But it didn't stop him from exploring the American West. Here Wallace Stegner, a Pulitzer Prize-winner, gives us a thrilling account of Powell's struggle against western geography and Washington politics. We witness the successes and frustrations of Powell's distinguished career, and appreciate his unparalleled understanding of the West.<

    Wallace, a contemporary of Charles Darwin, spent nearly a decade cataloging the plant and animal species which inhabited the unique geographical area of the Malay Archipelago, and remains to this day one of the most extensive works of natural history ever written.

    However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this readable and wide-ranging book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are living fossils? What fossils will we leave behind for future generations to examine? Beyond the scientific aspects, Thomson highlights the impact of fossils on philosophy and mythology, our concept of time, and today's popular culture. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination.

    The ultimate reference to 355 dinosaurs from the Triassic, Jurassic and Cretaceous periods, including more than 900 watercolors, maps, timelines and photographs.Includes the best-known non-dinosaurs such as sea-living placodonts, nothosaurs, plesiosaurs, mosasaurs and ichthyosaurs, as well as the airborne pterosaurs.With informative descriptions, technically accurate profiles, anatomical illustrations, depictions of dinosaur habitats, and maps of fossil sites.

    Through dramatic graphics and age-appropriate text, this authoritative volume charts the discovery of all the main types of dinosaurs and reveals the latest details on how these creatures most likely looked, behaved, defended themselves, found food, cared for their young, and interacted. Stunning murals, based on scientific evidence, depict various dinosaurs in their habitats--beautifully complementing the color photographs, paintings, charts, and maps. Some 53 major types of dinosaurs are described, representing a wide range of physical structures, sizes, and lifestyles.The book presents recent discoveries and current scientific thought--including the dinosaur-bird connection, profiles of feathered dinosaurs, and theories on dinosaur extinction. Readers also see how today' s paleontologists obtain evidence, piece together clues, and continue to reconstruct life in prehistoric times.

    Full of striking, singular art, this collection also contains infographics about relevant topics such as lab equipment, rates of women currently working in STEM fields, and an illustrated scientific glossary. The women profiled include well-known figures like primatologist Jane Goodall, as well as lesser-known pioneers such as Katherine Johnson, the African-American physicist and mathematician who calculated the trajectory of the 1969 Apollo 11 mission to the moon.

    Making big ideas simple, Dean takes readers on a journey to uncover what makes a dinosaur a dinosaur, what dinosaurs ate, how they evolved, what caused them to go extinct, and more!Perfect for anyone fascinated by the dinosaur exhibits at museums, palaeontology and fans of Jurassic Park.

    He places us on the outcrops, rock hammer in hand, to examine the evidence for how these rough-hewn lands came to be. We see California and its gold assembled from pieces of old ocean floor and the relentless movements of the Earth’s tectonic plates. We witness the birth of the Rockies. And we investigate the violent earthquakes that continue to shape the region today. Into the West’s geologic story, Meldahl also weaves its human history. As we follow the adventures of John C. Frémont, Mark Twain, the Donner party, and other historic characters, we learn how geologic forces have shaped human experience in the past and how they direct the fate of the West today.

    In Café Neandertal, Bahrami follows this compelling riddle along a path populated with colorful local personalities and opinionated, polemical, and brilliant archaeologists working in remote and fascinating places across Eurasia, all the while maintaining a firm foothold in the Dordogne, a region celebrated by the local tourist office as a vacation destination for 400,000 years. From this prehistoric perch Bahrami gets to know first-hand the Neandertals and the people who love them — those who have devoted their lives to them. She is thrown into a world debating not only what happened to these close cousins but also what legacy they have left for those who followed.Café Neandertal is also a detective story, investigating one of the biggest mysteries of prehistory and archaeology: Who were the Neandertals? Why did they disappear around 35,000 years ago? And more mysteriously, what light do they shed on us moderns?Bahrami takes readers into the thick of an excavation, neck-deep in Neanderthal dirt, and to the front row of the heated debates about our long-lost cousins. Café Neandertal pulls us deeply into the complex mystery of the Neandertals, shedding a surprising light on what it means to be human.

    The prolonged encounter between the Cro-Magnons and the archaic Neanderthals and between 45,000 and 30,000 years ago was one of the defining moments of history. The Neanderthals survived for some 15,000 years in the face of the newcomers, but were finally pushed aside by the Cro-Magnons' vastly superior intellectual abilities and cutting-edge technologies, which allowed them to thrive in the intensely challenging climate of the Ice Age.What do we know about this remarkable takeover? Who were the first modern Europeans and what were they like? How did they manage to thrive in such an extreme environment? And what legacy did they leave behind them after the cold millennia? The age of the Cro-Magnons lasted some 30,000 years?longer than all of recorded history. Cro-Magnon is the story of a little known, yet seminal, chapter of human experience.

    On May 24, 1869 a one-armed Civil War veteran, John Wesley Powell and a ragtag band of nine mountain men embarked on the last great quest in the American West. The Grand Canyon, not explored before, was as mysterious as Atlantis—and as perilous. The ten men set out from Green River Station, Wyoming Territory down the Colorado in four wooden rowboats. Ninety-nine days later, six half-starved wretches came ashore near Callville, Arizona.Lewis and Clark opened the West in 1803, six decades later Powell and his scruffy band aimed to resolve the West’s last mystery. A brilliant narrative, a thrilling journey, a cast of memorable heroes—all these mark Down the Great Unknown, the true story of the last epic adventure on American soil.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    Bursting with all the suspense and intrigue of a fast paced adventure novel, here is Johanson’s lively account of the extraordinary discovery of “Lucy.” By expounding the controversial change Lucy makes in our view of human origins, Johanson provides a vivid, behind-the-scenes account of the history of pealeoanthropology and the colorful, eccentric characters who were and are a part of it. Never before have the mystery and intricacy of our origins been so clearly and compellingly explained as in this astonighing and dramatic book.

    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.
