Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. During the 46-million-year Ordovician Period (489–443 m.y.), a bewildering array of adaptive radiations of "Paleozoic- and Modern-type" biotas appeared in marine habitats, the first animals (arthropods) walked on land, and the first non-vascular bryophyte-like plants (based on their cryptospore record) colonized terrestrial areas with damp environments. This book represents a compilation by a large team of Ordovician specialists from around the world, who have enthusiastically cooperated to produce this first globally orientated, internationally sponsored IGCP (International Geological Correlation Program) project on Ordovician biotas. The major part is an assembly of genus- and species-level diversity data for the many Ordovician fossil groups. The book also presents an evaluation of how each group diversified through Ordovician time, with assessments of patterns of change and rates of origination and extinction. As such, it will become the standard work and data source for biotic studies on the Ordovician Period.

A volume from a monograph series featuring seven papers on trilobites with brief summaries This research volume is entitled Papers from the 6th International Conference on Trilobites and their Relatives. It's Volume 64 within the Fossils and Strata monograph series. The research compilation originated from a 2017 conference in Estonia. Seven papers on trilobites are included with summaries in the publication. The papers' topics cover trilobites from the Early Cambrian to the Late Devonian.

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
