Book Description
“Vivid descriptions of the animals, the cave, and the scientists are complemented by the original art and photos that work together unusually well.” —Booklist What was life like millions of years ago? The answer lies deep underground, in a place once home to a ferocious predator much larger than most animals walking around today. Through photographs and detailed illustrations, readers will learn how the secrets buried in a midwestern hillside helped scientists understand early life on Earth. This book’s simple but informative format allows readers to follow along as paleontologist Matt Forir and his team of experts unravel a prehistoric mystery. “[An] account of the discovery and early exploration of Missouri’s Riverbluff Cave, the oldest found so far in this country with fossil remains . . . may excite curiosity about the Riverbluff finds.” —Kirkus Reviews

Book Description
In this engrossing and accessible book, Doug Macdougall explores the causes and effects of ice ages that have gripped our planet throughout its history, from the earliest known glaciation—nearly three billion years ago—to the present. Following the development of scientific ideas about these dramatic events, Macdougall traces the lives of many of the brilliant and intriguing characters who have contributed to the evolving understanding of how ice ages come about. As it explains how the great Pleistocene Ice Age has shaped the earth's landscape and influenced the course of human evolution, Frozen Earth also provides a fascinating look at how science is done, how the excitement of discovery drives scientists to explore and investigate, and how timing and chance play a part in the acceptance of new scientific ideas. Macdougall describes the awesome power of cataclysmic floods that marked the melting of the glaciers of the Pleistocene Ice Age. He probes the chilling evidence for "Snowball Earth," an episode far back in the earth's past that may have seen our planet encased in ice from pole to pole. He discusses the accumulating evidence from deep-sea sediment cores, as well as ice cores from Greenland and the Antarctic, that suggests fast-changing ice age climates may have directly impacted the evolution of our species and the course of human migration and civilization. Frozen Earth also chronicles how the concept of the ice age has gripped the imagination of scientists for almost two centuries. It offers an absorbing consideration of how current studies of Pleistocene climate may help us understand earth's future climate changes, including the question of when the next glacial interval will occur.

Book Description
Scientists charged with producing a map of the earth during the last ice age ultimately confirmed the theory that the earth's irregular orbital motions account for the bizarre climatic changes which bring on ice ages. This book tells the story of those periods--what they were like, why they occurred, and when the next ice age is due.

Book Description
“This lively and fascinating book is an intelligent examination of how scientific endeavor operates over time and how community life can be focused and energized. It’s also filled with portraits of colorful personalities.”—Florida Weekly "A fascinating recounting of the early discovery of a Paleolithic human and the issues that were engendered by various opposing scientific views of the validity of the discovery and its analysis."--Dennis Stanford, coauthor of Across Atlantic Ice: The Origin of America's Clovis Culture "Since the site's discovery long ago, the complete story of the Old Vero Site has never been told. This is an informative and entertaining account of this remarkable site and its history in American archaeology."--Thomas D. Dillehay, author of The Settlement of the Americas: A New Prehistory "Johnson has thoroughly investigated, and transformed into a very readable narrative, an entire century of accumulated knowledge about the research, controversy, and curiosity surrounding the Old Vero archaeological site."--Barbara A. Purdy, author of Florida's People During the Last Ice Age "An engaging account of the first Paleoindian site discovered in eastern North America."--Robert S. Carr, author of Digging Miami "Johnson skillfully weaves a tale of prehistoric life in Florida with the 100-year search to understand that long lost world at the Vero Site."--Andy Hemmings, Florida Atlantic University In 1916, to the shock of the scientific community and the world at large, a Florida geologist discovered human remains mixed with the bones of prehistoric animals in a Vero Beach canal and proclaimed that humans had lived in North America since the Ice Age. These new findings by Elias Sellards flew in the face of prevailing wisdom, which held that humans first came to the continent only 6,000 years ago. His claim was snubbed by the top scientists of his day, he was laughed out of the state, Vero's fame declined, and the skull Sellards found--famously known as "Vero Man "--was lost. An Ice Age Mystery tells the story of Sellards's exciting find and the controversy it sparked. In the years that followed, other archaeological discoveries and the rise of radiocarbon dating established that humans did arrive in North America earlier than previously thought. The skull, however, was never recovered, and many people began to wonder: What exactly had Sellards found at Vero? And what else might be buried there? One hundred years after the first Vero discovery, construction plans threatened to cover up the legendary dig site, and a band of citizens and archaeologists protested. Excavations were reopened. Archaeologists uncovered 14,000-year-old burnt mammal bones and charcoal, signs of a human presence, and found further evidence to indicate a continuous human occupation of the site for several thousand years. Prior to the latest excavations an etching on a bone possibly 13,000 years old was discovered that could be the oldest piece of art in America. Sellards had been right all along. Many questions still remain. Who were these people? Where did they come from? And how did they get here? This book draws readers into the past, present, and future of one of the most historic discoveries in American archaeology.

Book Description
A mesmerizing overview of the world as it was when glaciers covered the earth and long-extinct creatures like the woolly mammoths and saber-toothed cats battled to survive. Go back 20,000 years ago to a time of much colder global temperatures when glaciers and extensive sheets of ice covered much of our planet. As these sheets traveled, they caused enormous changes in the Earth's landscape and climate, leading to the evolution of creatures such as giant armadillos, saber-toothed cats, and woolly mammoths as well as club-wielding Neanderthals and later the cleverer modern humans. Nico Medina re-creates this harsh ancient world in a vivid and easy-to-read narrative.

Book Description
Earth's past is littered with the mysterious and unexplained: the pyramids, Easter Island, Stonehenge, dinosaurs, and the list goes on and on as science looks for clues to decipher these puzzles. One such mystery surrounds the now-extinct creature called the woolly mammoth. Author and meteorologist Michael Oard has studied the mammoth and its equally mysterious time period, the Ice Age, for many years and has come to some fascinating conclusions to help lift the fog engulfing the facts. Some of the questions he addresses include: What would cause the summer temperatures of the northern United States and European to plummet more than 50 degrees Fahrenheit? Why did mammoths become extinct across the entire earth at the same time as many other large mammals? Why are the mammoth carcasses found generally in standing positions? How could large lakes exist in what are today very dry, desert-like places? What was the source of the abnormal of moisture necessary for heavy snow? What caused the cold summer temperatures and heavy snowfall to persist for hundreds of years? In logical progression many other Ice Age topics are explained including super Ice Age floods, ice cores, man in the Ice Age, and the number of ice ages. This is one of the most difficult eras in geological history for a uniformitarian scientist (one who believes the earth evolved by slow processes over millions of years) to explain, simply because long ages of evolution cannot explain it. Provided here are plausible explanations of the seemingly unsolvable mysterious about the Ice Age and the woolly mammoths - Frozen in Time.

Book Description
Some of the oldest art in the world is the subject of this riveting and beautiful book. Paul Bahn and Jean Vertut explore carved objects and wall art discoveries from the Ice Age, covering the period from 300,000 B.P. to 10,000 B.P., and their collaboration marks a signal event for archaeologists and lay readers alike. Utilizing the most modern analytical techniques in archaeology, Bahn presents new accounts of Russian caves only recently opened to foreign specialists; the latest discoveries from China and Brazil; European cave finds at Cosquer, Chauvet, and Covaciella; and the recently discovered sites in Australia. He also studies sites in Africa, India, and the Far East. Included are the only photographic images of many caves that are now closed to protect their fragile environments. A separate chapter in the book examines art fakes and forgeries and relates how such deceptions have been exposed. The beliefs and preoccupations of Paleolithic peoples resonate throughout this book: the importance of the hunt and the magic and shamanism surrounding it, the recording of the seasons, the rituals of sex and fertility, the cosmology and associated myths. Yet enigmas and mysteries emerge as well, particularly as new analytical techniques raise new questions and cast doubt on our earlier suppositions. A comprehensive, up-to-date analysis of all that has been discovered about Ice Age art, Bahn and Vertut's book offers a visually rich link with the past.
