The Triassic period is generally viewed as the beginning of the Age of Dinosaurs. For paleontologists, however, it also marks the rise of the world's first modern land ecosystems.

Over the past three decades, extensive, worldwide fieldwork has led to the discovery of many new species of Triassic animals and plants, suggesting that faunal and floral changes already began in the Middle Triassic and were more protracted than previously thought. The Late Triassic is a pivotal time in the evolution of life on land, with many of the major groups of present-day vertebrates and insects first appearing in the fossil record. This book provides the first detailed overview of life on land during the Triassic period for advanced students and researchers. Noted vertebrate paleontologists Hans-Dieter Sues and Nicholas C. Fraser also review the biotic changes of this period and their possible causes.

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

Fresh insights into the ongoing fascination with dinosaurs and their place in 19th century American nationalism In 1801, the first complete mastodon skeleton was excavated in the Hudson River Valley, marking the climax of a century-long debate in America and Europe over the identity of a mysterious creature known as the American Incognitum. Long before the dinosaurs were discovered and the notion of geological time acquired currency, many citizens of the new republic believed this mythical beast to be a ferocious carnivore, capable of crushing deer and elk in its "monstrous grinders." During the American Revolution, George Washington and Thomas Jefferson avidly collected its bones; for the founding fathers, its massive jaws symbolized the violence of the natural world and the emerging nation's own dreams of conquest. Paul Semonin's lively history of this icon of American nationalism focuses on the link between patriotism and prehistoric nature. From the first fist-sized tooth found in 1705, which Puritan clergyman claimed was evidence of human giants, to the scientific racialism associated with the discovery of extinct species, Semonin traces the evangelical beliefs, Enlightenment thought, and Indian myths which led the founding fathers to view this prehistoric monster as a symbol of nationhood. Semonin also sees the mystery of the mastodon in early America as a cautionary tale about the first flowering of our narcissistic fascination with a prehistoric nature ruled by ferocious carnivores. As such, American Monster offers fresh insights into the genesis of the ongoing fascination with dinosaurs.

The field of paleoclimatology relies on physical, chemical, and biological proxies of past climate changes that have been preserved in natural archives such as glacial ice, tree rings, sediments, corals, and speleothems. Paleoclimate archives obtained through field investigations, ocean sediment coring expeditions, ice sheet coring programs, and other projects allow scientists to reconstruct climate change over much of earth's history.

When combined with computer model simulations, paleoclimatic reconstructions are used to test hypotheses about the causes of climatic change, such as greenhouse gases, solar variability, earth's orbital variations, and hydrological, oceanic, and tectonic processes. This book is a comprehensive, state-of-the art synthesis of paleoclimate research covering all geological timescales, emphasizing topics that shed light on modern trends in the earth's climate. Thomas M. Cronin discusses recent discoveries about past periods of global warmth, changes in atmospheric greenhouse gas concentrations, abrupt climate and sea-level change, natural temperature variability, and other topics directly relevant to controversies over the causes and impacts of climate change. This text is geared toward advanced undergraduate and graduate students and researchers in geology, geography, biology, glaciology, oceanography, atmospheric sciences, and climate modeling, fields that contribute to paleoclimatology. This volume can also serve as a reference for those requiring a general background on natural climate variability.

This book highlights the knowledge about landscapes and characteristics of the earliest hunter-gatherer lifeway in Southern Patagonia. It presents an analysis of the archaeological investigations carried out during three decades by an interdisciplinary team that involved archaeologists, anthropologists, paleontologists, geologists and specialists in pollen and diatoms. The database yielded was recovered from systematic survey and excavations from the Pleistocene and Holocene stratigraphic layers of the rockshelter known as AEP-1, Piedra Museo Locality, situated in the central plateau of Santa Cruz Province, Argentina. Piedra Museo is a unique place in the world of high academic interest with some of the earliest archaeological remains in the Americas. Researchers defined two strata and several Stratigraphic units in the site based on the sedimentological and pedological characteristics. The depositional zones contain archaeological remains that are interpreted as hunting events corresponding to two main different occasions in the human colonization of the region, and a third human occupation during the Middle Holocene. Last one occurred then of the massive rockshelter roof colapse. The faunal remains led to a new approach to the palaeoenvironmental evolution of this enclosed basin. This volume describes the management of lithic raw materials and social networks from first human occupation of the Patagonian region to territorial consolidation of hunter-gatherer societies.

The author describes forty-two fossil taxa recovered during a study of the San Timoteo Badlands that used magnetobiostratigraphy to develop a temporal framework for addressing the tectonic evolution of southern California over the last 6 million years. For the Pliocene, small mammals are an effective means of correlating a magnetostratigraphy to the Geomagnetic Polarity Time Scale when radioisotopic dates are unobtainable.

Snakes comprise nearly 4,000 extant species found on all major continents except Antarctica. Morphologically and ecologically diverse, they include burrowing, arboreal, and marine forms, feeding on prey ranging from insects to large mammals. Snakes are strikingly different from their closest lizard relatives, and their origins and early diversification have long challenged and enthused evolutionary biologists. The origin and early evolution of snakes is a broad, interdisciplinary topic for which experts in palaeontology, ecology, physiology, embryology, phylogenetics, and molecular biology have made important contributions. The last 25 years has seen a surge of interest, resulting partly from new fossil material, but also from new techniques in molecular and systematic biology. This volume summarises and discusses the state of our knowledge, approaches, data, and ongoing debates. It provides reviews, syntheses, new data and perspectives on a wide range of topics relevant to students and researchers in evolutionary biology, neontology, and palaeontology.

One of the leading textbooks in its field, Bringing Fossils to Life applies paleobiological principles to the fossil record while detailing the evolutionary history of major plant and animal phyla. It incorporates current research from biology, ecology, and population genetics, bridging the gap between purely theoretical paleobiological textbooks and those that describe only invertebrate paleobiology and that emphasize cataloguing live organisms instead of dead objects. For this third edition Donald R. Prothero has revised the art and research throughout, expanding the coverage of invertebrates and adding a discussion of new methodologies and a chapter on the origin and early evolution of life.

Today the Upper Thames Valley is a region of green pastures and well-managed farmland, interspersed with pretty villages and intersected by a meandering river. The discovery in 1989 of a mammoth tusk in river gravels at Stanton Harcourt, Oxfordshire, revealed the very different ancient past of this landscape. Here, some 200,000 years ago, mammoths, straight-tusked elephants, lions, and other animals roamed across grasslands with scattered trees, occasionally disturbed by small bands of Neanderthals. The pit where the tusk was discovered, destined to become a waste disposal site, provided a rare opportunity to conduct intensive excavations that extended over a period of 10 years. This work resulted in the recording and recovery of more than 1500 vertebrate fossils and an abundance of other biological material, including insects, molluscs, and plant remains, together with 36 stone artefacts attributable to Neanderthals. The well-preserved plant remains include leaves, nuts, twigs and large oak logs. Vertebrate remains notably include the most comprehensive known assemblage of a distinctive small form of the steppe mammoth, Mammuthus trogontherii, that is characteristic of an interglacial period equated with marine isotope stage 7 (MIS 7). Richly illustrated throughout, Mammoths and Neanderthals in the Thames Valley offers a detailed account of all these finds and will be of interest to Quaternary specialists and students alike.

Written for non-specialists, this detailed survey of dinosaur origins, diversity, and extinction is designed as a series of successive essays covering important and timely topics in dinosaur paleobiology, such as "warm-bloodedness," birds as living dinosaurs, the new, non-flying feathered dinosaurs, dinosaur functional morphology, and cladistic methods in systematics. Its explicitly phylogenetic approach to the group is that taken by dinosaur specialists. The book is not an edited compilation of the works of many individuals, but a unique, cohesive perspective on Dinosauria. Lavishly illustrated with hundreds of new, specially commissioned illustrations by John Sibbick, world-famous illustrator of dinosaurs, the volume includes multi-page drawings as well as sketches and diagrams. First edition Hb (1996): 0-521-44496-9 David E. Fastovsky is Professor of Geosciences at the University of Rhode Island. Fastovsky, the author of numerous scientific publications dealing with Mesozoic vertebrate faunas and their ancient environments, is also scientific co-Editor of Geology. He has undertaken extensive fieldwork studying dinosaurs and their environments in Montana, North Dakota, Arizona, Mexico, and Mongolia. David B. Weishampel is a professor at the Center for Functional Anatomy and Evolution at Johns Hopkins University, School of Medicine. Weishampel is best known for discovering, researching, and naming several rare European dinosaur species. During the 1980s Weishampel gained fame for his work with American paleontologist Jack Horner and later named the famous plant-eating, egg-laying Orodromeus, Horner. Now, a decade after his pioneering studies with Horner, Weishampel is most widely known for his current work on the Romanian dinosaur fauna. He is the author and co-author of many titles, including The Dinosaur Papers, 1676-1906 (Norton, 2003); The Dinosauria, (University of California, 1990); and Dinosaurs of the East Coast, (Johns Hopkins University Press, 1996).

The Cambrian radiation was the explosive evolution of marine life that started 550,000,000 years ago. It ranks as one of the most important episodes in Earth history. This key event in the history of life on our planet changed the marine biosphere and its sedimentary environment forever, requiring a complex interplay of wide-ranging biologic and nonbiologic processes.

"The Ecology of the Cambrian Radiation" offers a comprehensive and surprising picture of the Earth at that ancient time. The book contains contributions from thirty-three authors hailing from ten countries and will be of interest to paleontologists, geologists, biologists, and other researchers interested in the global Earth-life system.

This book chronicles the earliest histories of familiar tropical Asian crops in the ancient Middle East and the Mediterranean, from rice and cotton to citruses and cucumbers. Drawing on archaeological materials and textual sources in over seven ancient languages, The Tropical Turn unravels the breathtaking anthropogenic peregrinations of these familiar crops from their homelands in tropical and subtropical Asia to the Middle East and the Mediterranean, showing the significant impact South Asia had on the ecologies, dietary habits, and cultural identities of peoples across the ancient world. In the process, Sureshkumar Muthukumaran offers a fresh narrative history of human connectivity across Afro-Eurasia from the Bronze Age to the late centuries BCE.

Seismosaurus: The Earth Shaker is a richly illustrated telling of the trials and triumphs of the discovery and excavation of Seismosaurus hallorum, the longest dinosaur yet known - and possibly the largest land animal ever to have lived. This is the first book to explain clearly the science used by paleontologists and the new cutting-edge techniques that led to Seismosaurus's discovery. David Gillette's first-person account of the project answers the most frequently asked questions about Seismosaurus: How was it discovered? How do we know it is a new species? How was it named? And more intriguing still, how did it die? His chronicle also examines the sauropods in general - the giant dinosaurs that with Seismosaurus include Apatosaurus (Brontosaurus), Brachiosaurus, and Diplodocus. This lively tale of discovery is woven with anecdotes and descriptions of the details of the excavation, which began with small jackhammers and later incorporated such sophisticated machinery as ground-penetrating radar that "looks" for fossils underground with radio waves. The story moves from the excavation site in 1985 to current advances in research and then back to the prehistoric age as Gillette, in adventure-narrative style, describes the habitat, habits, and characteristics of the sauropod, right down to Seismosaurus's gastroliths - stomach stones that helped in digestion. Part catalogue of the workings of paleontological science in the 1990s, the book also illustrates the exciting collaboration between David Gillette and the chemists and physicists who helped to reconstruct Seismosaurus and its life. Excavation of the Seismosaurus skeleton was completed in the fall of 1993. Some bones are already ondisplay at the New Mexico Museum of Natural History. Meanwhile, Mark Hallett, a consultant on Steven Spielberg's Jurassic Park, brings Seismosaurus to life in more than eighty marvelous color and black-and-white illustrations. Seismosaurus: The Earth Shaker is a delight!

Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines. The literature of paleobiology, in particular, is littered with qualifiers and cautions about applying the term to the fossil record or equating such species with those recognized among living organisms. In Species and Speciation in the Fossil Record, experts in the field examine how they conceive of species of fossil animals and consider the implications these different approaches have for thinking about species in the context of macroevolution. After outlining views of the Modern Synthesis of evolutionary disciplines and detailing the development within paleobiology of quantitative methods for documenting and analyzing variation within fossil assemblages, contributors explore the challenges of recognizing and defining species from fossil specimens and offer potential solutions. Addressing both the tempo and mode of speciation over time, they show how with careful interpretation and a clear species concept, fossil species may be sufficiently robust for meaningful paleobiological analyses. Indeed, they demonstrate that the species concept, if more refined, could unearth a wealth of information about the interplay between species origins and extinctions, between local and global climate change, and greatly deepen our understanding of the evolution of life.

"Fossils are the fragments from which, piece by laborious piece, the great mosaic of the history of life has been constructed. Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this-the greatest biography of all-is one in whose closing pages we find ourselves."-from Origins In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies. Rhodes's accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

Fossils, and the life of the past that they represent, are themes of great interest to the general public. This book identifies and describes essentially all publicly accessible, interpreted plant and animal fossil localities in the western half of Canada and the United States -- from Manitoba to Texas and westward. These are educationally oriented sites where the public may visit proven fossil localities, normally see fossils in place or in on-site collections, and learn about the geology and palaeontology of the site or region. Section 1 provides geological and biological contexts for the area and sites covered in the book. Section 2, which occupies the greatest part of the volume, describes and provides access information about the individual sites. Section 3 identifies sources of additional information about the sites and the subject matter reviewed in the first section. These sources include museum exhibits, pertinent literature! , sources of fossil replicas, and organised field experiences in palaeontology open to the public.

Breathtaking in scope, this is the first survey of the entire
ecological history of life on land2;from the earliest traces
of terrestrial organisms over 400 million years ago to the
beginning of human agriculture. By providing myriad insights
into the unique ecological information contained in the
fossil record, it establishes a new and ambitious basis for
the study of evolutionary paleoecology of land ecosystems.
A joint undertaking of the Evolution of Terrestrial
Ecosystems Consortium at the National Museum of Natural
History, Smithsonian Institution, and twenty-six additional
researchers, this book begins with four chapters that lay out
the theoretical background and methodology of the science of
evolutionary paleoecology. Included are a comprehensive
review of the taphonomy and paleoenvironmental settings of
fossil deposits as well as guidelines for developing
ecological characterizations of extinct organisms and the
communities in which they lived. The remaining three
chapters treat the history of terrestrial ecosystems through
geological time, emphasizing how ecological interactions have
changed, the rate and tempo of ecosystem change, the role of
exogenous "forcing factors" in generating ecological change,
and the effect of ecological factors on the evolution of
biological diversity.
The six principal authors of this volume are all associated
with the Evolution of Terrestrial Ecosystems program at the
National Museum of Natural History, Smithsonian Institution.

Written for everyone fascinated by the huge beasts that once roamed the earth, this book introduces the giant hornless rhinoceros, Indricotherium. These massive animals inhabited Asia and Eurasia for more than 14 million years, about 37 to 23 million years ago. They had skulls 6 feet long, stood 22 feet high at the shoulder, and were twice as heavy as the largest elephant ever recorded, tipping the scales at 44,100 pounds. Fortunately, the big brutes were vegetarians. Donald R. Prothero tells their story, from their discovery just a century ago to the latest research on how they lived and died.

Barthelemy Faujas de Saint-Fond (1741 1819) abandoned the legal profession to pursue studies in natural history. Appointed a royal commissioner of mines in 1785, he also served as professor of geology at the natural history museum in Paris from 1793 until his death. His keen interest in rocks, minerals and fossils led to a number of important discoveries, among which was confirmation that basalt was a volcanic product. The present work appeared in three parts between 1803 and 1809. The first volume features an introductory discussion of the current state of geology, before going on to consider the fossils of plants, shells, fish, cetaceans, crocodiles, and various mammalian quadrupeds. Of related interest in the history of geology, Mineralogie des volcans (1784) and the revised English edition of A Journey through England and Scotland to the Hebrides in 1784 (1907) are two other works by Faujas which are also reissued in this series."
