In this work, 60 specialists come together to discuss the regional occurrences of Jurassic rocks. The tectonic setting, stratigraphical sequences, and fossil assemblages of Jurassic rocks are covered in detail; regional biozones based on palynonorphs, protistans, plants and invertebrates are defined, and super-regional standard zones based on ammonites are established. Numerous tables are used to document and illustrate intra- and inter-continental circum-Pacific correlations, and a large atlas illustrates more than 1,000 circum-Pacific index and guide fossils. Resulting from International Geological Correlation Programme Project 171, not only is this the first comprehensive synthesis of Jurassic geology and palaeontology, but it is in fact the only one of its kind for any geological system. This book will prove indispensable to academic geologists, palaeontologists and stratigraphers interested in the Jurassic period.
