This book was released on 1986 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mestognathus, an important Early Carboniferous conodont genus whose appearance has generally been thought to coincide with, and define, the base of the Visean, evolved from Clydagnathus during the Tournaisian and ranges from that stage into the Namurian. Five species, including M. harmalai sp. nov. and M. praebeckmanni sp. nov. , are distinguished by the gradual phyletic development of the parapet, the fixed blade, the anterior notch, the position of the carinal deflection, and the increasing tendency to evert the basal cavity. Mestognathus dhuensis and M. neddensis are demonstrated to be synonyms of M. beckmanni, M. bipluti, or Mestognathus spp.

Book Synopsis The Carboniferous Timescale by : S.G. Lucas
Download or read book The Carboniferous Timescale written by S.G. Lucas and published by Geological Society of London. This book was released on 2022-04-26 with total page 1012 pages. Available in PDF, EPUB and Kindle. Book excerpt: The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.
Book Synopsis Faunal and Floral Migration and Evolution in SE Asia-Australasia by : Ian Metcalfe
Download or read book Faunal and Floral Migration and Evolution in SE Asia-Australasia written by Ian Metcalfe and published by CRC Press. This book was released on 2001-06-01 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multidisciplinary book focuses on the relationships and interactions between palaeobiogeography, biogeography, dispersal, vicariance, migrations and evolution of organisms in the SE Asia-Australasian region. The book investigates biogeographic links between SE Asia and Australasia which go back more than 500 million years. It also focuses on the links between geological evolution and biological migrations and evolution in the region. It was in the SE Asian region that Alfred Russell Wallace established his biogeographic line, now known as Wallace's Line, which was the beginning of biogeography. Wallace also independently developed his theory of evolution based on his work in this area.;The book brings together, for the first time, geologists, palaeontologists, zoologists, botanists, entomologists, evolutionary biologists and archaeologists, in the one volume, to relate the region's geological past to its present biological peculiarities. The book is organized into six sections. Section 1 Paleobiogeographic Background provides overviews of the geological and tectonic evolution of SE Asia-Australasia, and changing patterns of land and sea for the last 540 million years. Section 2 Palaeozoic and Mesozoic Geology and Biogeography discusses Palaeozoic and Mesozoic biogeography of conodonts, brachiopods, plants, dinosaurs and radiolarians and the recognition of ancient biogeographic boundaries or Wallace Lines in the region. Section 3 Wallace's Line focuses on the biogeographic boundary established by Wallace, including the history of its establishment, its significance to biogeography in general and its applicability in the context of modern biogeography.;Section 4 Plant biogeography and evolution includes discussion on primitive angiosperms, the diaspora of the southern rushes, and environmental, climatic and evolutionary implications of plants and palynomorphs in the region. The biogeography and migration of insects, butterflies, birds, rodents and other non-primate mammals is discussed in section 5, Non Primates. The final section 6 Primates focuses on the biogeographic radiation, migration and evolution of primates and includes papers on the occurrence and migration of early hominids and the requirements for human colonization of Australia.

Book Synopsis Proceedings of the XVth International Congress on Carboniferous and Permian Stratigraphy by : Theo Edward Wong
Download or read book Proceedings of the XVth International Congress on Carboniferous and Permian Stratigraphy written by Theo Edward Wong and published by Edita-The Publishing House of the Royal. This book was released on 2007 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compendium of papers first presented at the fifteenth annual International Congress on Carboniferous and Permian Stratigraphy, this book offers an overview of the latest research on rock formation that took place over 250 million years ago. This ancient sediment, which provides much of the mineral resources we use today, is a key indicator of massive environmental shifts that occurred around the creation of the super-continent Pangea. Organized thematically, the book covers a wide variety of topics, including the structural development of Carboniferous basins, the paleontology of those periods, and Carboniferous and Permian timescales and global correlations. As the contributors demonstrate, a better understanding of the evolution of the earth during the Carboniferous and Permian periods will not only help us find more mineral resources, but will also provide insight into important modern environmental questions.

Book Synopsis Conodonts of the Lower Border Group and Equivalent Strata (Lower Carboniferous) in Northern Cumbria and the Scottish Borders, U.K. by : Mark A. Purnell
Download or read book Conodonts of the Lower Border Group and Equivalent Strata (Lower Carboniferous) in Northern Cumbria and the Scottish Borders, U.K. written by Mark A. Purnell and published by . This book was released on 1992 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The shallow-shelf carbonates of the Lower Border group and equivalent strata of the Northumberland trough have yielded conodont elements belonging to 28 multielement species. Study of these cavusgnathid-dominated faunas highlights the need for major revision of the Cavusgnathidae. Cloghergnatus globenskii Austin is an ecophenotype of Taphrognathus varians Branson and Mehl; Cloghergnathus Austin is ajunior synonym of Taphrognathus Branson and Mehl, Capricornognathus Austin appears to be a junior synonym of Patrognathus Rhodes, Austin, and Druce. The appartuses of Cavusgnathus hudsoni (Metcalfe), Taphrognathus varians, Polygnathus mehli Thompson, and Apatognathus cuspidatus Varker are described for the first time. Patrognathus capricornis (Druce), Mestognathus beckmanni Bischoff, Polygnathus bischoffi Rhodes, Austin, and Druce, and "Apatognathus" sp. a are partially reconstructed. The assignment of C. hudsoni to Cavusgnathus extends the range of the genus into the Tournaisian Series in Britain.

Book Synopsis Silurian Trilobites from the Northern Yukon Territory by : Rolf Ludvigsen
Download or read book Silurian Trilobites from the Northern Yukon Territory written by Rolf Ludvigsen and published by Royal Ontario Museum, 1990. c1989.. This book was released on 1990 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silurian trilobites are described from two contrasting facies in the northern Yukon Territory: basinal sediments of the Road River Formation at Prongs Creek and shallow-water limestones of the Illtyd Range. An Otarion Association from dark grey, argillaceous lime mudstones (Lower Silurian) consists of Kosovopeltis, Otarion (Songkania), Cromus, and Leonaspis. These trilobites are identical to those described by Pousen (1934) from his Cape Schuchert Formation of North Greenland. A Stenopareia Association from off-white biosparites (Lower Silurian) includes Stenopareia, a bumastine, Kosovopeltis, and Scotoharpes. A Hedstroemia Association occurs in an Upper Silurian debris flow. It includes Hedstoemia, Prantlia, Balizoma, and Paracybantyx. An incomplete ontogeny of Kosovopeltis borealis (Poulsen) comprises a protaspis and four different transitory pygidia. The bumastine genus Paracybantyx is new. New species are Paracybantyx asulcatus, Stenopareia illtyd, Hedstroemia kutchini, H. sourdoughi, and Prantlia vagrans.
