"Peking Man," a cave man once thought a great hunter who had first tamed fire, was actually a composite of the gnawed remains of some fifty women, children, and men unfortunate enough to have been the prey of the giant cave hyena. Researching the famous fossil site of Dragon Bone Hill in China, scientists Noel T. Boaz and Russell L. Ciochon retell the story of the cave's unique species of early human, Homo erectus. Boaz and Ciochon take readers on a gripping scientific odyssey. New evidence shows that Homo erectus was an opportunist who rode a tide of environmental change out Africa and into Eurasia, puddle-jumping from one gene pool to the next. Armed with a shaky hold on fire and some sharp rocks, Homo erectus incredibly survived for over 1.5 million years, much longer than our own species Homo sapiens has been on Earth. Tell-tale marks on fossil bones show that the lives of these early humans were brutal, ruled by hunger and who could strike the hardest blow, yet there are fleeting glimpses of human compassion as well. The small brain of Homo erectus and its strangely unchanging culture indicate that the species could not talk. Part of that primitive culture included ritualized aggression, to which the extremely thick skulls of Homo erectus bear mute witness. Both a vivid recreation of the unimagined way of life of a prehistoric species, so similar yet so unlike us, and a fascinating exposition of how modern multidisciplinary research can test hypotheses in human evolution, Dragon Bone Hill is science writing at its best.

Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of Oland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil."

Made in Africa: Hominin Explorations and the Australian Skeletal Evidence describes and documents the largest collection of modern human remains in the world from its time period. These Australian fossils, which represent modern humans at the end of their great 20,000 km journey from Africa, may be reburied in the next two years at the request of the Aboriginal community. Part one of the book provides an overview of modern humans, their ancestors, and their journeys, explores the construct of human evolution over the last two and half million years, and defines the background to the first hominins and later modern humans to leave Africa, cross the world and meet other archaic peoples who had also travelled and undergone similar evolutionary pathways. Part two focuses on Australia and the evidence for its earliest people. The Willandra Lakes fossils represent the earliest arrivals and are the largest and most diverse late Pleistocene collection from this part of the world. Although twenty to twenty-five thousand years younger than the oldest archaeological site in Australia, they exemplify the migrating end-point of the human story that reflect a diversity and culture not recorded elsewhere in the world. Part three records the Willandra Lake Collection itself from a photographic and descriptive perspective. Evolutionary biologists and geneticists will find this book to be a valuable documentation of the 20,000 km hominid migration from Africa to the most distant parts of the world, and of the challenges and findings of the Willandra Lake Collection.

This symposium, held in Argentina in March 2003, commemorates Otto Nordenskjoeld's 1901 expedition, and pays tribute to the Swedish and Argentinian explorers who took on the challenge of early fieldwork in Patagonia and Antarctica. This theme is extended to include recent fieldwork in the natural sciences in the Archipelago of Tierra del Fuego, the Antarctic Peninsula and the sub-Antarctic seas, and celebrates the fruitfulness of continuing Swedish-Argentinian scientific cooperation. The symposium and associated activities took place in the cities of Buenos Aires, La Plata and Ushuaia (Tierra del Fuego), and this book includes a selection of the most significant contributions presented at the meeting.

The landscape of southwestern Wyoming around the ghost town of Fossil is beautiful but harsh; a dry, high mountain desert with cool nights and long, cold winters inhabited by a sparse mountain desert community. But during the early Eocene, more than fifty million years ago, it was a subtropical lake, surrounded by volcanoes and forests and teeming with life. Buried within the sun-baked limestone is spectacular evidence of the lush vegetation and plentiful fauna of the ancient past, a transitional ecosystem giving us clues to how North America recovered from a great extinction event that wiped out dinosaurs and the majority of all species on the planet. Paleontologists have been conducting excavations at Fossil Butte for more than 150 years, and with "The Lost World of Fossil Lake", one of the world's leading experts on the fossils from this spectacular locality takes readers on a fascinating journey through the history of the discovery and exploration of the site. Deftly mixing incredible color photographs of the remarkable fossils uncovered there with an explanation of their evolutionary significance, Lance Grande presents an unprecedented, comprehensive portrait of the site, its treasures, and what we've learned from them. Grande presents a broad range of fossilized organisms from Fossil Lake - from single-celled algae to palm trees to crocodiles - and together they make this long-extinct community come to life in all its diversity and splendor. A field guide and atlas round out the book, enabling readers to identify and classify the majority of the known fossils from the site. Lavishly produced in full color, "The Lost World of Fossil Lake" is a stunning reminder of the intellectual and physical beauty of scientific investigation-and a breathtaking window onto our planet's long-lost past.

This work is a detailed study of people and plants in Little Dixie, a seven-county region of central Missouri. Based on three summers of field research, Professor Nolan combines ethnoscience with folklore to document what and why people know about wild plants in this little-known section of the American Midwest. The book is organized around the cognitive and behavioral differences between local experts and 'novices' who gather wild plant foods and medicines regularly throughout the seasons in Little Dixie. Ethnobotanical knowledge is described as an ongoing interaction between ecology and cognition, under constant modification by shifting cultural beliefs about edibility, efficacy, and sensory appeal. As consumable resources and symbols of belonging, wild plants are detailed with ethnographic context and vivid pen-and-ink sketches. Wild Harvest in the Heartland will appeal to a broad audience of anthropologists, ethnobotanists, folklorists, and ecologists, and will provide a welcome resource for naturalists, conservationists, and outdoor enthusiasts.

Forensic Taphonomy and Ecology of North American Scavengers compiles research on vertebrate scavenging behavior from numerous academic fields, including ecology and forensic anthropology. Scavenging behavior can displace remains from their depositional context, confound postmortem interval estimation, destroy osteological markers, and inflict damage that mimics or disguises perimortem trauma. Consequently, the actions of vertebrate scavengers can significantly impact the medicolegal investigation of human remains. It is therefore critical when interpreting a death scene and its associated evidence that scavenging be recognized and the possible effects of scavenging behavior considered. This book is an ideal reference for both students and medicolegal professionals, serving as a field manual for the identification of common scavenging species known to modify human remains in North America. In addition, this book presents a framework to guide investigators in optimizing their approach to scavenged cases, promoting more complete recovery of human remains and the accuracy of forensic reconstructions of peri- and postmortem events.

This book provides an overview, research compendium and an introduction to the science of molecular paleontology, including literature overview for non-geochemists. Analytical methods employed are included as a part of each chapter that underpin this branch of paleontology and indeed geochemistry. The primary usefulness of this volume is for organic geochemists, molecular palaeontologists, and molecular archeologists. Researchers, graduate students and academics interested in astrobiology from a paleontological perspective may also find this to be valuable.

Chondrichthyans possess unique anatomical features compared to other vertebrates, in particular a fully cartilaginous skeleton and a permanently renewed dentition. These characteristics make the fossilization of whole bodies difficult and consequently their fossil record consists mainly of a large number of isolated teeth. The study of their dentition is therefore of primary interest for our understanding of the evolution of this group. Beyond the dental morphology, the structure of the tissues composing the dentition has proved an important source of information, sometimes difficult to interpret, on the eating habits and the paleobiology of these animals. This book makes a thorough review of the existing theories in this field of research as well as introducing new elements from more recent studies. Through close reference to the fossil record of ancient selachians it examines what the study of dental tissue in cartilaginous fish can tell us about the evolution and the past biology of these animals, as well as what we can learn about the evolution of teeth themselves.

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 fossil record of giant flightless birds extends back to the Late Cretaceous, more than 70 million years ago, but our understanding of these extinct birds is still incomplete. This is partly because the number of specimens available is sometimes limited, but also because widely different approaches have been used to study them, with sometimes contradictory results. This book summarizes the current knowledge of the paleobiology of seven groups of giant flightless birds: Dinornithiformes, Aepyornithiformes, Dromornithidae, Phorusrhacidae, Brontornithidae, Gastornithidae and Gargantuavis. The first chapter presents the global diversity of these birds and reviews the tools and methods used to study their paleobiology. Chapters 2 to 8 are each dedicated to one of the seven groups of extinct birds. Finally, a conclusion offers a global synthesis of the information presented in the book in an attempt to define a common evolutionary model.

The names given to the variety of man-like fossils known to scientists should reflect no more than scientific views of the nature of human evolution. However, often in the past these names have also reflected confusion regarding the basic principles of scientific nomenclature; and the matter has been further complicated by the many new finds of recent decades. It is the unique purpose of this book to clarify the present state of knowledge regarding the main lines of human evolution by expressing what is known (and what is surmised) about them in appropriate taxonomic language. The papers in this volume were prepared by the world's leading authorities on the subject, and were revised in the light of discussions at a remarkable conference held in Austria in 1962 under the auspices of the Wenner-Gren Foundation. The authors review first the meaning of taxonomic statements as such, and then consider the substance of our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behavior changes and selection pressures in evolutionary sequences. Ample illustrations, bibliographies and an index enhance the permanent reference value of the book, which will undoubtedly prove to be among the fundamental paleoanthropological works of our time.

This book presents a hypothesis and evidence that organisms promote and ecosystems maximize biodiversity. All species have a net positive effect on their environment, other species, and diversity. The sun is 30% hotter than when life began, but the temperature has been kept moderate by life. Life created high oxygen, the ozone layer, and fertile soil, a diverse, living system. No species evolves in isolation, and most evolution is coevolution. The nature and number of links between species are as important as species number. Eukaryotes coevolve with complex ecosystems of microbes with which they exchange genes. Genomes and intraspecific interactions both act to promote evolution and diversification. Viruses increase diversity of their hosts and cause macroevolutionary transitions. Key Features Life alters the Earth in ways that increase biodiversity All species make their environment better for other species and promote diversity Life created the life-friendly atmosphere, temperature, and soil of today

In the Miocene and Pliocene fossil shell beds of the eastern United States, the single most spectacular molluscan species radiation is seen in the ecphora shells (the Tribe Ecphorini). These bizarrely shaped gastropods, with their distinctive ribbed shell sculpture, represent a separate branch of the Subfamily Ocenebridae, Family Muricidae. Characteristically, these muricid gastropods are heavily ornamented with spiral ribs and cords and are considered some of the most beautiful and interesting groups of fossil mollusks found along the Atlantic Coastal Plain and Floridian Peninsula. The ecphoras are greatly sought after by fossil collectors. The ecphora faunas, and their individual species and subspecies, are illustrated and described in detail, along with photographs of ecphora-bearing geological units and in-situ specimens. The authors list the 67 known species and subspecies that are recognized as valid, arranged by the eight genera and five subgenera that encompass these taxa.

In 1898, a 19-year-old girl marched into the Natural History Museum and demanded a job. At the time, no women were employed there as scientists, but for the determined Dorothea Bate this was the first step in an extraordinary career as a pioneering explorer and fossil-hunter and the beginning of an association with the Museum that was to last for more than 50 years. As a young woman in the early 1900s she explored the islands of Cyprus, Crete and the little known Majorca and Menorca, braving parental opposition and considerable physical hardship and danger. In remote mountain caves and sea-battered cliffs, she discovered, against enormous odds, the fossil evidence of unique species of extinct fauna, previously unknown to science, including dwarf elephants and hippos, giant dormice and a strange small goat-like antelope. Thirty years later in Bethlehem, she excavated against a backdrop of violence and under the shadow of war. By the end of her life Dorothea had earned an international reputation as an expert in her field. 'Discovering Dorothea' captures the indomitable spirit of a woman who, against social pressure and in the face of physical hardship, devoted her life to discovery and deepened our knowledge of the natural world.

This book is a reprint of the fourth edition, published in 1989, of the Textbook of Pollen Analysis and is unique in its approach as it discusses both the practical and theoretical aspects of palynology. It uses palynological techniques as tools for solving problems in quaternary geology, ecology and archeology. This edition of this standard reference has the same objectives as the earlier ones but the objectives have been widened, particularly the archaeological. There are over 130 illustrations and the identification keys have been thoroughly revised and are now illustrated. "Will certainly benefit all in understanding the principles of pollen analysis. All students, palynologists and libraries should have it as a text book for reference." Marine Geology "Classic and much-used text book ... will remain an indispensable book for those interested in paleoecology and practicing pollen analysis." The New Phycologist "Unsurpassed in its restriction to basic principles, breadth of coverage, clarity of expression and emphasis on ecology." Review of Paleobotany and Palynology

Late Quaternary Environmental Change addresses the interaction between human agency and other environmental factors in the landscapes, particularly of the temperate zone. Taking an ecological approach, the authors cover the last 20,000 years during which the climate has shifted from arctic severity to the conditions of the present interglacial environment.
