary bones and teeth, using functional anatomy, stable isotopes from enamel and collagen, and high resolution CT-scans of the cranium. Fossil Primates will be essential reading for advanced undergraduates and graduate students in evolutionary anthropology, primatology and vertebrate paleobiology.
