Download or read book Southern Hemisphere Palaeobiogeography of Triassic Jurassic Marine Bivalves written by Susana E. Damborenea and published by Springer Science & Business Media. This book was released on 2012-09-26 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeobiogeography is a complex subject which processes information provided by both Biology and Earth Sciences. It is conceptually and philosophically equivalent to neobiogeography. Nevertheless, its methods are somewhat different, since it is limited by the incompleteness of the fossil record. On the other hand, it has direct access to the time dimension, a key ingredient of organic evolution. Mesozoic benthonic mollusks, and especially bivalves, have a great potential for palaeobiogeographical analysis due to their commonly good preservation, abundance, diversity and high dispersion potential at the larval stage. From a merely descriptive point of view, the analysis of their distribution shows latitudinal gradients and distributional patterns, both at regional and global scales, which are the basis for the recognition of biochoremas or palaeobiogeographical units of different ranks. Moving forward towards a causal palaeobiogeography, these organisms also provide interesting insight into particular biogeographical questions, such as bipolarity and its origin. The evolution in time of the recognized biochoremas can be discussed in relation to palaeoclimas and extinction events. Finally, some of the results obtained from the analysis of the distribution of past bivalve biotas were even used to propose and discuss the development of marine corridors and argue about the distribution of continents in the past.

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.

This book was released on 2005-09-15 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, 60 specialists come together to discuss the regional occurrences of Jurassic rocks. Not only is this the first comprehensive synthesis of Jurassic geology and palaeontology, but it is in fact the only one of its kind for any geological system.

Download or read book Jurassic Rhynchonellids written by Xiao-ying Shi and published by . This book was released on 1993 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jurassic brachiopods of the order Rhynchonellida are classified according to modern concepts and techniques, with special attention to internal structures. They are grouped into 6 families and 16 subfamilies of which three are new: the Acanthorhynchiinae, the Cryptorhynchiinae, and the Piarorhynchiinae. Subfamilies emended or revised are the Acanthothyridinae Schuchert (1913) raised to family rank, Davanirhynchinae Ovtsharenko (1983), Dzhangirhynchinae Ovtsharenko (1983), Erymnariinae Cooper (1959), Indorhynchiinae Ovtsharenko (1975), Septocrurellinae Ager, Childs, and Pearson (1972), and Striirhynchiinae Kamyshan (1968). New genera are Aalenirhynchia (type-species Rhynchonella subdecorata Davidson, 1853), Bradfordirhynchia (type-species Cryptorhynchia bradfordensis Buckman, 1918), and Sharpirhynchia (type-species Kallirhynchia sharpi Muir-Wood, 1938). A new subgenus is Burmirhynchia (Hopkinsirhynchia) (type-species Burmirhynchia hopkinsi Davidson, 1854). The only new species is Pycnoria depressa. Eleven genera are revised, and many are transferred among the subfamilies; lectotypes are designated where needed.
