Download or read book Stratigraphy Around the Permian–Triassic Boundary of South China written by Wei-hong He and published by Springer Nature. This book was released on 2024-01-16 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book timely provides high-quality records of 32 PTB sections across different depositional settings from terrestrial to marine facies in South China, including descriptions of lithologies, high-resolution correlation of key boundaries and fossil occurrences at each section. This book also analyzes the patterns and processes of the community and ecosystem evolution over space and through time in the lead to the end-Permian mass extinction, and critically analyzes the mostly debated hypothesis, anoxia and volcanism, which were considered as the causes of mass extinction, based on the data from the studied sections of South China, together with materials from other regions of the world.

Download or read book The Triassic Timescale written by Spencer G. Lucas and published by Geological Society of London. This book was released on 2010 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mesozoic Era begins with the approximately 50-million-year-long Triassic Period, a major juncture in Earth history when the vast Pangaean supercontinent completed its assembly and began its fragmentation, and the global biota diversified and modern-ized after the end-Permian mass extinction, the most extensive biotic decimation of the Phanerozoic. The temporal ordering of geological and biotic events during Triassic time thus is critical to the interpretation of some unique and pivotal events in Earth his-tory. This temporal ordering is mostly based on the Triassic time-scale, which has been developed and refined for nearly two centu-ries. This book reviews the state of the art of the Triassic timescale and includes comprehensive analyses of Triassic radio-isotopic ages, magnetostratigraphy, isotope-based and cyclostratigraphic correlations and timescale -relevant marine and non-marine bio-stratigraphy.

Download or read book Paleontology and Neontology of Cephalopods written by M. R. Clarke and published by Elsevier. This book was released on 2013-10-22 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleontology and Neontology of Cephalopods examines information that throws new light on the evolution of coleoids. This book is part of a multivolume work, The Mollusca, which attempts to provide comprehensive treatment of major areas of molluscan research. The Mollusca is intended to serve several disciplines—zoology, biochemistry, physiology, and paleontology. It will prove useful to researchers and to all others with interests in mollusks. The book begins with a review of the main features of cephalopod evolution. This is followed by separate chapters on the evolution of the gladius in coleoids; the buccal mass of Cephalopoda; beaks of living coleoid Cephalopoda; cephalopod hooks; statoliths of cephalopods; buoyancy and locomotion in recent cephalopods; and evolution of the cephalopod brain and cephalopod statocyst. Subsequent chapters deal with the photophore structure and evolution within the Enoploteuthinae; the interrelationships of genera within the Ommastrephidae; evolutionary pathways traversed by the cephalopod family Cranchiidae; the cephalopod fauna of the European Mediterranean; and the evolution of recent cephalopods.

Download or read book Morphogenesis, Environmental Stress and Reverse Evolution written by Jean Guex and published by Springer Nature. This book was released on 2020-07-23 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution. Capacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of ‘reverse evolution’ by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.

Download or read book Permian-Triassic Evolution of Tethys and Western Circum-Pacific written by Yin Yin Hongfu and published by Elsevier. This book was released on 2000-05-10 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Permian and Triassic are the interval known for the integration and separation of Pangea, the closure of the Palaeotethys and the opening of Mesotethys. They were associated with a series of worldwide events including the Late Palaeozoic glaciation and succeeding extensive evaporatic and reef formations, the end-Palaeozoic regression, strong orogenies and widespread volcanism and magmatism, and finally, the Permo-Triassic biotic macro-extinction. These events resulted in the formation of enormous reserves of coal, petroleum, evaporites, phosphorites and metal resources. The Permian and Triassic thus constitutes a time interval particularly important both for understanding the Earth's history and for exploration of mineral resources.The book aims to reconstruct the Permian-Triassic history of Pangea, Palaeo-Tethys and Palaeo-Pacific through stratigraphic, palaeogeographic and other interdisciplinary approaches. It consists of two parts. Part 1 deals with regional stratigraphy of Tethyan and western Circum-Pacific countries which is the basis for interregional correlation, and palaeogeography. Part 2 deals with the biotic evolution at the Permian-Triassic transition, focusing on the major invertebrate groups: foraminifers, radiolarians, brachiopods, ammonoids and conodonts.
