Invertebrate Palaeontology and Evolution is well establishedas the foremost palaeontology text at the undergraduate level. Thisfully revised fourth edition includes a complete update of thesections on evolution and the fossil record, and the evolution ofthe early metazoans. New work on the classification of the major phyla (inparticular brachiopods and molluscs) has been incorporated. The section on trace fossils is extensively rewritten. The author has taken care to involve specialists in the majorgroups, to ensure the taxonomy is as up-to-date and accurate aspossible.

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)

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
