Paleoecology of Beringia


Book Description

Paleoecology of Beringia is the product of a symposium organized by its editors, sponsored by the Wenner-Gren Foundation for Anthropological Research, and held at the foundation's conference center in Burg Wartenstein, Austria, 8-17 June 1979. The focus of this volume is on the paradox central to all studies of the unglaciated Arctic during the last Ice Age: that vertebrate fossils indicate that from 45,000 to 11,000 years BP an environment considerably more diverse and productive than the present one existed, whereas the botanical record, where it is not silent, supports a far more conservative appraisal of the region's ability to sustain any but the sparsest forms of plant and animal life. The volume is organized into seven parts. Part 1 focuses on the paleogeography of the Beringia. The studies in Part 2 explore the ancient vegatation. Part 3 deals with the steppe-tundra concept and its application in Beringia. Part 4 examines the paleoclimate while Part 5 is devoted to the biology of surviving relatives of the Pleistocene ungulates. Part 6 takes up the presence of man in ancient Beringia. Part 7 assesses the paleoecology of Beringia during the last 40,000 years




American Beginnings


Book Description

During the last Ice Age, a thousand-mile-wide land bridge connected Siberia and Alaska, creating the region known as Beringia. Over twelve thousand years ago, a procession of large mammals and the humans who hunted them crossed this bridge to America. Much of the Russian evidence for this migration has until now remained largely inaccessible to American scholars. American Beginnings brings together for the first time in one volume the most up-to-date archaeological and palaeoecological evidence on Beringia from both Russia and America. "An invaluable resource. . . . It will no doubt remain the key reference book for Beringia for many years to come."—Steven Mithen, Journal of Human Evolution "Extraordinary. The fifty-six contributors . . . represent the most prominent American and Russian researchers in the region."—Choice "Publication of this well-illustrated compendium is a great service to early American and especially Siberian Upper Paleolithic archaeology."—Nicholas Saunders, New Scientist "This is a great book . . . perhaps the greatest contribution to the archaeology of Beringia that has yet been published. . . . This is the kind of book to which archaeology should aspire."—Herbert D.G. Maschner, Antiquity




Dry Creek


Book Description

With cultural remains dated unequivocally to 13,000 calendar years ago, Dry Creek assumed major importance upon its excavation and study by W. Roger Powers. The site was the first to conclusively demonstrate a human presence that could be dated to the same time as the Bering Land Bridge. As Powers and his team studied the site, their work verified initial expectations. Unfortunately, the research was never fully published. Dry Creek: The Archaeology and Paleoecology of a Late Pleistocene Alaskan Hunting Camp is ready to take its rightful place in the ongoing research into the peopling of the Americas. Containing the original research, this book also updates and reconsiders Dry Creek in light of more recent discoveries and analysis.




Human Ecology of Beringia


Book Description

Twenty-five thousand years ago, sea level fell more than 400 feet below its present position as a consequence of the growth of immense ice sheets in the Northern Hemisphere. A dry plain stretching 1,000 miles from the Arctic Ocean to the Aleutians became exposed between northeast Asia and Alaska, and across that plain, most likely, walked the first people of the New World. This book describes what is known about these people and the now partly submerged land, named Beringia, which they settled during the final millennia of the Ice Age. Humans first occupied Beringia during a twilight period when rising sea levels had not yet caught up with warming climates. Although the land bridge between northeast Asia and Alaska was still present, warmer and wetter climates were rapidly transforming the Beringian steppe into shrub tundra. This volume synthesizes current research-some previously unpublished-on the archaeological sites and rapidly changing climates and biota of the period, suggesting that the absence of woody shrubs to help fire bone fuel may have been the barrier to earlier settlement, and that from the outset the Beringians developed a postglacial economy similar to that of later northern interior peoples. The book opens with a review of current research and the major problems and debates regarding the environment and archaeology of Beringia. It then describes Beringian environments and the controversies surrounding their interpretation; traces the evolving adaptations of early humans to the cold environments of northern Eurasia, which set the stage for the settlement of Beringia; and provides a detailed account of the archaeological record in three chapters, each of which is focused on a specific slice of time between 15,000 and 11,500 years ago. In conclusion, the authors present an interpretive summary of the human ecology of Beringia and discuss its relationship to the wider problem of the peopling of the New World.




The Bering Land Bridge


Book Description

Data of geology, oceanography, paleontology, plant geography, and anthropology focus on problems and lessons of Beringia. Includes papers presented at Symposium held at VII Congress of International Association for Quaternary Research, Boulder, Colorado, 1965.




The Quaternary Period in the United States


Book Description

This book reviews advances in understanding of the past ca. two million years of Earth history - the Quaternary Period - in the United States. It begins with sections on ice and water - as glaciers, permafrost, oceans, rivers, lakes, and aquifers. Six chapters are devoted to the high-latitude Pleistocene ice sheets, to mountain glaciations of the western United States, and to permafrost studies. Other chapters discuss ice-age lakes, caves, sea-level fluctuations, and riverine landscapes. With a chapter on landscape evolution models, the book turns to essays on geologic processes. Two chapters discuss soils and their responses to climate, and wind-blown sediments. Two more describe volcanoes and earthquakes, and the use of Quaternary geology to understand the hazards they pose. The next part of the book is on plants and animals. Five chapters consider the Quaternary history of vegetation in the United States. Other chapters treat forcing functions and vegetation response at different spatial and temporal scales, the role of fire as a catalyst of vegetation change during rapid climate shifts, and the use of tree rings in inferring age and past hydroclimatic conditions. Three chapters address vertebrate paleontology and the extinctions of large mammals at the end of the last glaciation, beetle assemblages and the inferences they permit about past conditions, and the peopling of North America. A final chapter addresses the numerical modeling of Quaternary climates, and the role paleoclimatic studies and climatic modeling has in predicting future response of the Earth's climate system to the changes we have wrought.




Alaska Dinosaurs


Book Description

Anthony Fiorillo has been exploring the Arctic since 1998. For him, like many others, the Arctic holds the romance of uncharted territory, extreme conditions, and the inevitable epic challenges that arise. For Fiorillo, however, the Arctic also holds the secrets of the history of life on Earth, and its fossils bring him back field season after field season in pursuit of improving human understanding of ancient history. His studies of the rocks and fossils of the Arctic shed light on a world that once was, and provide insight into what might be.
