From The Land Before Time to Jurassic Park, images of fantastically large, long-necked, plant-eating dinosaurs have captured our imaginations. These are the sauropods: centerpieces of museums and gentle giants of the distant past. Imagine what it must have been like to crest a hill and see in the valley below not just one sauropod, but an entire herd, feeding its way across the landscape. The most massive land animals ever to have lived, sauropods roamed widely across the continents through most of the "Age of Dinosaurs" from about 220 to 65 million years ago. They reached incredible sizes, giving rise to the question: Why were they so big? Early guesses suggested that they gained protection from predators by virtue of their size, which also allowed them to reach the tops of trees in order to eat leaves and conifer needles. More recent hypotheses hold that they needed a long and complicated digestive tract due to their consumption of low-nutrient food sources: size was an offshoot of that need. Whatever the explanation, there is little doubt that natural selection produced something extraordinary when the Sauropoda diversified into a wide variety of species.This book combines majestic artwork and the best of paleontological research to resurrect the lives of sauropods. The Sauropod Dinosaurs shows how these amazing creatures raised and defended their young, traveled in groups, and interacted with the rich diversity of Mesozoic plants and animals. Beautiful enough to sit on the coffee table, the book also serves as the best reference available on these bygone giants. Anyone with a passion for dinosaurs or prehistoric life will cherish this once-in-a-generation masterpiece. The book includes the following features:* Over 200 full-color illustrations* More than 100 color photographs from museums, field sites, and collections around the world* Thoughtfully placed drawings and charts* Clearly written text reviewed by major sauropod researchers* Descriptions of the latest sauropod concepts and discoveries* A field guide to major groups of sauropods* Detailed skeletal reconstructions and anatomical restorations* A comprehensive glossary

The neurologic subspecialty of Movement Disorders is complicated with many different entities, making the differential diagnosis difficult. One of the most important aspects of these different entities is their visual appearance. Still photographs do not give sufficient information, but videos like the ones included in this volume can provide dimension, context, and critical information. The variety of visual appearances is wide and seeing many videos is necessary to develop skill in making a diagnosis. Involuntary movements are even more complicated and the adage "seeing is believing" has never been more true. Despite this, few books include videos portraying involuntary movements.Involuntary Movements: Classification and Video Atlas pairs descriptions of the clinical features of various involuntary movements with video depictions of the involuntary movements in action. In a unique approach, this book considers two aspects of the diagnosis of involuntary movements: the phenomenology - as depicted in approximately 200 video supplements - and the etiology. The book also discusses the current consensus on the classification, pathophysiology, and treatment of each involuntary movement.

The second edition of The Neurologic Examination looks at how to conduct a clinical neurological examination through a pathophysiological approach to the nervous system. This new edition is brought up to date with new data on genetic and immunological disorders and a significant expansion of illustrations of skin manifestations of neurologic disorders. The book provides in-depth instructions for clinicians with a logical order of history and the different parts of the examination. Organized by the functional anatomy of the nervous system, the book provides a bridge from basic science to symptoms and signs of many common and rare neurologic disorders, which will help in making diagnoses. The authors look at how to carry out an examination in different circumstances, from outpatients to patients in respiratory distress, with stroke and epilepsy, and various states of consciousness including coma. Laboratory testing is recommended when appropriate, but the main emphasis is on history and physical examination. The book contains over a hundred discussion boxes with details about neurologic disorders and history. While mainly directed to students and residents learning how to do a neurologic examination, it will still be useful even for more experienced clinicians.

This is the first book to offer a comprehensive overview of higher-order motor disorders. It introduces new concepts emerging from basic neurosciences and shows how they have impacted on the field of cognitive motor control and led to new vistas for the understanding of Higher-order Motor Disorders far beyond the traditional field of topological diagnosis. It describes in detail a wide range of clinical disorders including those of bimanual co-ordination, apraxia and sensorimotor transformation deficits, motor neglect, anarchic hand syndrome, imitation and utilisation behaviours, action motivational and action monitoring disorders, as well as new approaches to motor cortex plasticity and reorganisation and rehabilitation of complex movement problems. The book reviews the topic, starting with a description of the neuroanatomical, neurobiological and cognitive basis of normal motor behaviours, before moving on to cover the clinical features of the disordered states. The final chapters cover the issues of plasticity and recovery, pharmacological treatments and rehabilitation.This volume will stimulate research and foster new insights into cognitive and motivational motor disorders. With expert contributions from the major international centres in Europe and the Americas his book gives a truly new framework for a complex and confusing field.

This scientific detective story is the first book which explains clearly the science used by paleontologists, and the new, cutting-edge techniques that led to the discovery of Seismosaurus, the longest dinosaur yet known--and possibly the largest land animal to have ever lived. 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 did it die? Part catalogue of the workings of paleontological science in the 1990s, the book also illustrates the exciting collaboration between Gillette, the chemists and physicists who helped to reconstruct Seismosaurus.

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.

The first extended study of Frank Auerbach's remarkable portrait drawings reveals their complexity and ambition as works of graphic artThis book offers an original approach to one of Britain’s leading artists: Frank Auerbach (b. 1931). It looks in detail at his portrait drawings, which Auerbach has been making since the 1950s, and which he has always considered important, freestanding works of art. By turns eerie, shocking, enigmatic, and hauntingly tender, they demand fresh interpretation and investigation. Reproducing more than 130 examples of these portraits, some for the first time, and featuring new essays by curators, scholars, and critics, this book provides an unprecedented opportunity to explore and reassess these striking and sometimes unsettling works of graphic art. Frank Auerbach: Drawings of People includes texts by both the editors and the artist himself, and new essays by Kate Aspinall, James Finch, Alex Massouras, David Mellor, and Barnaby Wright.  Distributed for the Paul Mellon Centre for Studies in British Art
