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.

    It sustainably provided enough food to allow cities, nations, and empires to grow, but it did so with a different emphasis. Where agriculture encouraged stability, fishing demanded movement. It frequently required a search for new and better fishing grounds; its technologies, centered on boats, facilitated movement and discovery; and fish themselves, when dried and salted, were the ideal food—lightweight, nutritious, and long-lasting—for traders, travelers, and conquering armies. This history of the long interaction of humans and seafood tours archaeological sites worldwide to show readers how fishing fed human settlement, rising social complexity, the development of cities, and ultimately the modern world.

    Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more “new” species were named than in all prior history. With these discoveries—and the most recent controversies—in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story.

    Since then, deformed frogs have been turning up in lakes around the world. Written by the only journalist granted access to secret hot spots where these deformed frogs are tested, and brainstorming sessions among the researchers, this compelling, fast-paced narrative is the first to offer a complete picture of what is quite possibly a global catastrophe in the making.

    Today we can see a recreation of the making of the Laetoli footprints at the American Museum of Natural History, in a stunning diorama which depicts two of our human forebears walking side by side through a snowy landscape of volcanic ash. But how do we know what these three-million-year-old relatives looked like? How have we reconstructed the eons-long journey from our first ancient steps to where we stand today? In short, how do we know what we think we know about human evolution? In The Fossil Trail, Ian Tattersall, the head of the Anthropology Department at the American Museum of Natural History, takes us on a sweeping tour of the study of human evolution, offering a colorful history of fossil discoveries and a revealing insider's look at how these finds have been interpreted--and misinterpreted--through time. All the major figures and discoveries are here. We meet Lamarck and Cuvier and Darwin (we learn that Darwin's theory of evolution, though a bombshell, was very congenial to a Victorian ethos of progress), right up to modern theorists such as Niles Eldredge and Stephen Jay Gould. Tattersall describes Dubois's work in Java, the many discoveries in South Africa by pioneers such as Raymond Dart and Robert Broom, Louis and Mary Leakey's work at Olduvai Gorge, Don Johanson's famous discovery of Lucy (a 3.4 million-year-old female hominid, some 40% complete), and the more recent discovery of the Turkana Boy, even more complete than Lucy, and remarkably similar to modern human skeletons. He discusses the many techniques available to analyze finds, from fluorine analysis (developed in the 1950s, it exposed Piltdown as a hoax) and radiocarbon dating to such modern techniques as electron spin resonance and the analysis of human mitochondrial DNA. He gives us a succinct picture of what we presently think our family tree looks like, with at least three genera and perhaps a dozen species through time (though he warns that this greatly underestimates the actual diversity of hominids over the past two million or so years). And he paints a vivid, insider's portrait of paleoanthropology, the dogged work in the broiling sun, searching for a tooth, or a fractured corner of bone, amid stone litter and shadows, with no guarantee of ever finding anything. And perhaps most important, Tattersall looks at all these great researchers and discoveries within the context of their social and scientific milleu, to reveal the insidious ways that the received wisdom can shape how we interpret fossil findings, that what we expect to find colors our understanding of what we do find. Refreshingly opinionated and vividly narrated, The Fossil Trail is the only book available to general readers that offers a full history of our study of human evolution. A fascinating story with intriguing turns along the way, this well-illustrated volume is essential reading for anyone curious about our human origins.

    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.

    Thanks to cartoons and folk accounts we have a distorted view of these other humans - for that is what they were. We think of them as crude and clumsy and not very bright, easily driven to extinction by the lithe, smart modern humans that came out of Africa some 100,000 years ago.But was it really as simple as that? Clive Finlayson reminds us that the Neanderthals were another kind of human, and their culture was not so very different from that of our own ancestors. In this book, he presents a wider view of the events that led to the migration of the moderns into Europe, what might have happened during the contact of the two populations, and what finally drove the Neanderthals to extinction. It is a view that considers climate, ecology, and migrations of populations, as well as culture and interaction.His conclusion is that the destiny of the Neanderthals and the Moderns was sealed by ecological factors and contingencies. It was a matter of luck that we survived and spread while the Neanderthals dwindled and perished. Had the climate not changed in our favour some 50 million years ago, things would have been very different.There is much current research interest in Neanderthals, much of it driven by attempts to map some of their DNA. But it's not just a question of studying the DNA. The rise and fall of populations is profoundly moulded by the larger scale forces of climate and ecology. And it is only by taking this wider view that we can fully understand the course of events that led to our survival and their demise. The fact that Neanderthals survived until virtually yesterday makes our relationship with them and their tragedy even more poignant. They almost made it, after all.

    They have also become vibrant educational centers, full of engaging exhibits that share those discoveries with students and an enthusiastic general public.   At the heart of it all from the very start have been curators. Yet after three decades as a natural history curator, Lance Grande found that he still had to explain to people what he does. This book is the answer—and, oh, what an answer it is: lively, exciting, up-to-date, it offers a portrait of curators and their research  like none we’ve seen, one that conveys the intellectual excitement and the educational and social value of curation. Grande uses the personal story of his own career—most of it spent at Chicago’s storied Field Museum—to structure his account as he explores the value of research and collections, the importance of public engagement, changing ecological and ethical considerations, and the impact of rapidly improving technology. Throughout, we are guided by Grande’s keen sense of mission, of a job where the why is always as important as the what.   This beautifully written and richly illustrated book is a clear-eyed but loving account of natural history museums, their curators, and their ever-expanding roles in the twenty-first century.

    In this classic work Anne Sayre, a journalist and close friend of Franklin, puts the record straight.

    Here and there, we can supplement these meager scraps by the use of biochemical markers or geochemical signatures that add useful information, but, even with such additional help, our reconstructions and our models of descent are often tentative. For the fossil record is, as we have seen, as biased as it is incomplete. But fragmentary, selective, and biased though it is, the fossil record, with all its imperfections, is still a treasure. Though whole chapters are missing, many pages lost, and the earliest pages so damaged as to be, as yet, virtually unreadable, this--the greatest biography of all--is one in whose closing pages we find ourselves.--from OriginsIn Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.Rhodes's accessible and extensively illustrated treatment of the origins narrative describes the nature of the search for prehistoric life, the significance of geologic time, the origin of life, the emergence and spread of flora and fauna, the evolution of primates, and the emergence of modern humans.

    Through the remains of funerary rituals we learn not only about prehistoric people's attitudes toward death and the afterlife but also about their culture, social system, and world view. This ambitious book reviews the latest research in this huge and important field and describes the sometimes controversial interpretations that have led to our understanding of life and death in the distant past.Mike Parker Pearson draws on case studies from different periods and locations throughout the world—the Paleolithic in Europe and the Near East, the Mesolithic in northern Europe, and the Iron Age in Asia and Europe. He also uses evidence from precontact North America, ancient Egypt, and Madagascar, as well as from the Neolithic and Bronze Age in Britain and Europe, to reconstruct vivid pictures of both ancient and not so ancient funerary rituals. He describes the political and ethical controversies surrounding human remains and the problems of reburial, looting, and war crimes.The Archaeology of Death and Burial provides a unique overview and synthesis of one of the most revealing fields of research into the past, which creates a context for several of archaeology's most breathtaking discoveries—from Tutankhamen to the Ice Man. This volume will find an avid audience among archaeologists, anthropologists, historians, and others who have a professional interest in, or general curiosity about, death and burial.

    This compelling book introduces a bold new theory on this unsolved mystery. Author Richard Klein reexamines the archaeological evidence and brings in new discoveries in the study of the human brain. These studies detail the changes that enabled humans to think and behave in far more sophisticated ways than before, resulting in the incredibly rapid evolution of new skills. Richard Klein has been described as "the premier anthropologist in the country today" by Evolutionary Anthropology. Here, he and coauthor Blake Edgar shed new light on the full story of a truly fascinating period of evolution.Richard G. Klein, PhD (Palo Alto, CA), is a Professor of Anthropology at Stanford University. He is the author of the definitive academic book on the subject of the origins of human culture, The Human Career. Blake Edgar (San Francisco, CA) is the coauthor of the very successful From Lucy to Language, with Dr. Donald Johanson. He has written extensively for Discover, GEO, and numerous other magazines.

    Packed with fascinating facts and insights, the book also looks to the future and asks if the crisis of climate change is one challenge too far for humans.
