She entered Ah-gwah-ching State Sanatorium at Walker, Minnesota, for what she thought would be a short stay. In January, her tuberculosis spread, and she nearly died. Her recovery required many months of bed rest and medical care.Marilyn loved to write, and the story of her three-year residency at the sanatorium is preserved in hundreds of letters that she mailed back home to her parents, who could visit her only occasionally and whom she missed terribly. The letters functioned as a diary in which Marilyn articulately and candidly recorded her reactions to roommates, medical treatments, Native American nurses, and boredom. She also offers readers the singular perspective of a bed-bound teenager, gossiping about boys, requesting pretty new pajamas, and enjoying Friday evening popcorn parties with other patients.Selections from this cache of letters are woven into an informative narrative that explores the practices and culture of a midcentury tuberculosis sanatorium and fills in long-forgotten details gleaned from recent conversations with Marilyn, who "graduated" from the sanatorium and went on to lead a full, productive life.

    World-renowned dinosaur illustrator and researcher Gregory Paul provides comprehensive visual and textual coverage of the great Mesozoic animals that gave rise to the living dinosaurs, the birds. Incorporating the new discoveries and research that are radically transforming what we know about dinosaurs, this book is distinguished both by its scientific accuracy and the quality and quantity of its illustrations. It presents thorough descriptions of more than 735 dinosaur species and features more than 600 color and black-and-white images, including unique skeletal drawings, life studies, and scenic views--illustrations that depict the full range of dinosaurs, from small, feathered creatures to whale-sized supersauropods.Heavily illustrated species accounts of the major dinosaur groups are preceded by an extensive introduction that covers dinosaur history and biology, the extinction of nonavian dinosaurs, the origin of birds, and the history of dinosaur paleontology--and that also gives a taste of what it might be like to travel back to the time of the dinosaurs.The Princeton Field Guide to Dinosaurs is a must-have for anyone who loves dinosaurs, from the amateur enthusiast to the professional paleontologist.The first authoritative field guide to dinosaursCovers more than 735 speciesBeautiful, large-format volumeLavishly illustrated throughout, with more than 600 color and black-and-white drawings and figures, including: More than 130 color life studies, including scenic views Close to 450 skeletal, skull, head, and muscle drawings 8 color paleo-distribution maps Color timelineDescribes anatomy, physiology, locomotion, reproduction, and growth of dinosaurs, as well as the origin of birds and the extinction of nonavian dinosaurs

    But despite the hype, Tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right, and are among the best-studied of all dinosaurs.Tyrannosaurs started small, but over the course of 100 million years evolved into the giant carnivorous bone-crushers that continue to inspire awe in palaeontologists, screenplay writers, sci-fi novelists and the general public alike. Tyrannosaurus itself was truly impressive; it topped six tons, was more than 12m (40 feet) long, and had the largest head and most powerful bite of any land animal in history.The Tyrannosaur Chronicles tracks the rise of these dinosaurs, and presents the latest research into their biology, showing off more than just their impressive statistics - tyrannosaurs had feathers and fought and even ate each other. This book presents the science behind this research; it tells the story of the group through their anatomy, ecology and behaviour, exploring how they came to be the dominant terrestrial predators of the Mesozoic and, in more recent times, one of the great icons of biology.

    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

    Stonehenge A striking and original interpretation of the awesome Stone Age site from one of the world's foremost archaeologists on death and burial Full description

    It produced a cloud of roiling debris that blackened the sky for months as well as other geologic disasters--and triggered the demise of Tyrannosaurus rex. We know what happened largely because Walter Alvarez--synthesizing the findings of experts from a variety of scientific fields--has written a gripping story of the decades-long search for the cause of the dinosaurs' extinction. Painstakingly assembling clues from the Italian Apennines and the depths of the Pacific and presenting them with the excitement of a great novel, T. rex and the Crater of Doom is a book of undeniable importance and irresistible appeal by a major figure in contemporary science. " Engaging and witty. Read Alvarez for and excellent account of how scientists pose questions and seek to solve them." --Scientific American " First-rate...Alvarez provides the up-close tale of the comet or asteroid that wiped out the dinosaurs." --San Francisco Chronicle

    Krause is a pioneer in the revolutionary new science of archaeogenetics, archaeology augmented by revolutionary DNA sequencing technology, which has allowed scientists to uncover a new version of human history reaching back more than 100,000 years. Using this technology to re-examine human bones from the distant past, Krause has been able to map not only the genetic profiles of the dead, but also their ancient journeys.In this concise narrative he tells us their long-forgotten stories of migration and intersection. It's well known that many human populations carry genetic material from Neanderthals; but, as Krause and his colleagues discovered, we also share DNA with a newly uncovered human form, the Denisovans. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. The farmer DNA is one of the core genetic components of contemporary Europeans and European Americans. Though the first people to cross into North and South America have long been assumed to be primarily of East Asian descent, we now know that they also share DNA with contemporary Europeans and European Americans. Genetics has an unfortunate history of smuggling in racist ideologies, but our most cutting-edge science tells us that genetic categories in no way reflect national borders.Krause vividly introduces us to prehistoric cultures such as the Aurignacians, innovative artisans who carved animals, people, and even flutes from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe's most successful early settlers until they perished in the ice age. This informed retelling of the human epic confirms that immigration and genetic mingling have always defined our species and that who we are is a question of culture not genetics.

    But we long to know more: how did these animals actually behave? We are fascinated by the daily lives of our fellow creatures--how they reproduce and raise their young, how they hunt their prey or elude their predators, and more. What would it be like to see prehistoric animals as they lived and breathed?From dinosaurs fighting to their deaths to elephant-sized burrowing ground sloths, this book takes readers on a global journey deep into the earth's past. Locked in Time showcases fifty of the most astonishing fossils ever found, brought together in five fascinating chapters that offer an unprecedented glimpse at the real-life behaviors of prehistoric animals. Dean R. Lomax examines the extraordinary direct evidence of fossils captured in the midst of everyday action, such as dinosaurs sitting on their eggs like birds, Jurassic flies preserved while mating, a T. rex infected by parasites. Each fossil, he reveals, tells a unique story about prehistoric life. Many recall behaviors typical of animals familiar to us today, evoking the chain of evolution that links all living things to their distant ancestors. Locked in Time allows us to see that fossils are not just inanimate objects: they can record the life stories of creatures as fully alive as any today. Striking and scientifically rigorous illustrations by renowned paleoartist Bob Nicholls bring these breathtaking moments to life.

    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.

    In 1985 Hans von Ohain, the scientist who pioneered Nazi Germany's efforts to build a jet plane, posed the question: 'Would World War II have occured if the Luftwaffe knew it faced operational British jets instead of Spitfires?' He immediately answered, 'I, for one, think not.'Frank Whittle, working-class outsider and self-taught enthusiast, had worked out the blueprint of a completely new type of engine in 1929, only for his ideas to be blocked by bureaucratic opposition until the outbreak of war in 1939. The importance of his work was recognized too late by the government for his revolutionary engine to play a major part in World War II. After the war Whittle's dream of civilian jet-powered aircraft became a reality and Britain enjoyed a golden age of 1950's jet-powered flight.Drawing on Whittle's extensive private papers, Campbell-Smith tells the story of a stoic and overlooked British hero, a tantalizing tale of 'what might have been'.

    And despite centuries of study there is always more to know. In 2008, paleontologist John A. Long and a team of researchers revealed their discovery of a placoderm fish fossil, known as “the mother fish,” which at 380 million years old revealed the oldest vertebrate embryo—the earliest known example of internal fertilization. As Long explains, this find led to the reexamination of countless fish fossils and the discovery of previously undetected embryos. As a result, placoderms are now considered to be the first species to have had intimate sexual reproduction or sex as we know it—sort of. Inspired by this incredible find, Long began a quest to uncover the paleontological and evolutionary history of copulation and insemination. In The Dawn of the Deed, he takes readers on an entertaining and lively tour through the sex lives of ancient fish and exposes the unusual mating habits of arthropods, tortoises, and even a well-endowed (16.5 inches!) Argentine Duck. Long discusses these significant discoveries alongside what we know about reproductive biology and evolutionary theory, using the fossil record to provide a provocative account of prehistoric sex. The Dawn of the Deed also explores fascinating revelations about animal reproduction, from homosexual penguins to monogamous seahorses to the difficulties of dinosaur romance and how sexual organs in ancient shark-like fishes actually relate to our own sexual anatomy. The Dawn of the Deed is Long’s own story of what it’s like to be a part of a discovery that rewrites evolutionary history as well as an absolutely rollicking guide to sex throughout the ages in the animal kingdom. It’s natural history with a naughty wink.

    But what were and are the true potentates of our planet? Insects, says Scott Richard Shaw—millions and millions of insect species. Starting in the shallow oceans of ancient Earth and ending in the far reaches of outer space—where, Shaw proposes, insect-like aliens may have achieved similar preeminence—Planet of the Bugs spins a sweeping account of insects’ evolution from humble arthropod ancestors into the bugs we know and love (or fear and hate) today. Leaving no stone unturned, Shaw explores how evolutionary innovations such as small body size, wings, metamorphosis, and parasitic behavior have enabled insects to disperse widely, occupy increasingly narrow niches, and survive global catastrophes in their rise to dominance. Through buggy tales by turns bizarre and comical—from caddisflies that construct portable houses or weave silken aquatic nets to trap floating debris, to parasitic wasp larvae that develop in the blood of host insects and, by storing waste products in their rear ends, are able to postpone defecation until after they emerge—he not only unearths how changes in our planet’s geology, flora, and fauna contributed to insects’ success, but also how, in return, insects came to shape terrestrial ecosystems and amplify biodiversity. Indeed, in his visits to hyperdiverse rain forests to highlight the current insect extinction crisis, Shaw reaffirms just how crucial these tiny beings are to planetary health and human survival. In this age of honeybee die-offs and bedbugs hitching rides in the spines of library books, Planet of the Bugs charms with humor, affection, and insight into the world’s six-legged creatures, revealing an essential importance that resonates across time and space.
