Owen was the founder of the Natural History Museum, bringing the collections over from the British Museum. Although he was a supporter of evolutionary theory, he was reluctant to accept Darwin's version of evolution. This volume examines fossil evidence for change in species over time.

Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Radiolarians in the Sedimentary Record presents the current state of knowledge on fossil radiolarians. The author discusses the record, as well as new integrated taxonomic systems at the family level. The book provides comprehensive coverage of the fossil record of these unicellular organisms. It also discusses their important role in the history of the Earth and their development of the biosphere. This text will prove indispensable for graduate students and researchers in geology, oceanography and earth sciences.

"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.

Titus Lucretius Carus was probably born in the early first century B.C., and died in the year 55. Little is known of his life, although two tantalizing bits of gossip were passed on by St. Jerome: that he was poisoned by a madness-inducing aphrodisiac given him by his wife, and that his great poem "On the Nature of Things" was posthumously edited by Cicero. For the latter assertion, writes Anthony Esolen in his introduction to the present volume, there is little evidence, and none whatsoever for the former.

What does survive is a masterful poetic work that stands as the greatest exposition of Epicurean philosophy. Writing in the waning days of the Roman Republic--as Rome's politics grew individualistic and treacherous, its high-life wanton, its piety introspective and morbid--Lucretius sets forth a rational and materialistic view of the world which offers a retreat into a quiet community of wisdom and friendship.

Even to modern readers, the sweep of Lucretius's observations is remarkable. A careful observer of nature, he writes with an innocent curiosity into how things are put together--from the oceans, lands, and stars to a mound of poppy seeds, from the "applause" of a rooster's wings to the human mind and soul. Yet Lucretius is no romantic. Nature is what it is--fascinating, purposeless, beautiful, deadly. Once we understand this, we free ourselves of superstitious fears, becoming as human and as godlike as we can be. The poem, then, is about the universe and how human beings ought to live in it. Epicurean physics and morality converge.

Until now, there has been no adequate English verse translation of Lucretius's work. Anthony Esolen fills that gap with a version that reproduces--with remarkable faithfulness--the meaning, pace, and tone of the original Latin.

Here is a book that will introduce a new generation of readers to a thinker whose powers of observation and depth of insight remain fresh to the present day.

"Esolen has the rare gift of being both a fine poet and a lover of languages. His diction is poetic and natural; he has a fine ear for sound, and the translation benefits greatly from being read aloud--as Latin poetry was meant to be. This translation is clear and forceful. It can, and will, be read."--Kenneth J. Reckford, University of North Carolina, Chapel Hill

Ecologist Paul Colinvaux's past several years in the Amazon yield this manual written both in English and Portuguese. Consisting in part of illustrations of the principal pollen types that have been found and identified in the sediments of Amazonian lakes, this book should prove a useful tool for ecologists and climate modellers. The manual also contains brief reviews of pioneering pollen work in the Amazon to date, as well as sections on pollen methods, pollen statistics, paleoecology, and lake coring methods.

This volume offers comprehensive and up-to-date information on research in many different disciplines which give an overall insight into the environmental history of Africa.

This book is a collection of papers presented in the symposia, held in Beijing, on palaeontology and historical geology. The papers deal with different topics, providing information on Palaeobiogeography and Palaeoecology of Asian countries, their faunal content, and fossil preservation.

IDEAL, the International Decade for East African Lakes, is a ten-year multi-national, multi-disciplinary investigation of the biological, geological, chemical, and physical limnology of the East African Lakes, taking into special account the Great Lakes of the East African Rift Valley and the climatology and paleoclimatology of the Rift Valley itself. The selected papers in this book serve as baseline knowledge for this intensive examination, with most of the contributing authors already actively researching these lakes. The oldest in the world and the largest on the continent, the lakes are vital resources for the indigenous populations of their basins. They are unique not only in their diverse populations of endemic species of fish and invertebrates, but in their sensitivity to climatic change, unusual circulation dynamics and water-column chemistry in relation to higher altitudes, and continuous record of climatic change in tropical Africa. This volume provides an overview of our current knowledge of the lakes combined with the most recent results of specific research efforts by African, American, and European investigators. Included also are some discussions on the impact of man, as well as comprehensive bibliographies.

This exciting new textbook examines the concepts of evolution as the underlying cause of the rich diversity of life on earth-and our danger of losing that rich diversity. Written as a college textbook, The Diversity and Evolution of Plants introduces the great variety of life during past ages, manifested by the fossil record, using a new natural classification system. It begins in the Proterozoic Era, when bacteria and bluegreen algae first appeared, and continues through the explosions of new marine forms in the Helikian and Hadrynian Periods, land plants in the Devonian, and flowering plants in the Cretaceous. Following an introduction, the three subkingdoms of plants are discussed. Each chapter covers one of the eleven divisions of plants and begins with an interesting vignette of a plant typical of that division. A section on each of the classes within the division follows. Each section describes where the groups of plants are found and their distinguishing features. Discussions in each section include phylogeny and classification, general morphology, and physiology, ecological significance, economic uses, and potential for research. Suggested readings and student exercises are found at the end of each chapter.

Using a series of case studies, the book demonstrates the power of dynamic analysis as applied to the fossil record. Written in an engaging and informative style, Dynamic Paleontology outlines the best application of quantitative and other tools to critical problems in the paleontological sciences including such topics as analysis of the Cambrian Explosion and the question regarding the presence of life on Mars. The book considers how we think about certain types questions and shows how we can refine our approach to analysis right from the beginning of any particular research effort. The analytical tools presented here will have wide application to other fields of knowledge; as such the book represents a major contribution to our deployment of modern scientific method.

It is a widely held belief that a climax vegetation of closed forest systems covered the lowlands of Central and Western Europe before humans intervened in prehistoric times to develop agriculture. If this intervention had not taken place, it would still be there and so if left, the grassland vegetation and fields we see today would revert to its natural closed forest state, although with a reduced number of wild species. This book challenges this view, using examples from history, pollen analyses and studies on the ecology of tree and shrub species such as oak and hazel. It tests the hypotheses that the climax vegetation is a closed canopy forest against the alternative one in which species composition and succession of vegetation were governed by herbivores and that the Central and Western European lowlands were covered by a park-like landscape consisting of grasslands, scrub, solitary trees and groves bordered by a mantle and fringe vegetation. Comparative information from North America is also included, because the forests there are commonly regarded as being analogous to the primeval vegetation in Europe. This title is a revised, updated and expanded translation of book published in Dutch.

The consummate guide to the ultimate sabertooth. Few animals spark the imagination as much as the sabertooth cat Smilodon. With their incredibly long canines, which hung like fangs past their jaws, these ferocious predators were first encountered by humans when our species entered the Americas. We can only imagine what ice age humans felt when they were confronted by a wild cat larger than a Siberian tiger. Because Smilodon skeletons are perennial favorites with museum visitors, researchers have devoted themselves to learning as much as possible about the lives of these massive cats. This volume, edited by celebrated academics, brings together a team of experts to provide a comprehensive and contemporary view of all that is known about Smilodon. The result is a detailed scientific work that will be invaluable to paleontologists, mammalogists, and serious amateur sabertooth devotees. The book * covers all major aspects of the animal's natural history, evolution, phylogenetic relationships, anatomy, biomechanics, and ecology * traces all three Smilodon species across both North and South America * brings together original, unpublished research with historical accounts of Smilodon's discovery in nineteenth-century Brazil The definitive reference on these iconic Pleistocene mammals, Smilodon will be cited by researchers for decades to come.

Paleocological Research on Easter Island: Insights on Settlement, Climate Changes, Deforestation and Cultural Shifts examines the area's climatic and ecological history, a topic not usually addressed in other literature. The book provides a thorough and synthetic account of all paleoecological works developed to date, including the latest discoveries. Finally, it attempts to match paleoecological evidence with the results of other disciplines creating a multidisciplinary framework. This approach to the field is ideal for researchers, university professors and graduate students in a varied range of disciplines and subdisciplines, including ecology, paleoecology, paleoclimatology, biogeography, sedimentology, and paleontology. Users will find synthesized information on Easter Island from the last millennia that will help pave the way towards an integrated interdisciplinary vision of the island's environmental-ecological-cultural system as a complex functional unit. Human and environmental deterministic views are avoided and the Easter Island enigmas are analyzed under a holistic perspective of continuous feedbacks and synergies among the different components of the system.

Part of the Fossils and Strata Monograph Series from the Scandinavian University Press The published study, Orthacean and Strophomenid Brachiopods from the Lower Silurian of the Central Oslo Region, is part of an international series on stratigraphy and paleontology.

Spinster Mary Anning, uneducated and poor, was of the wrong sex, wrong class and wrong religion, but fate decreed that she was exactly the right person in the right place and time to pioneer the emerging science of palaeontology, the study of fossils. Born in Lyme Regis in 1799, Mary learned to collect fossils with her cabinet-maker father. The unstable cliffs and stealthy sea made the task dangerous but after her father died the sale of fossils sustained her family. Mary's fame started as an infant when she survived a lightning strike that killed the three adults around her. Then, aged twelve, she caught the public's attention when she unearthed the skeleton of a 'fish lizard' or Ichthyosaurus. She later found the first Plesiosaurus giganteus, with its extraordinary long neck associated with the Loch Ness monster, and, dramatically, she unearthed the first, still rare, Dimorphodon macronyx, a frightening 'flying dragon' with hand claws and teeth. Yet her many discoveries were announced to the world by male geologists like the irrepressible William Buckland and Sir Henry De La Beche and they often received the credit. In Jurassic Mary Patricia Pierce redresses this imbalance, bringing to life the extraordinary, little-known story of this determined and pioneering woman.

In early July 1899, an excavation team of paleontologists sponsored by Andrew Carnegie discovered the fossil remains in Wyoming of what was then the longest and largest dinosaur on record. Named after its benefactor, the Diplodocus carnegii-or Dippy, as it's known today-was shipped to Pittsburgh and later mounted and unveiled at the Carnegie Museum of Natural History in 1907. Carnegie's pursuit of dinosaurs in the American West and the ensuing dinomania of the late nineteenth century coincided with his broader political ambitions to establish a lasting world peace and avoid further international conflict. An ardent philanthropist and patriot, Carnegie gifted his first plaster cast of Dippy to the British Museum at the behest of King Edward VII in 1902, an impulsive diplomatic gesture that would result in the donation of at least seven reproductions to museums across Europe and Latin America over the next decade, in England, Germany, France, Austria, Italy, Russia, Argentina, and Spain. In this largely untold history, Ilja Nieuwland explores the influence of Andrew Carnegie's prized skeleton on European culture through the dissemination, reception, and agency of his plaster casts, revealing much about the social, political, cultural, and scientific context of the early twentieth century.

Determining the precise timing for the evolutionary origin of groups of organisms has become increasingly important as scientists from diverse disciplines attempt to examine rates of anatomical or molecular evolution and correlate intrinsic biological events to extrinsic environmental events. Molecular clock analyses indicate that many major groups are twice as old, or more, than a literal reading of the fossil record attests, implying that the fossil record is incomplete. Few paleontologists agree that the fossil record is inadequate, arguing instead that our understanding of the molecular clock is far from ideal. Telling the Evolutionary Time: Molecular Clocks and the Fossil Record represents a discussion between molecular biologists and paleontologists, in which they investigate the significance of competing sources of data, explain the nature of molecular clocks and the fossil record, and strive to develop compromise models that incorporate contradictory opinions. These are presented as a series of case studies dealing with many of the most important groups of complex organisms, such as protists, land plants, flowering plants, complex animals, chordates, vertebrates, tetrapods, and modern birds. Bringing fresh insight and various perspectives to a complicated argument, this book assembles all sides of the debate into one comprehensive text. It is a significant volume for research scientists and advanced students across the field of evolutionary biology.

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 is a new and completely rewritten edition of the well-known text "Microfossils" (first published in 1980) covering all the major microfossil groups, with information on taxonomy, phylogeny, ecology and palaeoecology. Particular attention is given to the uses of microfossils in environmental reconstruction and biostratigraphy. It contains numerous line and half-tone illustrations. It also emphasizes on practical applications of micropalaeontology. Only student-friendly micropaleontology text is available.

The Rhaetian Penarth Group includes the former Westbury Beds, Cotham Beds, and White Lias. It crops out in a narrow strip from the Devon and Dorset coast to the mouth of the Tees, and is particularly well known from the exposures along the Bristol Channel. This diverse suite of late Triassic sedimentary rocks is internationally famous for the fossils that it yields, most notably from the bone beds. Coverage is comprehensive, with separate chapters on foraminifera, gastropods, bivalves, crustaceans, insects, echinoderms, other invertebrates, conodonts, fish, tetrapods, trace fossils and plants. There are background chapters on sedimentology, stratigraphy and the formation of the bone beds. The guide is copiously illustrated with specimens from all major UK public collections of Penarth Group fossils illustrated on 26 plates and 30 text-figures. It will be of use both to collectors who want to know more about this diverse and interesting suite of fossils, as well as to students of geology who wish to understand their conditions of deposition and accumulation.

Big cats such as lions, tigers, leopards, and jaguars fascinate us like few other creatures. They are enduring symbols of natural majesty and power. Yet despite the magnetic appeal of the big cats, their origins and evolutionary history remain poorly understood-and human activity threatens to put an end to the big cats' glory. On the Prowl is a fully illustrated and approachable guide to the evolution of the big cats and what it portends for their conservation today. Mark Hallett and John M. Harris trace the origins of these iconic carnivores, venturing down the evolutionary pathways that produced the diversity of big cat species that have walked the earth. They place the evolution and paleobiology of these species in the context of ancient ecosystems and climates, explaining what made big cats such efficient predators and analyzing their competition with other animals. Hallett and Harris pay close attention to human impact, from the evidence of cave paintings and analysis of ancient extinctions up to present-day crises. Their engaging and carefully documented account is brought to life through Hallett's detailed, vivid illustrations, based on the most recent research by leading paleontologists. Offering a fresh look at the rise of these majestic animals, On the Prowl also makes a powerful case for renewed efforts to protect big cats and their habitats before it is too late.
