"Meighen Island is a keystone site in the Neogene Canadian High Arctic, unique in the Beaufort Formation for its interbedded marine tongue. This volume is a comprehensive report on the biostratigraphy, age, and correlation of Meighen Island to other important Arctic localities from the standpoint of deposits exposed in the area of Bjaere Bay on the west side of the Island. The authors consider the diverse fossil macrofloras and pollen, the terrestrial and marine faunas, magnetostratigraphy, and amino acid racemization and put this site in the context of major changes in climate and geography during the Pliocene"--

This book aims to shed light on the 'Out of Africa' problem by approaching it from a different angle and proposing when during the Late Pliocene and Early Pleistocene hominid migration was most feasible and along what pathways the migrations may have occured. It represents the first use of GIS to predict and model the potential migration pathways.

This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.

This volume sheds new light on the marine fauna and geological setting of the Tjörnes Sequence, North Iceland, which is a classic site for the Pliocene and Pleistocene stratigraphy of the North Atlantic region. Readers will discover descriptions of new data collected by the editors over a period of over three decades on marine faunal assemblages and sedimentology available for palaeoenvironmental reconstructions, as well as the tectonic and stratigraphical relationships on Tjörnes Peninsula. The book includes a comprehensive account of all the collections of marine fossil invertebrate macrofossils and foraminifera known to the editors from the Tjörnes Sequence. It is expected to elucidate sedimentological and faunal changes from relatively stable Pliocene conditions to highly variable and periodically harsh climatic conditions of recurring Quaternary glaciations. The distribution, recent or fossil, of various species is recorded and pertinent ecological and biological features are also discussed. The Tjörnes Sequence records the Neogene migration of Pacific species into the North Atlantic. Researchers in geology, climate science, environmental science and earth science will find this book particularly valuable.

The plant fossil record indicates that the genus Metasequoia was widely distributed throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus has shrunk to one species with approximately 5,000 mature individuals in southeastern China’s Xiahoe Valley. This book distills the current understanding of the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

Microtine history indicates mosaic evolution and complex dispersal patterns around the Northern Hemisphere ; by reflecting this history and evaluating stage of population evolution, microtine biochronology can discriminate time periods as brief as 5,000 years.
