    These flying reptiles, which include the pterodactyls, shared the world with the nonavian dinosaurs until their extinction 65 million years ago. Some pterosaurs, such as the giant azhdarchids, were the largest flying animals of all time, with wingspans exceeding thirty feet and standing heights comparable to modern giraffes. This richly illustrated book takes an unprecedented look at these astonishing creatures, presenting the latest findings on their anatomy, ecology, and extinction.Pterosaurs features some 200 stunning illustrations, including original paintings by Mark Witton and photos of rarely seen fossils. After decades of mystery, paleontologists have finally begun to understand how pterosaurs are related to other reptiles, how they functioned as living animals, and, despite dwarfing all other flying animals, how they managed to become airborne. Here you can explore the fossil evidence of pterosaur behavior and ecology, learn about the skeletal and soft-tissue anatomy of pterosaurs, and consider the newest theories about their cryptic origins. This one-of-a-kind book covers the discovery history, paleobiogeography, anatomy, and behaviors of more than 130 species of pterosaur, and also discusses their demise at the end of the Mesozoic.The most comprehensive book on pterosaurs ever publishedFeatures some 200 illustrations, including original paintings by the authorCovers every known species and major group of pterosaursDescribes pterosaur anatomy, ecology, behaviors, diversity, and moreEncourages further study with 500 references to primary pterosaur literature

    To love and loathe the fox is a British condition."The fox is our apex predator, our most beautiful and clever killer. We have witnessed its wild touch, watched it slink by bins at night and been chilled by its high-pitched scream. And yet we long to stroke the tumbling cubs outside their tunnel homes and watch the vixen stalk the cornfield.There is something about foxes. They captivate us like no other species.Exploring a long and sometimes complicated relationship, The Wild Life of the Fox captures our love – and sometimes loathing – of this magnificent creature in vivid detail and lyrical prose.

    Drawing on new translations of Mutis's nearly forgotten writings, this fascinating story of scientific adventure in eighteenth-century South America retrieves Mutis's contributions from obscurity.In 1760, the 28-year-old Mutis—newly appointed as the personal physician of the Viceroy of the New Kingdom of Granada—embarked on a 48-year exploration of the natural world of northern South America. His thirst for knowledge led Mutis to study the region's flora, become a professor of mathematics, construct the first astronomical observatory in the Western Hemisphere, and amass one of the largest scientific libraries in the world. He translated Newton's writings and penned essays about Copernicus; lectured extensively on astronomy, geography, and meteorology; and eventually became a priest. But, as two-time Pulitzer Prize–winner Edward O. Wilson and Spanish natural history scholar José M. Gómez Durán reveal in this enjoyable and illustrative account, one of Mutis's most magnificent accomplishments involved ants.Acting at the urging of Carl Linnaeus—the father of taxonomy—shortly after he arrived in the New Kingdom of Granada, Mutis began studying the ants that swarmed everywhere. Though he lacked any entomological training, Mutis built his own classification for the species he found and named at a time when New World entomology was largely nonexistent. His unorthodox catalog of army ants, leafcutters, and other six-legged creatures found along the banks of the Magdalena provided a starting point for future study.Wilson and Durán weave a compelling, fast-paced story of ants on the march and the eighteenth-century scientist who followed them. A unique glance into the early world of science exploration, Kingdom of Ants is a delight to read and filled with intriguing information.

    This edition is designed to attain a thorough understanding of this vital branch of chemistry.

    Notable is the inclusion, for the first time, of four-colour photographs and illustrations throughout. Like previous editions, the book shows how evolutionary biologists analyze all aspects of behaviour.

    Cave paintings of the giant beasts hint at the profound role they played in early human culture-our Ice Age ancestors built igloo-shaped huts out of mammoth bones and even feasted on mammoth tongues. Eager to uncover more clues to this mystical prehistoric age, explorers since the time of Peter the Great have scoured Siberia for mammoth remains. Now a new generation of explorers has taken to the tundra. Armed with GPS, ground-penetrating radar, and Soviet-era military helicopters, they seek an elusive prize: a mammoth carcass that will help determine how the creature lived, how it died-and how it might be brought back to life.In this adventure-filled narrative, science writer Richard Stone follows two teams of explorers-one Russian/Japanese, the other a French-led consortium-as they battle bitter cold, high winds, supply shortages, and the deeply rooted superstitions of indigenous peoples who fear the consequences of awakening the "rat beneath the ice." Stone travels from St. Petersburg to the Arctic Circle, from the North Sea to high-tech Japanese laboratories, as he traces the sometimes-surreal quest of these intrepid scientists, whose work could well rewrite our planet's evolutionary history. A riveting tale of high-stakes adventure and scientific hubris, Mammoth is also an intellectual voyage through uncharted moral terrain, as we confront the promise and peril of resurrecting creatures from the deep past.

This guide includes more than 870 stunning color photographs, starting with a general impression of the species and progressing to more detailed images of the bird throughout its life cycle. Quiz questions in the captions will engage and challenge all birders and help them benefit from this simplified, commonsense approach to identification.

    With plenty of engaging material, practice questions, and practical ideas, this updated edition contains everything your students need to succeed in Cambridge IGCSE biology.

    Countless behaviors separate us from the rest of the animal kingdom, but all of them can be traced one way or another to six traits that are unique to the human race—our big toe, our opposable thumb, our oddly shaped pharynx, and our ability to laugh, kiss, and cry. At first glance these may not seem to be connected but they are. Each marks a fork in the evolutionary road where we went one way and the rest of the animal kingdom went another. Each opens small passageways on the peculiar geography of the human heart and mind.Walter weaves together fascinating insights from complexity theory, the latest brain scanning techniques, anthropology, artificial intelligence, cognitive psychology, and robotics to explore how the smallest of changes over the past six million years – all shaped by the forces of evolution -- have enabled a primate once on the brink of extinction to evolve into a creature that would one day create all of the grand and exuberant edifices of human culture.As the story of each trait unfolds, Walter explains why our brains grew so large and complex, why we find one another sexually attractive, how toolmaking laid the mental groundwork for language, why we care about what others think, and how we became the creature that laughs and cries and falls in love. Thumbs, Toes and Tears is original, informative, and delightfully thought-provoking.
