A survey of representative trilobite species from North America. It includes meticulous line drawings of 42 species, with information for each concerning classification, geologic range, and geographical distribution. Descriptions of probable life style, similar species, interesting features, etc. are also given. The 8 page, illustrated Introduction includes discussions of trilobite anatomy, growth, vision, lifestyles, locomotion, feeding, classification, and extinction. A brief "suggested reading" list is also offered.

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.

The great dinosaur bone beds of the American and Canadian West are world famous and have yielded spectacular fossil finds. But the eastern United States and maritime Canada, where dinosaurs also roamed in great numbers, have been equally important to the study of these extraordinary creatures. Some dinosaur fossils have come from the bog iron and clay pits of Maryland and New Jersey, while others have been discovered in the riverbanks of North and South Carolina. Dinosaur footprint sites have been found from central Virginia to the Bay of Fundy in Nova Scotia.

In "Dinosaurs of the East Coast," David Weishampel and Luther Young restore East Coast dinosaurs to their rightful place on the paleontological map. They describe such dinosaurs as the plant-eating "Astrodon johnstoni," which browsed in a tropical Maryland jungle 100 million years ago; "Anchisaurus polyzelus," which lived in New England some 200 million years ago; "Eubrontes," the first large therapod on the East Coast; "Pekinosaurus olseni," a primitive ornithischian found in North Carolina; and "Hadrosaurus foulkii," a duck-billed dinosaur that lived in New Jersey some 70 million years ago. In addition, they chronicle the long and colorful history of dinosaur fossil hunting along the Atlantic coast and profile the modern-day fossil hunters--both professional paleontologists and amateur collecters--who continue to make important discoveries today. Richly illustrated with more than one hundred photographs and drawings, "Dinosaurs of the East Coast" combines science and history to offer a new look at an always fascinating subject.

Some 111 million years ago, deep in the heart of Texas, a herd of twenty-ton dinosaurs sauntered across a wet mud flat. Their footprints eventually became frozen in stone, leaving a sign of one fleeting moment of a particular day in the lives of these magnificent creatures. Today, after mountains of time have passed, the story of dinosaurs in what is now Texas is being reconstructed, footprint by footprint, bone by bone. Lone Star Dinosaurs tells that story, along with the exciting tale of the discoveries that have opened a peephole into the past. Behind each fossil find, there is not just a dinosaur but a person-- sometimes a child--whose spark of curiosity lights the picture of prehistory. This is a thrilling story, engagingly written and beautifully illustrated, through which young and old alike can enter the world of the dinosaurs and the world of the dinosaur hunters. Dinosaurs are a Texas legacy from worlds long past. Pleurocoelus, Alamosaurus, Acrocanthosaurus, Chasmosaurus, Tyrannosaurus, and Tenontosaurus are among the representatives Texas boasts of every basic group of dinosaurs--a remarkable diversity that samples nearly the entire range of dinosaurian development over an immense expanse of time. In fact, the three dinosaur-bearing areas within the state--the Panhandle, Central Texas, and Big Bend--yield treasures of vastly different ages, from the beginning of the Mesozoic Era more than 200 million years ago to the time of the big extinction some 66 million years ago. These dinosaurs lived in such different arrangements of the continents and oceans that they may as well have lived in different worlds. Their stories offer a compelling picture of the history of life on our planet.

As a novel endeavour in ecological science, this book focuses on a major issue in organismal life on Earth: species coexistence. The book crosses the usual disciplinary boundaries between palaeobiology, ecology and evolutionary biology and provides a timely overview of the patterns and processes of species diversity and coexistence on a range of spatio-temporal scales. In this unique synthesis, the author offers a critical and penetrating examination of the concepts and models of coexistence and community structure, thus making a valuable contribution to the field of community ecology. There is an emphasis on clarity and accessibility without sacrificing scientific rigour, making this book suitable for both advanced students and individual researchers in ecology, palaeobiology and environmental and evolutionary biology.
Comprehensive and contemporary synthesis.
Pulls together the aggregate influence of evolution and ecology on patterns in communities.
Balanced mix of theory and empirical work.
Clearly structured chapters with short introduction and summary.

Pokines uses the terrestrial mammalian microfauna from the site of El Juyo (Santander, Spain) and related sites to reconstruct the palaeoenvironment of Cantabrian Spain. A new method of reconstruction is presented, based on the relative proprtions of these microfauna, and the human ecological adaptations of the Upper Palaeolithic in Cantabrian Spain are examined as they relate to the resulting interpretation of the palaeoenvironment.

Theoretical morphology--which seeks to sketch the range of forms that biological entities could take, with the ultimate goal of discovering why certain forms exist but others do not--is among paleontology's most significant contributions to the understanding of evolution. Today, with the aid of computers in developing conceivable morphologies, the discipline has been able to advance into a remarkable tool for the study of evolution. Yet despite these advances, the field remains largely untapped and ripe with research potential. In this volume, paleontologist George McGhee presents the first complete overview of the field, its advancements in recent years, and the challenges ahead.

"Theoretical Morphology" provides readers with the background they need to launch their own research. McGhee describes the steps involved in defining the geometric parameters (theoretical morphospaces) for an organic form in order to generate a spectrum of other possible forms that have never actually appeared. He also addresses the simulation of actual processes of morphogenesis, with the goal of attaining a more nuanced comprehension of how evolutionary processes work.

"Theoretical Morphology" takes readers through a variety of theoretical morphospaces including those for univalved, bivalved, discrete, and branching growth systems. With a glossary of terms and a comprehensive list of references on the subject, this is an excellent handbook for graduate students or professional scientists interested in employing these cutting-edge techniques in their own research.

A re-evalutation of the chronology and archaeology of the Late glacial of the north-western Ardennes, and an identification of human modification of faunal assemblages from five cave sites. The final chapter is an exploration of the ethnicity of butchery.

Just 12,000 years ago - at the height of the last Ice Age - saber-toothed tigers, giant ground sloths, camels, hippos and the great herds of proboscideans: giant mastodons and mammoths, extinct relatives of the elephant, roamed the land where skyscrapers now stand. Why are these splendid creatures no longer with us? This compelling book explores the reasons for these extinctions and provides a tour of mass extinctions throughout earth's history, including the great comet crash that killed off the dinosaurs. Brilliantly written, The Call of Distant Mammoths is an engaging exploration of the history of life and the importance of humanity as an evolutionary force.

This flora of 70 species is dominated by deciduous trees, many with descendants in China. Precipitation was 890 mm, mean annual temperature 12.5 C, the annual range 10 C, and freezing rare. Elevation was about 1000 meters. Comparison with the Horse Prairie flora, 30 miles east and across the present continental divide, indicates that the divide was then low and discontinuous, with warmer climate to the east.

'Vivid, thrilling, a delight ... Tim Flannery is a palaeontologist and ecologist of global standing, and this is a compelling and authoritative narrative of the evolution of Europe's flora and fauna, from the formation of the continent to its near future ... an exciting book, full of wonder' James McConnachie, Sunday Times A place of exceptional diversity, rapid change, and high energy, Europe has literally been at the crossroads of the world ever since the interaction of Asia, North America and Africa formed the tropical island archipelago that would become the continent of today. In this unprecedented evolutionary history, Tim Flannery shows how for the past 100 million years Europe has absorbed wave after wave of immigrant species; taking them in, transforming them, and sometimes hybridising them. Flannery reveals how, in addition to playing a vital role in the evolution of our own species, Europe was once the site of the formation of the first coral reefs, the home of some of the world's largest elephants, and now has more wolves than North America. This groundbreaking book charts the history of the land itself and the forces shaping life on it - including modern humans - to create a portrait of a continent that continues to exert a huge influence on the world today.

An Eocene (45 Ma) flora from Thunder Mountain caldera shows that montane conifer forest species from upper slopes descended to interfinger with mixed conifer-deciduous hardwood forest on the caldera floor then near 1700 m. Most species are allied to those in the western United States, but a few genera are in China. Precipitation was near 100 cm yearly, with most in summer.

Scientist believe that we would not be here if it were not for three great cataclysms in the early history of Earth and of the universe. This is the first book to explore the deep connection between the events that shaped life on Earth: the 'Big Bang' that spawned an entire universe; the explosion of a supernova, which seeded the solar system with heavy elements; and the crash of a comet or asteroid that caused the extinction of the dinosaurs and clear the way for the evolution of mammals.

Rain of Iron and Ice shows us the unmistakable evidence--from spaceprobe flybys of the planets to the scars on our own Earth--of cataclysmic comet and asteroid impacts. By comparing what we know about the earth's geology and paleontology with the ages of the other planets and moons in our solar system, Lewis makes the strongest case yet for sudden, dramatic extinctions and assesses the risks to planet Earth.

"Ever since the beginnings of paleontology in America, New Jersey has been 'the place' and William Gallagher--who terrorized his South Jersey mother by traipsing home with green mud, marl, and fossils--is the ideal guide to the wonderful dinosaurs and other fossils of the region. High school and college students, their teachers, interested general readers and professional paleontologists will all enjoy this book "-Earle E. Spamer, The Academy of Natural Sciences, Philadelphia "Citizens of New Jersey have needed this book for a long time . . . . William Gallagher shows all New Jerseyans why they can be proud of their state's role in dinosaur paleontology and in science as a whole."-David Parris, curator of natural history, New Jersey State Museum "A very enjoyable read--and an ambitious work that not only deals with dinosaurs of the New Jersey region, but much more besides. The hard-core dinosaur crowd will certainly want it, no matter where they live."-Louis Jacobs, author of Lone Star Dinosaurs and Quest for the African Dinosaurs "An impressive historical account of the search for dinosaur fossils in New Jersey . . . a fascinating account of prehistoric New Jersey when dinosaurs and other extinct creatures roamed its environs. It has great historical and scientific value."-Richard K. Olsson, professor of geological sciences, Rutgers University Did you know that Benjamin Franklin examined the first dinosaur bone in America from Woodbury, Gloucester County, in 1787--decades before the word dinosaur was even coined? Or that when the first reasonably complete dinosaur skeleton in the world was unearthed in Haddonfield, Camden County, in 1858, it was a major scientific breakthrough which forced paleontologists to completely revise their picture of dinosaur anatomy? Few people know that New Jersey is the nursery of American vertebrate paleontology When Dinosaurs Roamed New Jersey provides a succinct and readable history of the geology and paleontology of New Jersey from the time the region was covered by Cambrian seas 543 million years ago to the Pleistocene Ice Age only 10 to 15,000 years ago. William Gallagher tells the stories of professional and amateur fossil hunters, their discoveries, and their impact on the history of paleontological thought. He points out places in New Jersey and nearby where specimens characteristic of each era can be found. He shows how fossil evidence discovered in the state is helping paleontologists reconstruct the ecological interactions and behavior of dinosaurs, and discusses such continuing scientific controversies as the reason for the extinction of the dinosaurs. From tracking dinosaur footprints across the Newark basin, to digging for the last dinosaurs in the greensands of South Jersey, to finding a mushroom in ancient amber in East Brunswick, this book is the ideal introduction to the Garden State's fossils and prehistory. Dr. William B. Gallagher is the registrar of natural history at the New Jersey State Museum and a visiting lecturer in dinosaur paleontology at Rutgers University.

The first section of the book describes how zoo-archaeologists go about studying faunal remains from archaeological sites, and to explore the nature of these remains, and some of the information they provide. The second part discusses the relationship between humans and animals from earliest Africa to post-Medieval Britain. The latter can, of course, not be a complete survey; instead it sets out to describe some of the types of relationship that have existed throughout history, and the material consequences of those behaviours in the archaeological record. Helpful bibliography. One of the most lucid expositions on archaeozoology available' New Scientist.

George Poinar began collecting amber specimins over thirty years ago, but it was only recently that he, Roberta Poinar, and the rest of his research team astounded the scientific community with the news that they had obtained "live" DNA strands from an insect over 40 million years old. The news was so significant that it made headlines throughout the world. Since that time, their lab has remained extraordinarily active, and in the summer of 1993, they were able to announce the successful extraction of preserved DNA strands over 125 million years old. Thus, there is now DNA available for study dating from the early dinosaur period.In passages that read more like an Indiana Jones screenplay than a story about scientific research, the Poinars describe how what began as a hobby grew into a semi-obsession which ultimately led to a breakthrough scientific discovery. Along the way, they encounter all manner of unusual characters, from threatening black marketeers and gun-toting guerrillas to extraordinarily talented scientists, and of course, the luminously beautiful specimins captured in the still-life of amber.

How can the tracks of dinosaurs best be interpreted and used to reconstruct them? In many Mesozoic sedimentary rock formations, fossilized footprints of bipedal, three-toed (tridactyl) dinosaurs are preserved in huge numbers, often with few or no skeletons. Such tracks sometimes provide the only clues to the former presence of dinosaurs, but their interpretation can be challenging: How different in size and shape can footprints be and yet have been made by the same kind of dinosaur? How similar can they be and yet have been made by different kinds of dinosaurs? To what extent can tridactyl dinosaur footprints serve as proxies for the biodiversity of their makers? Profusely illustrated and meticulously researched, Noah's Ravens quantitatively explores a variety of approaches to interpreting the tracks, carefully examining within-species and across-species variability in foot and footprint shape in nonavian dinosaurs and their close living relatives. The results help decipher one of the world's most important assemblages of fossil dinosaur tracks, found in sedimentary rocks deposited in ancient rift valleys of eastern North America. Those often beautifully preserved tracks were among the first studied by paleontologists, and they were initially interpreted as having been made by big birds-one of which was jokingly identified as Noah's legendary raven.

The partial skeleton of Homo erectus found in Kenya by Alan Walker, Richard Leakey, and others is truly one of the great discoveries in paleoanthropology, after the world's best paleoanthropologists have diligently searched for traces of Homo erectus in Africa and Asia for a century. In this book, the authors present descriptions and photographs of all parts of the skeleton and accompany these with a thorough analysis. It consists of three parts. The first part covers the geology, dating, paleoenvironments, and the taphonomy of the site. The second part is a description of the specimen and a review of other Homo erectus specimens from the Lake Turkana region. The last part is composed of analytical papers on certain aspects of the boy's biology as they apply to other Homo erectus specimens. "What impresses me most about the volume is that apart from the basic description of the fossil, which itself is of great importance, the editors have sought out leading experts to tackle problems relating to specific issues in the evolutionary biology of Homo erectus. Many of these chapters would stand alone as major contributions. Together, they make a remarkable volume that will become a standard reference." (Robert A. Foley, Professor of Biological Anthropology, University of Cambridge)

Picture a world of dog-sized scorpions and millipedes as long as a car; tropical rainforests with trees towering over 150 feet into the sky and a giant polar continent five times larger than Antarctica. That world was not imaginary; it was the earth more than 300 million years ago in the Carboniferous period of the Paleozoic era. In Carboniferous Giants and Mass Extinction, George R. McGhee Jr. explores that ancient world, explaining its origins; its downfall in the end-Permian mass extinction, the greatest biodiversity crisis to occur since the evolution of animal life on Earth; and how its legacies still affect us today. McGhee investigates the consequences of the Late Paleozoic ice age in this comprehensive portrait of the effects of ancient climate change on global ecology. Carboniferous Giants and Mass Extinction examines the climatic conditions that allowed for the evolution of gigantic animals and the formation of the largest tropical rainforests ever to exist, which in time turned into the coal that made the industrial revolution possible-and fuels the engine of contemporary anthropogenic climate change. Exploring the strange and fascinating flora and fauna of the Late Paleozoic ice age world, McGhee focuses his analysis on the forces that brought this world to an abrupt and violent end. Synthesizing decades of research and new discoveries, this comprehensive book provides a wealth of insights into past and present extinction events and climate change.

Introduction by Stephen Jay Gould

In the geological record, there are five major mass extinctions—the "Big Five." The most famous happened at the end of the Cretaceous Period, when the dinosaurs and two-thirds of all marine animal species were wiped out, opening the door for the age of mammals and the rise of Homo Sapiens. Using this example as a springboard, David M. Raup leaps into an egaging discussion of the theories, assumptions, and difficulties associated with the science of species extinction. Woven is along the way are stories of the trilobite eye, tropical reefs, flying reptiles, and the fate of the heath hen on Martha's Vineyard, a very modern extinction.

This is the first major book to present a comprehensive overview of the current state of extinction studies. At the end of the journey, Raup has put forward the best science of the day to answer the question posed by the title: Bad genes or bad luck?

"An eminently entertaining and informative read." —Malcolm W. Browne, New York Times Book Review

"A delightful little book about life on this planet and about extinctions, in particular. It is as much about the philosophy and methodology of science as about the downside of evolution." —Clark R. Chapman, Planetary Science Institute

"David Raup's Extinction will change the way many of us perceive our world. In a style that is both elegant and persuasive, Raup undercuts the popular and comfortable notions that extinction is a mark of failure. . . . We are shown a world that is less certain, but in many ways more interesting than the one we imagined we occupied." —Roger Lewin, author of Bones of Contention

A spectacular collectible volume, with masterful photographs and expert commentary on some of the world's most striking fossils About four hundred million years ago earthquake activity and possibly major storms caused sudden movements of large quantities of muddy sediment along the seafloor. Animal communities in the path of these sediment-laden flows were instantly engulfed, the inhabitants "frozen" in the last moment of their lives. Amazingly, many of the creatures lost in this ancient catastrophe were almost perfectly preserved through the eons, fossilized in a thick series of muds now known as the Hunsruck Slate west of the Rhine Valley in western Germany. Excavations there have yielded the most diverse and surpassingly beautiful collection of marine fossils of the Devonian period ever discovered. This book pays tribute to the exquisite fossils of the Hunsruck Slate. Large full-color photographic plates display fossil sponges, brachiopods, clams, starfish, sea lilies, trilobites, worms, sea spiders, sea stars, crustaceans, corals, and many other species. An accessible commentary recounts the discovery of the fossils and explains how the slate was formed, how the animals are preserved, the significance of the fossils, and the controversies that surround them. A special presentation in every way, this book makes an exceptional contribution to the fascinating history of life on Earth.

Illustrated Key to Skulls of Genera of North American Land Mammals is a manual that contains illustrations of North American land mammals such as marsupials, shrews, bats, moles among many others. This manual is a well-illustrated key, useful for identifying mammals through cranial characteristics. It also contains line-drawings, and many photographs to aid in identifying related genera. The distribution, diversity, and characteristics of each order and family of land mammals found in North American and to the north of Mexico are briefly discussed. J. Knox Jones, Jr., has been a practicing mammalogist for more than 40 years. Currently he is a Paul Whitfield Horn Professor of Biological Sciences at Texas Tech and a Curator in the Museum there. Jones has authored or edited 14 books among is more than 350 publications, and has studied mammals on five continents. He is a past president of the American Society of Mammalogists and has been awarded the C. Hart Merriam Award, the H. H. T. Jackson Award, and Honorary Membership by that society. In 1992, he was selected as Texas Distinguished Scientist of the Year by the Texas Academy of Science, and was awarded the Donald W. Tinkle Research Excellence Award by the Southwestern Association of Naturalists. Richard W. Manning is a member of the faculty of Southwest Texas State University in San Marcos. He has authored more than 40 publications, most of which deal with mammals. Manning has had considerable instructional experience in laboratories in mammalogy, and has been cited for his excellence in teaching. He is also an avid field biologist, and thus has studied mammals in their natural habitats as well. Manning took most of the photographs used in this laboratory manual and made many of the line drawings.
