Available in PDF, EPUB and Kindle. Book excerpt: Graptolites lived in the earth's oceans from 540 million years ago to 320 million years ago, when they became extinct. For most of that time they dominated the upper layers of the ocean in tropical regions as the earth's first large zooplankton. They varied from a few millimetres in length to more than a metre; they lived by the countless billion, and their skeletons are preserved today in vast numbers in varied strata in every continent except Antarctica. Because of their diversity, they are a powerful correlative tool: units of time of much less than a million years are identifiable, and within individual rock sequences evolutionary changes can be studied, which makes them of prime importance to economic geologists. Graptolites are, however, still the subject of lively debate — little is established about their lives, and although skeletons abound, the soft parts of only one graptolite have been found — in deposits 500 million years old in Tasmania. As well as providing a full summary of the current state of knowledge relating to graptolites, the team of specialists who contribute to this book also address the biological questions raised by these fossils, and provide pointers for further research. Contents: Part I. The Organism: Definition and appearance; Preservation; Construction; Distribution; Biology; Evolution; Relationship to other organisms; Sex life. Part II. The Fossil: Collection and preparation; Identification; Correlative uses. Appendices: Glossary of technical terms; Where to find them in Britain and other countries; Classification and evolution; Further reading.BARRIE RICKARDS is Reader in Palaeobiology, University of Cambridge, and curator of the Sedgwick Museum of Geology.

Book Synopsis Graptolite Paleobiology by : Jörg Maletz
Download or read book Graptolite Paleobiology written by Jörg Maletz and published by John Wiley & Sons. This book was released on 2017-05-08 with total page 299 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.
