This book was released on 2016-11-29 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darriwilian to Sandbian (Ordovician) Graptolites from Northwest China analyzes the significance of these exquisite, mostly pyritic, graptolites of the middle to late Ordovician period from North China and Tarim, China—locations that have developed the world's most complete successions of strata and fossil records. The book provides the first systematic account of the renowned graptolite faunas, with over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone, also presenting a comprehensive accounting of the graptolites during the critical transition from the middle to late Ordovician period with important data on new morphologies, the latest conventions in classification, diversity change and evolution, refined biostratigraphy divisions, and correlation with other major regions or continents. The book provides a key resource for paleontologists, stratigraphic specialists, petroleum geologists, and graduate students in varying fields of geology. - Presents the first systematic accounting of these world-renowned graptolite fauna - Provides an ideal reference for those interested in rocks, fossils, and biostratigraphy - Presents over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone - Includes research from the top, most influential, Ordovician graptolite and conodont paleontologists in the world - Generously illustrated with four-color figures and photos throughout

Download or read book A Global Synthesis of the Ordovician System Part 1 written by D.A.T. Harper and published by Geological Society of London Special Publications. This book was released on 2023-06-07 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.
