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.

    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.

    

    

    Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders.

    Open 365 days a year and unrestricted by the constraints of physical space, each title in this series is organized into galleries that display more than 200 full-color specimens accompanied by lively, informative text. Offering hours of learning, this first title within the series "Animalium" presents the animal kingdom in glorious detail with illustrations from Katie Scott, an unparalleled new talent.

    The complex behavior of birds recounted here demonstrates that birds have sophisticated mental abilities previously unrecognized by conventional avian research. Ackerman supports her thesis with descriptions of the behavior of an entertaining variety of birds from across the world. She brings scientific research alive with personal field observations and accounts of her encounters with colorful and fascinating birds. Throughout, Ackerman reminds readers that birds are thinking beings--their brains are wired differently than those of mammals, giving them increased brain power despite their small size. She further makes the case that bird intelligence shows that humankind is not alone in using language and tools or constructing complex structures and manipulating other creatures.

    Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special. Surveying a vast field from initial bipedality to language and intelligence, Tattersall argues that Homo sapiens acquired a winning combination of traits that was not the result of long-term evolutionary refinement. Instead, the final result emerged quickly, shocking our world and changing it forever.

    With artwork from Katie Scott of Animalium fame, Botanicum gives readers the experience of a fascinating exhibition from the pages of a beautiful book. From perennials to bulbs to tropical exotica, Botanicum is a wonderful feast of botanical knowledge complete with superb cross sections of how plants work.

    The largest cat in the Americas, it has survived an onslaught of environmental and human threats partly because of an evolutionary history unique among wild felines, but also because of a power and indomitable spirit so strong, the jaguar has shaped indigenous cultures and the beliefs of early civilizations on two continents. In An Indomitable Beast: The Remarkable Journey of the Jaguar, big-cat expert Alan Rabinowitz shares his own personal journey to conserve a species that, despite its past resilience, is now on a slide toward extinction if something is not done to preserve the pathways it prowls through an ever-changing, ever-shifting landscape dominated by humans. Rabinowitz reveals how he learned from newly available genetic data that the jaguar was a single species connected genetically throughout its entire range from Mexico to Argentina, making it unique among all other large carnivores in the world. In a mix of personal discovery and scientific inquiry, he sweeps his readers deep into the realm of the jaguar, offering fascinating accounts from the field. Enhanced with maps, tables, and color plates, An Indomitable Beast brings important new research to life for scientists, anthropologists, and animal lovers alike. This book is not only about jaguars, but also about tenacity and survival. From the jaguar we can learn better strategies for saving other species and also how to save ourselves when faced with immediate and long-term catastrophic changes to our environment.

    These small fish form a species flock -- closely related species that have descended from a common ancestor and radiated, or fanned, into different specializations -- that is the most spectacular in the world, fascinating anatomists, ecologists, ethologists, and evolutionary biologists alike. The process of speciation was still under way until just recently, when the introduction of the large, predatory Nile perch so disrupted the Lake's intricate ecosystem that the glorious spectrum of cichlids has almost vanished. Darwin's Dreampond tells the evolutionary story of the extraordinary "furu" and the battlefield leading to extinction. Tijs Goldschmidt skillfully blends a masterful discussion of the principles of neo-Darwinian evolution and speciation with a history of Lake Victoria's ecosystem. The science unfolds in the context of the engaging first-person narrative of Goldschmidt's adventures and misadventures as a field researcher. An astute observer and a clear and witty writer, he warmly portrays the colors and textures of the landscapes and the lives of the local people as he interacts with them during the course of his fieldwork.

    The pictorial models are useful in understanding relationships. The models also abound in descriptive detail.

    How they got here, persevered, and ultimately thrived is a story that resonates from the Pleistocene to our modern era. The lower sea levels of the Ice Age exposed a vast land bridge between Asia and North America, but the land bridge was not the only way across. Different people arrived from different directions, and not all at the same time.The first explorers of the New World were few, their encampments fleeting. The continent they reached had no people but was inhabited by megafauna--mastodons, giant bears, mammoths, saber-toothed cats, five-hundred-pound panthers, enormous bison, and sloths that stood one story tall. The first people were hunters--Paleolithic spear points are still encrusted with the proteins of their prey--but they were wildly outnumbered and many would themselves have been prey to the much larger animals.Atlas of a Lost World chronicles the last millennia of the Ice Age, the violent oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans' chances for survival. A blend of science and personal narrative reveals how much has changed since the time of mammoth hunters, and how little. Across unexplored landscapes yet to be peopled, readers will see the Ice Age, and their own age, in a whole new light.
