Climatic and Environmental History of Isla de los Estados, Argentina (SpringerBriefs in Earth System Sciences #0)
Par Juan Federico Ponce, Marilén Fernández. 2014
This book is the result of ten years' of scientific research carried out by the authors on Isla de los…
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.Although consensus exists among researchers that birds evolved from coelurosaurian theropods, paleontologists still debate the identification of the group of…
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)
Par 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)
Par Gerd-Christian Weniger, Silvana Condemi. 2010
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
Par Bernhard M. Riegl, Gregor P. Eberli, Hildegard Westphal. 2009
Carbonate sediments are of increasing relevance for archives of past environmental conditions and for economical reasons in areas of geothermal…
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.Carbonate Depositional Systems: The Bahamas, Belize and the Persian/Arabian Gulf

Par Christian Klug, Dieter Korn, Kenneth De Baets, Isabelle Kruta, Royal H. Mapes. 2015
This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model…
to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of new fossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.Ammonoid Paleobiology: From Anatomy To Ecology (Topics in Geobiology #43)

Par Luca Basilone. 2018
This book offers as comprehensive an overview as possible of the lithostratigraphy of the Italian region of Sicily, taking into…
account the multiplicity of formational and terminological variability developed over more than a century of studies and publications. It presents stratigraphic terminology, the geological lexicon and the main stratigraphic subdivisions that are not familiar to Sicilian geologists. The new stratigraphic methods and the use of formations as mapping units have prompted the acquisition of new lithostratigraphic data, and a review of the previous units and their comparison with the new collected data, enabling the definition of a number of new lithostratigraphic units. The book summarizes the results in 77 worksheets containing the most important information regarding the lithological, sedimentological and microfacies characteristics, the measured thicknesses, areal extent and the regional aspects, the paleoenvironmental, paleogeographic and paleo-tectonics setting, compiled according to standard procedures and nomenclature rules provided by the International Commission on Stratigraphy (ICS).Discovering the Mammoth: A Tale Of Giants, Unicorns, Ivory, And The Birth Of A New Science
Par John J. McKay. 2018
The fascinating saga of solving the mystery of this ancient animal who once roamed the north country—and has captivated our…
collective imagination ever since. Today, we know that a mammoth is an extinct type of elephant that was covered with long fur and lived in the north country during the ice ages. But how do you figure out what a mammoth is if you have no concept of extinction, ice ages, or fossils? Long after the last mammoth died and was no longer part of the human diet, it still played a role in human life. Cultures around the world interpreted the remains of mammoths through the lens of their own worldview and mythology. When the ancient Greeks saw deposits of giant fossils, they knew they had discovered the battle fields where the gods had vanquished the Titans. When the Chinese discovered buried ivory, they knew they had found dragons’ teeth. But as the Age of Reason dawned, monsters and giants gave way to the scientific method. Yet the mystery of these mighty bones remained. How did Enlightenment thinkers overcome centuries of myth and misunderstanding to reconstruct an unknown animal? The journey to unravel that puzzle begins in the 1690s with the arrival of new type of ivory on the European market bearing the exotic name "mammoth." It ends during the Napoleonic Wars with the first recovery of a frozen mammoth. The path to figuring out the mammoth was traveled by merchants, diplomats, missionaries, cranky doctors, collectors of natural wonders, Swedish POWs, Peter the Great, Ben Franklin, the inventor of hot chocolate, and even one pirate. McKay brings together dozens of original documents and illustrations, some ignored for centuries, to show how this odd assortment of characters solved the mystery of the mammoth and, in doing so, created the science of paleontology.Humans, Animals, and the Craft of Slaughter in Archaeo-Historic Societies
Par Krish Seetah. 2019
In this book, Krish Seetah uses butchery as a point of departure for exploring the changing historical relationships between animal…
utility, symbolism, and meat consumption. Seetah brings together several bodies of literature - on meat, cut marks, craftspeople, and the role of craft in production - that have heretofore been considered in isolation from one another. Focusing on the activity inherent in butcher, he describes the history of knowledge that typifies the craft. He also provides anthropological and archaeological case studies which showcase examples of butchery practices in varied contexts that are seldom identified with zooarchaeological research. Situating the relationship between practice, practitioner, material and commodity, this imaginative study offers new insights into food production, consumption, and the craft of cuisine.Biosignatures for Astrobiology (Advances in Astrobiology and Biogeophysics)
Par Frances Westall, Barbara Cavalazzi. 2019
This book aims at providing a brief but broad overview of biosignatures. The topics addressed range from prebiotic signatures in…
extraterrestrial materials to the signatures characterising extant life as well as fossilised life, biosignatures related to space, and space flight instrumentation to detect biosignatures either in situ or from orbit. The book ends with philosophical reflections on the implications of life elsewhere. In the 15 chapters written by an interdisciplinary team of experts, it provides both detailed explanations on the nature of biosignatures as well as useful case studies showing how they are used and identified in ancient rocks, for example. One case study addresses the controversial finding of traces of fossil life in a meteorite from Mars. The book will be of interest not only to astrobiologists but also to terrestrial paleontologists as well as any reader interested in the prospects of finding a second example of life on another planet.Digital Technology for Forensic Footwear Analysis and Vertebrate Ichnology
Par Matthew Bennett, Marcin Budka. 2019
“There is no branch of detective science which is so important and so much neglected as the art of tracing…
footsteps. Happily, I have always laid great stress upon it, and much practice has made it second nature to me.” Sherlock Holmes, Study of Scarlet.Despite the fictional nature of Sherlock Holmes this statement rings true today. The study of footwear is neglected in modern forensic practice and does have much to offer. What it needs is an injection of technology and modern analytical tools. These tools are emerging from the digital revolution currently transforming vertebrate ichnology. Ichnology is the discipline of earth science which focuses on the study of trace fossils such as footprints. This book draws upon both disciplines - geology (ichnology) and forensic science - to show how the two have much to learn from each other especially with regard to the digital capture and analysis of footprints. This book presents field and laboratory methods associated with the collection, analysis and presentation of three-dimensional tracks (footprints) whether from a crime scene or a geological/archaeological excavation. It shows students, researchers and practitioners how to collect and analyse 3D data and take advantage of the digital revolution transforming ichnology. This book is not only essential reading for forensic and earth science students but also for professional forensic practitioners as well as for applied computer scientists developing new tools for visualization and analysis of 3D data. The book forms a natural methods focused complement to the successful text Fossilised Locomotion published by Springer 2014.Deep Time Analysis: A Coherent View Of The History Of Life (Springer Geology Ser.)
Par Mark A S McMenamin. 2018
Using a series of case studies, the book demonstrates the power of dynamic analysis as applied to the fossil record.…
The book considers how we think about certain types of paleontological questions and shows how to answer them. The analytical tools presented here will have wide application to other fields of knowledge; as such the book represents a major contribution to the deployment of modern scientific method as it builds on author's previous book, Dynamic Paleontology. Students and seasoned professionals alike will find this book to be of great utility for refining their approach to their ongoing and future research projects.Noah's Ravens: Interpreting the Makers of Tridactyl Dinosaur Footprints (Life of the Past)
Par James Farlow. 2018
How can the tracks of dinosaurs best be interpreted and used to reconstruct them? In many Mesozoic sedimentary rock formations,…
fossilized footprints of bipedal, three-toed (tridactyl) dinosaurs are preserved in huge numbers, often with few or no skeletons. Such tracks sometimes provide the only clues to the former presence of dinosaurs, but their interpretation can be challenging: How different in size and shape can footprints be and yet have been made by the same kind of dinosaur? How similar can they be and yet have been made by different kinds of dinosaurs? To what extent can tridactyl dinosaur footprints serve as proxies for the biodiversity of their makers? Profusely illustrated and meticulously researched, Noah’s Ravens quantitatively explores a variety of approaches to interpreting the tracks, carefully examining within-species and across-species variability in foot and footprint shape in nonavian dinosaurs and their close living relatives. The results help decipher one of the world’s most important assemblages of fossil dinosaur tracks, found in sedimentary rocks deposited in ancient rift valleys of eastern North America. Those often beautifully preserved tracks were among the first studied by paleontologists, and they were initially interpreted as having been made by big birds—one of which was jokingly identified as Noah’s legendary raven.Orthogenesis versus Darwinism
Par Igor Popov. 2018
This book reviews the convoluted history of orthogenesis with an emphasis of non-English sources, untangles relationships between various concepts of…
directed evolution and argues whether orthogenesis has something to offer modern biology. Darwinism claims that evolution occurs by selection from an extensive random variability. An alternative viewpoint—that the material for variability is limited and organisms are predisposed to vary in certain directions—is the essence of evolutionary concepts that can be grouped together under the name of orthogenesis. Dating back to Lamarck, orthogenesis has existed in many guises. Branded as mystical and discarded as unscientific, it keeps re-emerging in evolutionary discussions.End of the Megafauna: The Fate Of The World's Hugest, Fiercest, And Strangest Animals
Par Peter Schouten, Ross D MacPhee. 2019
The fascinating lives and puzzling demise of some of the largest animals on earth. Until a few thousand years ago,…
creatures that could have been from a sci-fi thriller—including gorilla-sized lemurs, 500-pound birds, and crocodiles that weighed a ton or more—roamed the earth. These great beasts, or “megafauna,” lived on every habitable continent and on many islands. With a handful of exceptions, all are now gone. What caused the disappearance of these prehistoric behemoths? No one event can be pinpointed as a specific cause, but several factors may have played a role. Paleomammalogist Ross D. E. MacPhee explores them all, examining the leading extinction theories, weighing the evidence, and presenting his own conclusions. He shows how theories of human overhunting and catastrophic climate change fail to account for critical features of these extinctions, and how new thinking is needed to elucidate these mysterious losses. Along the way, we learn how time is determined in earth history; how DNA is used to explain the genomics and phylogenetic history of megafauna—and how synthetic biology and genetic engineering may be able to reintroduce these giants of the past. Until then, gorgeous four-color illustrations by Peter Schouten re-create these megabeasts here in vivid detail.This book takes a non-technical approach in covering the evolution of South American mammalian fauna throughout geological history, and discusses…
how South America has changed due to mammalian invasions. Unlike other works on the subject, this book attempts to answer several crucial questions that often go unmentioned together in one cohesive monograph. What was the fauna like before the American interchange? What were the origins of the now-extinct groups when northern species arrived and out-competed them? How did the modern mammalian fauna come into being with such disparate animal groups? This information is given from a historical perspective throughout the book's 15 chapters, and is presented in an easily graspable fashion by mostly avoiding technical language. The book is written for academics, scientists and scholars engaged in paleontology, zoology and evolutionary biology, but may also appeal to a larger audience of general readers interested in mammalian evolution. The book begins with an introduction, describing the tools necessary to interpret the evolutionary history of South American mammals in geological terms and some of the early people who helped found South American mammalian paleontology. Chapter 2 describes the Mesozoic first mammals of Gondwana and what we are learning about them, dominant before the K/T extinction event. Then chapters 3 through 8 cover the Cenozoic, or "Age of Mammals", highlighting the major mammalian groups of South America that replaced the earlier mammals of Gondwana. These groups include the marsupials, native ungulates, the xenarthrans (armadillos, anteaters, sloths), the caviomorphs (rodents), and the platyrrhine monkeys. Chapters 9 and 10 address the Antarctic La Meseta fossils and the Colombian La Venta fossil faunal assemblages. Chapter 11 discusses the neotropical mammals that invaded the Caribbean Islands, and illustrates the influence South America has had on adjacent faunas. Chapter 12 describes the origin of the Amazon River and the role it has played in the evolution of the mammals and other flora and fauna. Chapter 13 tells the story of the Great American Biotic Interchange (GABI), and chapter 14 follows this up with a discussion of the Pleistocene mammal communities and their eventual extinction. Chapter 15 concludes the text by discussing the modern mammals of South America, and how despite the extensive Pleistocene extinctions there is still a lot of mammalian diversity in South America.The Dinosaur Artist: Obsession, Betrayal, and the Quest for Earth's Ultimate Trophy
Par Paige Williams. 2018
In 2012, a New York auction catalogue boasted an unusual offering: "a superb Tyrannosaurus skeleton." In fact, Lot 49135 consisted…
of a nearly complete T. bataar, a close cousin to the most famous animal that ever lived. The fossils now on display in a Manhattan event space had been unearthed in Mongolia, more than 6,000 miles away. At eight-feet high and 24 feet long, the specimen was spectacular, and when the gavel sounded the winning bid was over $1 million. Eric Prokopi, a thirty-eight-year-old Floridian, was the man who had brought this extraordinary skeleton to market. A onetime swimmer who spent his teenage years diving for shark teeth, Prokopi's singular obsession with fossils fueled a thriving business hunting, preparing, and selling specimens, to clients ranging from natural history museums to avid private collectors like actor Leonardo DiCaprio. But there was a problem. This time, facing financial strain, had Prokopi gone too far? As the T. bataar went to auction, a network of paleontologists alerted the government of Mongolia to the eye-catching lot. As an international custody battle ensued, Prokopi watched as his own world unraveled. In the tradition of The Orchid Thief, The Dinosaur Artist is a stunning work of narrative journalism about humans' relationship with natural history and a seemingly intractable conflict between science and commerce. A story that stretches from Florida's Land O' Lakes to the Gobi Desert, The Dinosaur Artist illuminates the history of fossil collecting--a murky, sometimes risky business, populated by eccentrics and obsessives, where the lines between poacher and hunter, collector and smuggler, enthusiast and opportunist, can easily blur. In her first book, Paige Williams has given readers an irresistible story that spans continents, cultures, and millennia as she examines the question of who, ultimately, owns the past.Click and Jane: Dinosaur Hunters
