Description : Characterized by a surge in biodiversity and evolutionary development, the Paleozoic Era ushered in the beginnings of life as we know it. Within these pages, readers will discover the fossil and geologic evidence from this time that reveals a dynamic planet, where new species of plants and animals were constantly emerging and continents were breaking apart and reforming. While many of the species from this era are now extinct and the continents are relatively stable, remnants of this era still continue to shed much-needed light on the conditions of Earth, both past and present.

Description : This volume presents a set of research papers that provide new data and interpretations of the Permian–Triassic terranes of SE Gondwana, now exposed in South Island, New Zealand. Following an introduction for general readers, a historical summary and a review of biostratigraphy, the individual papers primarily focus on the Permian magmatic arc of the Brook Street Terrane, the classic Permian Dun Mountain ophiolite and the Permian–Triassic Maitai Group sedimentary succession. The new results emphasize the role of subduction and terrane displacement adjacent to the Permo-Triassic Gondwana margin, and present fundamental insights into three crustal processes: subduction initiation, supra-subduction zone oceanic crust genesis and forearc basin evolution. The volume concludes with a wide-ranging summary and synthesis of the regional Cambrian to Early Cretaceous tectonostratigraphy of New Zealand’s South Island in relation to the wider areas of Zealandia, East Australia and West Antarctica. The volume will interest geoscientists, including stratigraphers, sedimentologists, palaeontologists, igneous petrologists, geochemists, geochronologists and economic geologists, and is aimed at professional geologists and advanced students of geology.

Description : An investigation into a 250-million-year-old environmental apocalypse that predated the age of the dinosaurs describes an event that caused the annihilation of ninety percent of all plant and animal species on Earth, taking a close up look at the prehistoric world of the gorgons, the causes of mass extinctions, and their implications for the future of humankind.

Description : The present book combines three main aspects: five major mass extinctions; contributions on some other minor extinctions; and more importantly contributions on the current mass extinction. All three aspects are introduced through interesting studies of mass extinctions in diverse organisms ranging from small invertebrates to mammals and take account of the most accepted subjects discussing mass extinctions in insects, mammals, fishes, ostracods and molluscs.

Description : One of the leading textbooks in its field, Bringing Fossils to Life applies paleobiological principles to the fossil record while detailing the evolutionary history of major plant and animal phyla. It incorporates current research from biology, ecology, and population genetics, bridging the gap between purely theoretical paleobiological textbooks and those that describe only invertebrate paleobiology and that emphasize cataloguing live organisms instead of dead objects. For this third edition Donald R. Prothero has revised the art and research throughout, expanding the coverage of invertebrates and adding a discussion of new methodologies and a chapter on the origin and early evolution of life.

Description : The invasion of land by ocean-dwelling plants and animals was one of the most revolutionary events in the evolution of life on Earth, yet the animal invasion almost failed—twice—because of the twin mass extinctions of the Late Devonian Epoch. Some 359 to 375 million years ago, these catastrophic events dealt our ancestors a blow that almost drove them back into the sea. If those extinctions had been just a bit more severe, spiders and insects—instead of vertebrates—might have become the ecologically dominant forms of animal life on land. This book examines the profound evolutionary consequences of the Late Devonian extinctions and the various theories proposed to explain their occurrence. Only one group of four-limbed vertebrates exists on Earth, while other tetrapod-like fishes are extinct. This gap is why the idea of "fish with feet" seems so peculiar to us, yet such animals were once a vital part of our world, and if the Devonian extinctions had not happened, members of these species, like the famous Acanthostega and Ichthyostega, might have continued to live in our rivers and lakes. Synthesizing decades of research and including a wealth of new discoveries, this accessible, comprehensive text explores the causes of the Devonian extinctions, the reasons vertebrates were so severely affected, and the potential evolution of the modern world if the extinctions had never taken place.

Description : From where—and what—does water come? How did it become the key to life in the universe? Water from Heaven presents a state-of-the-art portrait of the science of water, recounting how the oxygen needed to form H2O originated in the nuclear reactions in the interiors of stars, asking whether microcomets may be replenishing our world's oceans, and explaining how the Moon and planets set ice-age rhythms by way of slight variations in Earth's orbit and rotation. The book then takes the measure of water today in all its states, solid and gaseous as well as liquid. How do the famous El Niño and La Niña events in the Pacific affect our weather? What clues can water provide scientists in search of evidence of climate changes of the past, and how does it complicate their predictions of future global warming? Finally, Water from Heaven deals with the role of water in the rise and fall of civilizations. As nations grapple over watershed rights and pollution controls, water is poised to supplant oil as the most contested natural resource of the new century. The vast majority of water "used" today is devoted to large-scale agriculture and though water is a renewable resource, it is not an infinite one. Already many parts of the world are running up against the limits of what is readily available. Water from Heaven is, in short, the full story of water and all its remarkable properties. It spans from water's beginnings during the formation of stars, all the way through the origin of the solar system, the evolution of life on Earth, the rise of civilization, and what will happen in the future. Dealing with the physical, chemical, biological, and political importance of water, this book transforms our understanding of our most precious, and abused, resource. Robert Kandel shows that water presents us with a series of crucial questions and pivotal choices that will change the way you look at your next glass of water.
