This chance encounter in the basement of the Natural History Museum of Los Angeles County sparked Troll’s obsession with Helicoprion, a mysterious monster from deep time.In 2010, tattooed undergraduate student and returning Iraq War veteran Jesse Pruitt became seriously smitten with a Helicoprion fossil in a museum basement in Idaho. These two bizarre-shark disciples found each other, and an unconventional band of collaborators grew serendipitously around them, determined to solve the puzzle of the mysterious tooth whorl once and for all.Helicoprion was a Paleozoic chondrichthyan about the size of a modern great white shark, with a circular saw of teeth centered in its lower jaw—a feature unseen in the shark world before or since. For some ten million years, long before the Age of Dinosaurs, Helicoprion patrolled the shallow seas around the supercontinent Pangaea as the apex predator of its time.Just a few tumultuous years after Pruitt and Troll met, imagination, passion, scientific process, and state-of-the-art technology merged into an unstoppable force that reanimated the remarkable creature—and made important new discoveries.In this groundbreaking book, Susan Ewing reveals these revolutionary insights into what Helicoprion looked like and how the tooth whorl functioned—pushing this dazzling and awe-inspiring beast into the spotlight of modern science.

    The trilobites, which dominated the ocean floors for 300 million years, are gone. The last of the dinosaurs was wiped out by a Mount Everest-sized meteorite that slammed into the earth 65 million years ago. The great flying reptiles are gone, and so are the marine reptiles, some of them larger than a humpback whale. Before humans crossed the Bering land bridge some 15,000 years ago, North America was populated by mastodons, mammoths, saber-toothed tigers, and cave bears. They too are MIA. Passenger pigeons once flew over North America in flocks that numbered in the billions; the last one died in 1914.In this book you will meet creatures that were driven to extinction even more recently, as well as some that were brought back from the brink. You will even encounter animals not known to exist until recently -- an antidote to extinction.

    First published in 1970, the book seeks to explain the causes for the 13 May 1969 riots in Kuala Lumpur.Dr Mahathir sets out his view as to why the Malays are economically backward and why they feel they must insist upon immigrants becoming real Malaysians speaking in due course nothing but Malay, as do immigrants to America or Australia speak nothing but the language of what the author calls “the definitive people”. He argues that the Malays are the rightful owners of Malaya. He also argues that immigrants are guests until properly absorbed, and that they are not properly absorbed until they have abandoned the language and culture of their past.

    He had a talent for drawing and an interest in birds, and he would spend the next thirty-five years traveling to the remotest regions of his new country–often alone and on foot–to render his avian subjects on paper. The works of art he created gave the world its idea of America. They gave America its idea of itself. Here Richard Rhodes vividly depicts Audubon’s life and career: his epic wanderings; his quest to portray birds in a lifelike way; his long, anguished separations from his adored wife; his ambivalent witness to the vanishing of the wilderness. John James Audubon: The Making of an American is a magnificent achievement.

    The awesome journey of life's transformation from the first microbes 4 billion years ago to Homo sapiens today is an epic that we are only now beginning to grasp. Magnificent and bizarre, it is the story of how we got here, what we left behind, and what we brought with us. We all know about evolution, but it still seems absurd that our ancestors were fish. Darwin's idea of natural selection was the key to solving generation-to-generation evolution -- microevolution -- but it could only point us toward a complete explanation, still to come, of the engines of macroevolution, the transformation of body shapes across millions of years. Now, drawing on the latest fossil discoveries and breakthrough scientific analysis, Carl Zimmer reveals how macroevolution works. Escorting us along the trail of discovery up to the current dramatic research in paleontology, ecology, genetics, and embryology, Zimmer shows how scientists today are unveiling the secrets of life that biologists struggled with two centuries ago. In this book, you will find a dazzling, brash literary talent and a rigorous scientific sensibility gracefully brought together. Carl Zimmer provides a comprehensive, lucid, and authoritative answer to the mystery of how nature actually made itself.

    Lavishly illustrated with over sixty original artworks, All Yesterdays aims to challenge our notions of how prehistoric animals looked and behaved. As a critical exploration of palaeontological art, All Yesterdays asks questions about what is probable, what is possible, and what is commonly ignored.Written by palaeozoologist Darren Naish, and palaeontological artists John Conway and C.M. Kosemen, All Yesterdays is scientifically rigorous and artistically imaginative in its approach to fossils of the past - and those of the future.

    Yet, while common, oak woodlands are anything but ordinary. In a book rich in illustration and suffused with wonder, author Kate Marianchild combines extensive research and years of personal experience to explore some of the marvelous plants and animals that the oak woodlands nurture. Acorn woodpeckers unite in marriages of up to ten mates and raise their young cooperatively. Ground squirrels roll in rattlesnake skins to hide their scent from hungry snakes. Manzanita's rust-colored, paper-thin bark peels away in time for the summer solstice, exposing sinuous contours that are cool to the touch even on the hottest day. Conveying up-to-the-minute scientific findings with a storyteller's skill, Marianchild introduces us to a host of remarkable creatures in a world close by, a world that rustles, hums, and sings with the sounds of wild things.

    Ranging through the stars and the myths humans have told about them for millennia, Raymo delves into "a pilgrimage in quest of the soul of the night." Chet Raymo's elegant essays link the mysterious phenomena of the night sky with the human mind and spirit, as he ranges through the realms of mythology, literature, religion, history, and anthropology. Originally published two decades ago, The Soul of the Night is a classic work that is a must for those interested in the relationship between science and faith.

    Birds of prey have an aura that few other creatures have. In the acclaimed Hawks in Flight, Pete Dunne showed what birds of prey look like. In The Wind Masters, he shows what it is like to be a bird of prey. He takes us inside the lives and minds of all thirty-four species of diurnal raptors found in North America -- hawks, falcons, eagles, vultures, the osprey, and the harrier -- and shows us how each bird sees the world, hunts its prey, finds and courts its mate, rears its young, grows up, grows old, and dies. Vividly written, and beautifully illustrated by David Sibley, The Wind Masters is a brilliant work of narrative natural history in the tradition of Peter Matthiessen's The Wind Birds and Barry Lopez's Of Wolves and Men.

    This special, large-format volume is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than two hundred species and including more than 330 new illustrations by the author. While its focus is on familiar backyard birds--blue jays, nuthatches, chickadees--it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin. David Sibley's artwork and expertise bring observed behaviors vividly to life. (For most species, the primary illustration is reproduced life-sized.) And while the text is aimed at adults--including fascinating new scientific research on the myriad ways birds have adapted to environmental changes--it is nontechnical, making it the perfect occasion for parents and grandparents to share their love of birds with young children, who will delight in the big, full-color illustrations of birds in action.

    In this beautifully illustrated book, Swedish artist and author of The Illustrated Compendium of Amazing Animal Facts, Maja Safstrom, explores the world of extinct animals. Animals of a Bygone Era features 54 extinct animals from the ancient and modern world--including well-known examples such as wooly mammoths and dodo birds, as well as lesser-known (but no less fascinating) animals like semiaquatic sea minks, marsupial Tasmanian tigers, and tiny Eurasian wild horses.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    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
