Download or read book Graptolite Paleobiology written by Jörg Maletz and published by John Wiley & Sons. This book was released on 2017-03-14 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The graptolites constitute one of the geologically most useful taxonomic groups of fossils for dating rock successions, understanding paleobiogeography and reconstructing plate tectonic configurations in the Lower Palaeozoic. Graptolites were largely planktic, marine organisms, and as one of the first groups that explored the expanses of the world’s oceans are vital for understanding Palaeozoic ecology. They are the best and often the only fossil group for dating Lower Palaeozoic rock successions precisely. Thousands of taxa have been described from all over the planet and are used for a wide variety of geological and palaeontological (biological) research topics. The recent recognition of the modern pterobranch Rhabdopleura as a living benthic graptolite enables a much better understanding and interpretation of the fossil Graptolithina. In the decades since the latest edition of the Graptolite Treatise, the enormous increase of knowledge on this group of organisms has never been synthesised in a compelling and coherent way, and information is scattered in scientific publications and difficult to sort through. This volume provides an up-to-date insight into research on graptolites. Such research has advanced considerably with the use of new methods of investigation and documentation. SEM investigation and research on ultrastructure of the tubaria has made it possible to compare extant and extinct taxa in much more detail. Cladistic interpretation of graptolite taxonomy and evolution has advanced the understanding of this group of organisms considerably in the last two decades, and has highlighted their importance in our understanding of evolutionary processes. This book will show graptolites, including their modern, living relatives, in a quite new and fascinating light, and will demonstrate the impact that the group has had on the evolution of the modern marine ecosystem. This book is aimed not only at earth scientists but also at biologists, ecologists and oceanographers. It is a readable and comprehensible volume for students at the MSc level, while remaining accessible to undergraduates and non-specialists seeking up-to-date information about this fascinating topic in palaeobiology.
Download or read book The Geology of England and Wales written by P. J. Brenchley and published by Geological Society of London. This book was released on 2006 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of 'The Geology of England and Wales' is considerably expanded from its predecessor, reflecting the increase in our knowledge of the region, and particularly of the offshore areas. Forty specialists have contributed to 18 chapters, which cover a time range from 700 million years ago to 200 million years into the future. A new format places all the chapters in approximately temporal order. Both offshore and economic geology now form an integral part of appropriate chapters.

Book excerpt: Distributed by Elsevier Science on behalf of Science Press. Biostratigraphic data are basic to geological and palaeontological research. This book presents up-to-date material and research achievements in biostratigraphy in recent decades in China, and provides a variety of knowledge to lay a solid foundation for geologists and palaeontologists worldwide. It consists of 13 chapters covering 13 major geological systems. Every chapter addresses tectonic sedimentary domains, current biostratigraphic systems, series boundaries, faunal/floral succession, evolutionary trends and bioevents, correlation of the standard columns in China with other part of the world, facies patterns, palaeobiogeography and palaeogeography. * Up-to-date and authoritative data basic to geologic research about China and all Asia * Concepts, procedures and classification follow modern international standards updated to the present * Written by leading Chinese geologists and palaeontologists
Download or read book The Geologic Time Scale 2012 written by Felix Gradstein and published by Elsevier. This book was released on 2012-09-01 with total page 1175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. - The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access - Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility - Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events - Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)
Download or read book The Planet in a Pebble written by Jan Zalasiewicz and published by OUP Oxford. This book was released on 2010-09-23 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of a single pebble. It is just a normal pebble, as you might pick up on holiday - on a beach in Wales, say. Its history, though, carries us into abyssal depths of time, and across the farthest reaches of space. This is a narrative of the Earth's long and dramatic history, as gleaned from a single pebble. It begins as the pebble-particles form amid unimaginable violence in distal realms of the Universe, in the Big Bang and in supernova explosions and continues amid the construction of the Solar System. Jan Zalasiewicz shows the almost incredible complexity present in such a small and apparently mundane object. Many events in the Earth's ancient past can be deciphered from a pebble: volcanic eruptions; the lives and deaths of extinct animals and plants; the alien nature of long-vanished oceans; and transformations deep underground, including the creations of fool's gold and of oil. Zalasiewicz demonstrates how geologists reach deep into the Earth's past by forensic analysis of even the tiniest amounts of mineral matter. Many stories are crammed into each and every pebble around us. It may be small, and ordinary, this pebble - but it is also an eloquent part of our Earth's extraordinary, never-ending story.

Book excerpt: يحكي هذا الكتاب قصة تاريخ الأرض السحيق، يتتبّع حياة حصاة ملقاة على شواطئ ويلز، حصاة عادية كغيرها من الحصى تجمع معظم ذرات عناصر الأرض. بدأت حياتها بظهور الكون بعد الإنفجار العظيم، وانتهى بها الأمر إلى الإستقرار على قيعان البحار والمحيطات القديمة. ومن هناك بدأت تخوض غمار الكثير من الأحداث، فتناولتها تحرّكات القشرة الأرضية، وتتابعت عليها أجيال من متعدّدات الخلايا، وتشكّل فيها الوقود العضوي، وتناوبت عليها العصور الجليدية، وضربتها الزلازل وأثرت فيها النيازك، بل إن أفعال البشر وقنابلهم النووية تركت أثرها عليها. والكتاب في كل ذلك يجمع علوماً شتّى يبني عليها ذلك التاريخ الطويل للأرض: من فيزياء الفلك، إلى حركة الصفائح، وعلوم المعادن، ودراسة المحيطات، وتحليل الأحافير - وهو الموضوع الذي استغرق الكثير من صفحاته - وعلوم أخرى متفرّعة عن تلك العلوم. ويمضي الكتاب إلى ما هو أبعد من دراسة التاريخ الماضي، فيحاول التنبؤ بمستقبل هذا الكوكب الجميل، وما ستؤول إليه صخوره وذرّاته عندما تذرى في فضاء الكون الفسيح.
