These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone.What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses.Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.

    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.

    Learning all the tongue twisting names, picking favorites based on ferocity, armor, or sheer size. For many kids this love of ‘terrible lizards’ fizzles out at some point between starting and leaving primary school. All those fancy names slowly forgotten, no longer any need for a favorite.For all those child dino fanatics who didn’t grow up to become paleontologists, dinosaurs seem like something out of mythology. They are dragons, pictures in books, abstract, other, extinct.They are at the same time familiar and mysterious. And yet we’re in an age of rapid discovery—new dinosaur species and genera are being discovered at an accelerating rate, we’re learning more about what they looked like, how they lived, how they evolved and where they all went.This series isn’t just a top trumps list of dino facts—we’re interested in the why and the how and like all areas of science there is plenty of controversy and debate.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

    With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the twenty-first century reader.

    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.

    The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.

    Explains how fossils are formed and what they tell us about the past.

    Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the "monkey business of creationism," Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of "missing links" that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process.Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as a leading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.

    Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human.From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.

    In Otherlands, Halliday makes sixteen fossil sites burst to life on the page.This book is an exploration of the Earth as it used to exist, the changes that have occurred during its history, and the ways that life has found to adapt―or not. It takes us from the savannahs of Pliocene Kenya to watch a python chase a group of australopithecines into an acacia tree; to a cliff overlooking the salt pans of the empty basin of what will be the Mediterranean Sea just as water from the Miocene Atlantic Ocean spills in; into the tropical forests of Eocene Antarctica; and under the shallow pools of Ediacaran Australia, where we glimpse the first microbial life.Otherlands also offers us a vast perspective on the current state of the planet. The thought that something as vast as the Great Barrier Reef, for example, with all its vibrant diversity, might one day soon be gone sounds improbable. But the fossil record shows us that this sort of wholesale change is not only possible but has repeatedly happened throughout Earth history.Even as he operates on this broad canvas, Halliday brings us up close to the intricate relationships that defined these lost worlds. In novelistic prose that belies the breadth of his research, he illustrates how ecosystems are formed; how species die out and are replaced; and how species migrate, adapt, and collaborate. It is a breathtaking achievement: a surprisingly emotional narrative about the persistence of life, the fragility of seemingly permanent ecosystems, and the scope of deep time, all of which have something to tell us about our current crisis.

    The story starts in earnest 3.8 billion years ago, with the earliest-known form of life on Earth, a bacteria that still exists today, and journeys through action-packed millennia, charting the appearance of new life forms as well as devastating extinction events. Of course, the ever-popular and endlessly intriguing dinosaurs feature large, but Prehistoric Life gives you the whole picture, and the plants, invertebrates, amphibians, birds, reptiles, and mammals that are the ancestors of today's species also populate its pages, making this book unprecedented in its coverage of prehistory. Specially commissioned artworks use cutting-edge technology to render species in breathtakingly realistic fashion, with astonishing images of prehistoric remains, such as skeletons and fossils, to complete the story. To put all the evidence in context, the concept of geological time is explored, as is the classification of species and how the evidence for their evolution is preserved and can be deciphered.New technologies have brought new life to inanimate fossils. CT scanning, for example, unlocks a 3D image of a plant or animal from a piece of rock, which can then be viewed from all angles revealing never-before-seen details. From this researchers can fill in missing pieces and even simulate how an animal might have moved. Panels explore these and numerous other scientific techniques for recovering, dating, and reconstructing, as well as profiling individuals, key excavations and discoveries, and some of the unique anatomical features that nature has developed over the course of time.The last section of the book looks at the development of humans and the eventual rise to dominance of Homo sapiens, exploring not only their changing anatomy as revealed by the fossils but also the evidence for culture and society as evidenced by extraordinary cave paintings and intricately worked tools.In combination, the stunning visuals, captivating, authoritative text, and comprehensive approach make Prehistoric Life a fascinating and revealing encyclopedia that will appeal to the whole family.TABLE OF CONTENTS1.

    Now, The Lost Spells, a book kindred in spirit and tone, continues to re-wild the lives of children and adults.The Lost Spells evokes the wonder of everyday nature, conjuring up red foxes, birch trees, jackdaws, and more in poems and illustrations that flow between the pages and into readers’ minds. Robert Macfarlane’s spell-poems and Jackie Morris’s watercolour illustrations are musical and magical: these are summoning spells, words of recollection, charms of protection. To read The Lost Spells is to see anew the natural world within our grasp and to be reminded of what happens when we allow it to slip away.
