The Jaramillo Subchron And The Early Middle Pleistocene Transition In Continental Records From A Multidisciplinary Perspective

This book documents the agreed geological reference point for the Pleistocene boundary, and its worldwide correlation.

The Early-Middle Pleistocene transition (around 1.2 to 0.5 Ma) marks a profound shift in Earth's climate state. Low-amplitude 41 ka climate cycles, dominating the earlier part of the Pleistocene, gave way progressively to a 100 ka rhythm of increased amplitude that characterizes our present glacial-interglacial world. This volume assesses the biotic and physical response to this transition both on land and in the oceans: indeed it examines the very nature of Quaternary climate change. Milankovitch theory, palaeoceanography using isotopes and microfossils, marine organic geochemistry, tephrochronology, the record of loess and soil deposition, terrestrial vegetational change, and the migration and evolution of hominins as well as other large and small mammals, are all considered. These themes combine to explore the very origins of our present biota.

Magnetic Stratigraphy is the most comprehensive book written in the English language on the subject of magnetic polarity stratigraphy and time scales. This volume presents the entirety of the known geomagneticrecord, which now extends back about 300 million years. The book includes the results of current research on sea floor spreading, magnetic stratigraphy of the Pliocene and Pleistocene, and postulations on the Paleozoic. Also included are both historicalbackground and applications of magnetostratigraphy. Individual chapters on correlation are presented, using changes in magnetic properties and secular variation. Key Features* Discusses pioneering work in the use of marine sediments to investigate the Earths magnetic field* Serves as a guide for students wishing to begin studies in magnetostratigraphy* Provides a comprehensive guide to magnetic polarity stratigraphy including up-to-date geomagnetic polarity time scales* Correlates magnetic stratigraphics from marine and non-marine Cenozoic sequences* Details reversal history of the magnetic field for the last 350 million years* Discusses correlation using magnetic dipole intensity changes* Up-to-date correlation of biostratigraphy with magnetic stratigraphy through the late Jurassic

In this book an internationally distinguished roster of contributors considers the state of the art of the discipline of archaeology at the turn of the 21st century and charts an ambitious agenda for the future. The chapters address a wide range of topics including, paradigms, practice, and relevance of the discipline; paleoanthropology; fully modern humans; holocene hunter-gatherers; the transition to food and craft production; social inequality; warfare; state and empire formation; and the uneasy relationship between classical and anthropological archaeology.

For the first two thirds of our evolutionary history, we hominins were restricted to Africa. Dating from about two million years ago, hominin fossils first appear in Eurasia. This volume addresses many of the issues surrounding this initial hominin intercontinental dispersal. Why did hominins first leave Africa in the early Pleistocene and not earlier? What do we know about the adaptations of the hominins that dispersed - their diet, locomotor abilities, cultural abilities? Was there a single dispersal event or several? Was the hominin dispersal part of a broader faunal expansion of African mammals northward? What route or routes did dispersing populations take?

The fossil site of Untermassfeld, near the town of Meiningen in Southern Thuringia, was discovered in 1978 and has been the subject of 25 field seasons. The digs have produced a stunning array of fossil vertebrate remains in stratigraphic context, making this unquestionably one of the most important Quaternary localities in Europe. In this volume the author provides the first full synthesis of the work, bringing the results up to date, and placing them in a broad context. With some 14,000 determinable vertebrate fossils, the Untermassfeld assemblage represents the most complete assemblage of the time span 1.2-0.9 Ma BP in the Western Palaearctic.
