In paleontology there are certain encounters considered breakthroughs. Occasionally a unique event is discovered that permanently impacts our interpretation of an entire species. The Waco Mammoth Site represents one such landmark moment. At the edge of the city, mammoth skeletons were unearthed from twelve feet of overburden, a find that has since been called one of the most important ancient proboscidean sites in the world. The discovery was made in 1978 by Paul Barron and Eddie Bufkin with subsequent excavations by David Lintz, who along with volunteers from Baylor University's Strecker Museum conducted the initial investigations. George Naryshkin, in his senior thesis for Baylor University's Department of Geology, identified the five partial skeletons as Mammuthus columbi. Work was halted at the site from 1981 until Calvin Smith became the director of the Strecker Museum in 1983 and reopened the excavations in 1984. By the end of that year there were a total of sixteen specimens exposed in a cluster resembling a herd dying from a singular event. A news conference held by Baylor's Department of Public Relations received an enormous amount of interest that resulted in international coverage. Many colleagues contacted the museum wanting to see the site. Among them was Dr. Gary Haynes, who had done extensive research on both extinct and modern elephants through the National Geographic Society and the Smithsonian Institution. When he visited the site, he confirmed that it contained a nursery herd that succumbed to a single event, making it the largest such accumulation known to the scientific community. During the next few years, the site was expanded and new discoveries unearthed: a forty-five-year-old female trying to extricate a juvenile out of the mud flow, as well as the herd bull with a juvenile on top of his tusks, a first in prehistoric mammoth behavior. In 2015, after thirty-seven years of preservation and perseverance—and a whole lot of work and support from numerous individuals, especially volunteer Mr. Ralph Vinson, as well as many other organizations and entities—and at the proposal of the National Park Service, the site was federally recognized as the Waco Mammoth National Monument.
This is a personal account of the human side of Everett C Olson's distinguished career as a palaeobiologist. Origins and the combination of events that led to a formal education at the University of Chicago, the selection of a career, and an interest in the Permian are reviewed. Then Olson vividly describes two decades of field work in Texas, emphasising the people, places and events that he and his co-workers encountered there at mid-century. The second half of the book is devoted to Olson's pioneering efforts in establishing and strengthening ties between palaeontologists of the US and USSR during the Cold War years and especially his deepening friendship with Professor Ivan A Efremov. Olson and Efremov, two scientists from different cultures, wrestled with opposing philosophies but shared common interests and emotions. This book will certainly be of interest to the many people who have known Dr Olson as colleague, mentor, and friend. For the general reader, the book provides insights into the career of a distinguished contemporary scientist and represents an important chapter in the 20th century history of palaeontology, earth science, and international scientific relations.
Human life, and how we came to be, is one of the greatest scientific and philosophical questions of our time. This compact and accessible book presents a modern view of human evolution. Written by a leading authority, it lucidly and engagingly explains not only the evolutionary process, but the technologies currently used to unravel the evolutionary past and emergence of Homo sapiens. By separating the history of palaeoanthropology from current interpretation of the human fossil record, it lays numerous misconceptions to rest, and demonstrates that human evolution has been far from the linear struggle from primitiveness to perfection that we've been led to believe. It also presents a coherent scenario for how Homo sapiens contrived to cross a formidable cognitive barrier to become an extraordinary and unprecedented thinking creature. Elegantly illustrated, Understanding Human Evolution is for anyone interested in the complex and tangled story of how we came to be.
Fossils have been vital to our understanding of the formation of the earth and the origins of all life on it. However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this delightful book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are 'living fossils'? What fossils will we leave behind for future generations to examine? Building on the scientific aspects, he places fossils in a very human context, highlighting their impact on philosophy and mythology, our concept of time, and today's popular culture. What quickly becomes obvious is that the discovery of fossils and the ways in which they have been interpreted over time makes for fascinating reading. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
The horned dinosaurs, a group of rhinoceros-like creatures that lived 100 to 65 million years ago, included one of the greatest and most popular dinosaurs studied today: Triceratops. Noted for his flamboyant appearance--marked by a striking array of horns over the nose and eyes, a long bony frill at the back of the head, and an assortment of lumps and bumps for attracting females--this herbivore displayed remarkable strength in its ability to fight off Tyrannosaurus rex. It was also among the last dinosaurs to walk the earth. In telling us about Triceratops and its relatives, the Ceratopsia, Peter Dodson here re-creates the sense of adventure enjoyed by so many scientists who have studied them since their discovery in the mid-nineteenth century. From the badlands of the Red Deer River in Alberta to the Gobi Desert, Dodson pieces together fossil evidence to describe the ceratopsians themselves--their anatomy, biology, and geography--and he evokes the human dimension of their discovery and interpretation. An authoritative survey filled with many original illustrations, this book is the first comprehensive presentation of horned dinosaurs for the general reader. Dodson explains first the fascinating ways in which the ceratopsians dealt with their dangerous environment. There follows a lesson on ceratopsian bone structure, which enables the reader quickly to grasp the questions that still puzzle scientists, concerning features such as posture, gait, footprints, and diet. Dodson evenhandedly discusses controversies that continue, for example, over sexual dimorphism and the causes of the dinosaurs' disappearance. Throughout his narrative, we are reminded that dinosaur study is a human enterprise. We meet the scientists who charmed New York high society into financing expeditions to Mongolia, home of Triceratops' predecessors, as well as those who used their poker winnings to sustain paleontology expeditions. Rich in fossil lore and in tales of adventure, the world of the Ceratopsia is presented here for specialists and general readers alike. Originally published in 1998. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
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.
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 Open Access volume highlights how tree ring stable isotopes have been used to address a range of environmental issues from paleoclimatology to forest management, and anthropogenic impacts on forest growth. It will further evaluate weaknesses and strengths of isotope applications in tree rings. In contrast to older tree ring studies, which predominantly applied a pure statistical approach this book will focus on physiological mechanisms that influence isotopic signals and reflect environmental impacts. Focusing on connections between physiological responses and drivers of isotope variation will also clarify why environmental impacts are not linearly reflected in isotope ratios and tree ring widths. This volume will be of interest to any researcher and educator who uses tree rings (and other organic matter proxies) to reconstruct paleoclimate as well as to understand contemporary functional processes and anthropogenic influences on native ecosystems. The use of stable isotopes in biogeochemical studies has expanded greatly in recent years, making this volume a valuable resource to a growing and vibrant community of researchers.
Paleoecology is a discipline that uses evidence from fossils to provide an understanding of ancient environments and the ecological history of life through geological time. This text covers the fundamental approaches that have provided the foundation for present paleoecological understanding, and outlines new research areas in paleoecology for managing future environmental and ecological change. Topics include the use of actualism in paleoecology, development of paleoecological models for paleoenvironmental reconstruction, taphonomy and exceptional fossil preservation, evolutionary paleoecology and ecological change through time, and conservation paleoecology. Data from studies of invertebrates, vertebrates, plants and microfossils, with added emphasis on bioturbation and microbial sedimentary structures, are discussed. Examples from marine and terrestrial environments are covered, with a particular focus on periods of great ecological change, such as the Precambrian-Cambrian transition and intervals of mass extinction. Readership: This book is designed for advanced undergraduates and beginning graduate students in the earth and biological sciences, as well as researchers and applied scientists in a range of related disciplines.

A series of illustrations depict dinosaurs in the their natural habitat, and an appendix lists museums and other major repositories of tracks and replicas, and gives details on tracksites open to the public. Includes annotated references and detailed descriptions of important specimens, describing how these trackways can help interpret behavior.
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.
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.
Millions of years ago in the Cretaceous period, the mighty Tyrannosaurus rex--with its dagger-like teeth for tearing its prey to ribbons--was undoubtedly the fiercest carnivore to roam the Earth. Yet as "What Bugged the Dinosaurs?" reveals, T. rex was not the only killer. George and Roberta Poinar show how insects--from biting sand flies to disease-causing parasites--dominated life on the planet and played a significant role in the life and death of the dinosaurs. The Poinars bring the age of the dinosaurs marvelously to life. Analyzing exotic insects fossilized in Cretaceous amber at three major deposits in Lebanon, Burma, and Canada, they reconstruct the complex ecology of a hostile prehistoric world inhabited by voracious swarms of insects. The Poinars draw upon tantalizing new evidence from their amazing discoveries of disease-producing vertebrate pathogens in Cretaceous blood-sucking flies, as well as intestinal worms and protozoa found in fossilized dinosaur excrement, to provide a unique view of how insects infected with malaria, leishmania, and other pathogens, together with intestinal parasites, could have devastated dinosaur populations. A scientific adventure story from the authors whose research inspired "Jurassic Park," "What Bugged the Dinosaurs?"? offers compelling evidence of how insects directly and indirectly contributed to the dinosaurs' demise.
Cetaceans (whales, dolphins, and porpoises) have fascinated and bewildered humans throughout history. Their mammalian affinities have been long recognized, but exactly which group of terrestrial mammals they descend from has, until recently, remained in the dark. Recent decades have produced a flurry of new fossil cetaceans, extending their fossil history to over 50 million years ago. Along with new insights from genetics and developmental studies, these discoveries have helped to clarify the place of cetaceans among mammals, and enriched our understanding of their unique adaptations for feeding, locomotion and sensory systems. Their continuously improving fossil record and successive transformation into highly specialized marine mammals have made cetaceans a textbook case of evolution - as iconic in its own way as the origin of birds from dinosaurs. This book aims to summarize our current understanding of cetacean evolution for the serious student and interested amateur using photographs, drawings, charts and illustrations.

Animals as geomorphic agents have primarily been considered "curiosities" in the literature of geomorphology, whose spatial and quantitative influences have been seen as both limited and minor. Zoogeomorphology: Animals as Geomorphic Agents examines the distinct geomorphic influences of invertebrates, ectothermic vertebrates, birds, and mammals, and demonstrates the importance of animals as landscape sculptors. Specific processes associated with the diversity of animal influences in geomorphology are examined, including burrowing and denning, nesting, lithophagy and geophagy, wallowing and trampling, food caching, excavating for food, and dam building by beavers. Particular emphasis is placed on terrestrial animals, although aquatic animals are also discussed where appropriate. This book, which is the only one available wholly devoted to this topic, will interest graduate students and professional research workers in geomorphology, ecology, environmental science, physical geography, and geology.
Land bridges are the causeways of biodiversity. When they form, organisms are introduced into a new patchwork of species and habitats, forever altering the ecosystems into which they flow; and when land bridges disappear or fracture, organisms are separated into reproductively isolated populations that can evolve independently. More than this, land bridges play a role in determining global climates through changes to moisture and heat transport and are also essential factors in the development of biogeographic patterns across geographically remote regions. In this book, paleobotanist Alan Graham traces the formation and disruption of key New World land bridges and describes the biotic, climatic, and biogeographic ramifications of these land masses' changing formations over time. Looking at five land bridges, he explores their present geographic setting and climate, modern vegetation, indigenous peoples (with special attention to their impact on past and present vegetation), and geologic history. From the great Panamanian isthmus to the boreal connections across the North Atlantic and North Pacific Oceans that allowed exchange of organisms between North America, Europe, and Asia, Graham's sweeping, one-hundred-million-year history offers new insight into the forces that shaped the life and land of the New World.
Xiaoming Wang and Richard H. Tedford have spent the past 20 years studying the evolutionary history of the family Canidae. Both are well known for having established the modern framework for the evolutionary relationship of canids. Combining their research with Mauricio Ant?n's impeccable reconstructions of both extinct and extant species, Wang and Tedford present a remarkably detailed and nuanced portrait of the origin and evolution of canids over the past 40 million years. The authors cull their history from the most recent scientific research conducted on the vast collections of the American Museum of Natural History and other leading institutions. The fossil record of the Canidae, particularly those from their birth place in North America, are the strongest of their kind among known groups of carnivorans. Such a wonderfully detailed evolutionary history provides access to a natural history that is not possible with many other groups of carnivorans. With their rich fossil record, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behavior and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach in this book is the perfect accompaniment to an extremely important branch of animal and fossil study. It transforms the science of paleontology into a thrilling visual experience and provides an unprecedented reference for anyone fascinated by dogs.
"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.
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.
The study of volcano-ice interactions, or 'glaciovolcanism', is a field experiencing exponential growth. This comprehensive volume presents a discussion of the distinctive processes and characteristics of glaciovolcanic eruptions, their products, and landforms, with reference to both terrestrial and Mars occurrences. Supported by abundant diagrams and photos from the authors' extensive collections, this book outlines where eruptions have occurred and will occur in the future on Earth, the resulting hazards that are unique to volcano-ice interactions, and how the deposits are used to unravel planetary palaeoclimatic histories. It has a practical focus on lithofacies, glaciovolcanic edifice morphometry and construction, and applications to palaeoenvironmental studies. Providing the first global summary of past and current work, this book also identifies those areas in need of further research, making this an ideal reference for academic researchers and postgraduate students, in the fields of volcanology, glaciology, planetary science and palaeoenvironmental studies.
The transition from the Eocene to the Oligocene epochs was the most significant event in earth history since the extinction of dinosaurs. As the first Antarctic ice sheets appeared, major extinctions and faunal turnovers took place on the land and in the sea, eliminating forms adapted to a tropical world and replacing them with the ancestors of most of our modern animal and plant life. Through a detailed study of climatic conditions and of organisms buried in Eocene-Oligocene sediments, this volume shows that the separation of Antarctica from Australia was a critical factor in changing oceanic circulation and ultimately world climate. In this book forty-eight leading scientists examine the full range of Eocene and Oligocene phenomena. Their articles cover nearly every major group of organisms in the ocean and on land and include evidence from paleontology, stable isotopes, sedimentology, seismology, and computer climatic modeling. The volume concludes with an update of the geochronologic framework of the late Paleogene. Originally published in 1992. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
