Osseous Projectile Weaponry
By Michelle C. Langley. 2016
This volume presents the current state of knowledge on the osseous projectile weaponry that was produced by Pleistocene cultures across…
the globe. Through cross-cultural and temporal comparison of manufacturing methods, design, use methods, and associated technology, chapters in this volume identify and discuss differences and similarities between these Pleistocene cultures. The central research questions addressed in this volume include: (a) how did osseous weaponry technology develop and change through time and can these changes be tied to environmental and/or social influences?; (b) how did different Pleistocene cultures design and adapt their osseous weaponry technology to their environment as well as changes in that environment?; and (c) can we identify cultural interaction between neighboring groups through the analysis of osseous weapons technology -- and if so -- can we use these items to track the movement of peoples and/or ideas across the landscape? Through addressing these three central research questions, this volume creates an integrated understanding of osseous technology during a vital period in Modern Human cultural development which will be useful for students and advanced researchers alike.Evolution of the Vertebrate Ear
By Jennifer A. Clack, Arthur N. Popper, Richard R Fay. 2016
The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a…
volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.In The Blink Of An Eye
By Andrew Parker. 2003
About 550 million years ago, there was literally an explosion of life forms, as all the major animal groups suddenly…
and dramatically appeared. Although several books have been written about this surprising event, known as the Cambrian explosion, none has explained why it occurred. Indeed, none was able to. Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's controversial but increasingly accepted "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Drawing on evidence not just from biology, but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating account of a young scientist's intellectual journey, and a celebration of the scientific method.Stratigraphic Paleobiology: Understanding the Distribution of Fossil Taxa in Time and Space
By Mark E, Patzkowsky, Steven Holland. 2012
Whether the fossil record should be read at face value or whether it presents a distorted view of the history…
of life is an argument seemingly as old as many fossils themselves. In the late 1700s, Georges Cuvier argued for a literal interpretation, but in the early 1800s, Charles Lyell's gradualist view of the earth's history required a more nuanced interpretation of that same record. To this day, the tension between literal and interpretive readings lies at the heart of paleontological research, influencing the way scientists view extinction patterns and their causes, ecosystem persistence and turnover, and the pattern of morphologic change and mode of speciation. With Stratigraphic Paleobiology, Mark E. Patzkowsky and Steven M. Holland present a critical framework for assessing the fossil record, one based on a modern understanding of the principles of sediment accumulation. Patzkowsky and Holland argue that the distribution of fossil taxa in time and space is controlled not only by processes of ecology, evolution, and environmental change, but also by the stratigraphic processes that govern where and when sediment that might contain fossils is deposited and preserved. The authors explore the exciting possibilities of stratigraphic paleobiology, and along the way demonstrate its great potential to answer some of the most critical questions about the history of life: How and why do environmental niches change over time? What is the tempo and mode of evolutionary change and what processes drive this change? How has the diversity of life changed through time, and what processes control this change? And, finally, what is the tempo and mode of change in ecosystems over time?Frozen Fauna of the Mammoth Steppe: The Story of Blue Babe
By R. Dale Guthrie. 1990
Frozen mammals of the Ice Age, preserved for millennia in the tundra, have been a source of fascination and mystery…
since their first discovery over two centuries ago. These mummies, their ecology, and their preservation are the subject of this compelling book by paleontologist Dale Guthrie. The 1979 find of a frozen, extinct steppe bison in an Alaskan gold mine allowed him to undertake the first scientific excavation of an Ice Age mummy in North America and to test theories about these enigmatic frozen fauna. The 36,000-year-old bison mummy, coated with blue mineral crystals, was dubbed "Blue Babe. " Guthrie conveys the excitement of its excavation and shows how he made use of evidence from living animals, other Pleistocene mummies, Paleolithic art, and geological data. With photographs and scores of detailed drawings, he takes the reader through the excavation and subsequent detective work, analyzing the animal's carcass and its surroundings, the circumstances of its death, its appearance in life, the landscape it inhabited, and the processes of preservation by freezing. His examination shows that Blue Babe died in early winter, falling prey to lions that inhabited the Arctic during the Pleistocene era. Guthrie uses information gleaned from his study of Blue Babe to provide a broad picture of bison evolutionary history and ecology, including speculations on the interactions of bison and Ice Age peoples. His description of the Mammoth Steppe as a cold, dry, grassy plain is based on an entirely new way of reading the fossil record.Applications of Paleoenvironmental Techniques in Estuarine Studies (Developments in Paleoenvironmental Research #Volume 20)
By Kaarina Weckstr m, Krystyna Saunders, Peter Gell, C Skilbeck. 2017
The aim of this edited volume is to introduce the scientific community to paleoenvironmental studies of estuaries, to highlight the…
types of information that can be obtained from such studies, and to promote the use of paleoenvironmental studies in estuarine management. Readers will learn about the the application of different paleoecological approaches used in estuaries that develop our understanding of their response to natural and human influences. Particular attention is given to the essential steps required for undertaking a paleoecological study, in particular with regard to site selection, core extraction and chronological techniques, followed by the range of indicators that can be used. A series of case studies are discussed in the book to demonstrate how paleoecological studies can be used to address key questions, and to sustainably manage these important coastal environments in the future. This book will appeal to professional scientists interested in estuarine studies and/or paleoenvironmental research, as well as estuarine managers who are interested in the incorporation of paleoenvironmental research into their management programs.A Brief History of South American Metatherians: Evolutionary Contexts and Intercontinental Dispersals (Springer Earth System Sciences)
By Michael Woodburne, Francisco Goin, Ana Zimicz, Gabriel Martin, Laura Chornogubsky. 2016
This book summarizes major aspects of the evolution of South American metatherians, including their epistemologic, phylogenetic, biogeographic, faunal, tectonic, paleoclimatic,…
and metabolic contexts. A brief overview of the evolution of each major South American lineage ("Ameridelphia", Sparassodonta, Didelphimorphia, Paucituberculata, Microbiotheria, and Polydolopimorphia) is provided. It is argued that due to physiological constraints, metatherian evolution closely followed the conditions imposed by global temperatures. In general terms, during the Paleocene and the early Eocene multiple radiations of metatherian lineages occurred, with many adaptive types exploiting insectivorous, frugivorous, and omnivorous adaptive zones. In turn, a mixture of generalized and specialized types, the latter mainly exploiting carnivorous and granivorous-folivorous adaptive zones, characterized the second half of the Cenozoic. In both periods, climate was the critical driver of their radiation and turnovers.A Brief History of South American Metatherians: Evolutionary Contexts and Intercontinental Dispersals (Springer Earth System Sciences)

By Neal S. Gupta. 2014
This book provides an overview, research compendium and an introduction to the science of molecular paleontology, including literature overview for…
non-geochemists. Analytical methods employed are included as a part of each chapter that underpin this branch of paleontology and indeed geochemistry. The primary usefulness of this volume is for organic geochemists, molecular palaeontologists, and molecular archeologists. Researchers, graduate students and academics interested in astrobiology from a paleontological perspective may also find this to be valuable.Atlas of Taphonomic Identifications: 1001+ Images of Fossil and Recent Mammal Bone Modification (Vertebrate Paleobiology and Paleoanthropology #0)
By Peter Andrews, Yolanda Fernández-Jalvo. 2016
The aim of the atlas is to provide images of taphonomic modifications, making it as comprehensive as possible with evidence…
presently available. This volume is intended both as a field guide for identifying taphonomic modifications in the field, and for use in the laboratory when collections of fossils are being analyzed. Images in the book are a combination of scanning electron micrographs, regular photographs, cross-sections of bones and line drawings and graphs. By providing good quality illustrations of taphonomic modifications, with links between similar types of modification, the atlas provides a reference source for identifying the agents responsible for the modifications, the processes by which they were formed, and the potential bias introduced by the processes. The authors also aim to emphasize on the directions they consider taphonomic studies should be headed. Firstly, we should seek to quantify the degree of bias introduced into a fossil fauna and to take account of this bias before interpreting the palaeoecology of the fossil site. Secondly, we should recognize that taphonomic modifications increase the information encoded in fossils by identifying perimortem and postmortem context s. This provides a more dynamic and realistic view of the past.Atlas of Taphonomic Identifications: 1001+ Images of Fossil and Recent Mammal Bone Modification (Vertebrate Paleobiology and Paleoanthropology #0)

exposures along the coast of Southwestern South America (Southern Brazil, Uruguay, Argentina) are essentially the same than those that inhabit the region today, leading to the assumption that no important change in the distribution of the faunas since Pleistocene times has occurred. However, the good taxonomic and temporal resolution reached in the last years, allowed us to detect some biogeographic changes, although traditional biogeographic units remain the same (i.e. Magellanic and Argentinean Provinces). These modifications involve mainly variations in the taxonomic composition of the assemblages and in the southern boundaries of some species distributions (extralimital species), today retracted northwards. These changes are related to southward shifts of the warm waters of the Brazilian Current, correlated with global warm peaks. This phenomenon was more intense in the Late Pleistocene (MIS 5e) and in the Holocene between ca. 6500-3500 14C yr.Climatic and Environmental History of Isla de los Estados, Argentina (SpringerBriefs in Earth System Sciences #0)

Estados. The research includes their doctoral thesis and many published scientific papers related to the island. The book is divided into two principal parts. The first part covers different social and natural aspects of this remote island and includes chapters on the scientific and historical background, physiography with topographical and hydrographical descriptions, climate and oceanographic circulation, vegetation and geology (including stratigraphy, structural geology and geological history). The second part comprises a reconstruction of the paleoenvironmental, paleoclimatic and paleogeographic history of the island from the Last Glacial Maximum to the present, correlating with other paleoecological records from the southern part of Isla Grande de Tierra del Fuego and Patagonia. This second part also includes a geomorphological chapter with a characterization of the principal erosive glacial landforms on Isla de los Estados constructed by means of morphometric analysis, inventories, maps, paleogeographic and glacial models, and a paleoecological chapter evaluating the palaeoenvironment and palaeoclimatic conditions that prevailed during the Late Pleistocene-Holocene times based on pollen and diatom analysis from three 14C-dated peat bogs and lakes. Finally, the book concludes with a review of the island's archaeology and the relationship between the palaeoenvironmental history and human occupation of this island.Climatic and Environmental History of Isla de los Estados, Argentina (SpringerBriefs in Earth System Sciences #0)

coelurosaurians that most closely approaches the common ancestor of birds. The last 20 years witnessed the discovery of a wide array of avian-like theropods that has considerably amplified the anatomical disparity among deinonychosaurians, some of which resemble Archaeopteryx more than Deinonychus. Among these newly discovered theropods that show remarkable bird-like characteristics are the four-winged theropods Microraptor and Anchiornis, and the unenlagiids Unenlagia, Buitreraptor, and Rahonavis. A bizarre group of minute-sized coelurosaurs, the Scansoriopterygidae, also exhibits some avian similarities that lead some authors to interpret them as more closely related to birds than other dinosaurs. With the aim to explore the phylogenetic relationships of these coelurosaurians and birds, we merged recently published integrative databases, resulting in significant changes in the topological distribution of taxa within Paraves. We present evidence that Dromaeosauridae, Microraptoria, Unenlagiidae, and Anchiornis + Xiaotingia form successive sister taxa of Aves, and that the Scansoriopterygidae are basal coelurosaurians not closely related to birds. The implications in the evolutionary sequence of anatomical characters leading to birds, including the origin of flight, are also considered in light of this new phylogenetic hypothesis.Anoxia: Evidence for Eukaryote Survival and Paleontological Strategies (Cellular Origin, Life in Extreme Habitats and Astrobiology #21)
By Joseph Seckbach, Joan M. Bernhard, Alexander Altenbach. 2011
ANOXIA defines the lack of free molecular oxygen in an environment. In the presence of organic matter, anaerobic prokaryotes produce…
compounds such as free radicals, hydrogen sulfide, or methane that are typically toxic to aerobes. The concomitance of suppressed respiration and presence of toxic substances suggests these habitats are inhospitable to Eukaryota. Ecologists sometimes term such environments 'Death Zones'. This book presents, however, a collection of remarkable adaptations to anoxia, observed in Eukaryotes such as protists, animals, plants and fungi. Case studies provide evidence for controlled beneficial use of anoxia by, for example, modification of free radicals, use of alternative electron donors for anaerobic metabolic pathways, and employment of anaerobic symbionts. The complex, interwoven existence of oxic and anoxic conditions in space and time is also highlighted as is the idea that eukaryotic inhabitation of anoxic habitats was established early in Earth history.Continuity and Discontinuity in the Peopling of Europe: One Hundred Fifty Years of Neanderthal Study (Vertebrate Paleobiology and Paleoanthropology)

Since the Western world first became aware of the existence of Neanderthals, this Pleistocene human has been a regular focus…
of interest among specialists and also among the general public. In fact, we know far more about Neanderthals than we do about any other extinct human population. Furthermore, over the past 150 years no other palaeospecies has been such a constant source of discussion and fierce debate among palaeoanthropologists and archaeologists. This book presents the status of our knowledge as well as the methods and techniques used to study this extinct population and it suggests perspectives for future research.Carbonate Depositional Systems: The Bahamas, Belize and the Persian/Arabian Gulf

energy and hydrocarbon reservoirs. Complex interaction of physical and chemical parameters with biological parameters determines the architecture and composition of carbonate sedimentary bodies. This book closes some of the still existing gaps in our understanding of the influence and interplay of physical, chemical, and biological parameters with carbonate sedimentation. An understanding of this interaction is not only required for reliable prediction of reservoir quality but also for a robust interpretation of environmental conditions in the past and the present. It is written by geologists for geologists in order to provide an easily accessible overview of the large amount of relevant information provided by the neighbouring sciences. The approach of the book is to document the modern depositional environments of three classical areas of carbonate deposition, each characteristic for a specific sedimentological setting (isolated platform, attached shelf, ramp) in order to assess both the range of physical, biological and chemical parameters and their sedimentary response. This book presents a comprehensive compilation based on data from published work and unpublished theses, and the integration of these data in order to extract previously undiscovered relationships between the discussed parameters and carbonate deposition.
