In this work, sixty specialists assembled to discuss the regional occurrences of Jurassic rocks around the Pacific rim. The tectonic setting, stratigraphical sequences, and fossil assemblages of the region 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 intercontinental circum-Pacific correlations, and a large atlas illustrates more than 1,000 circum-Pacific index fossils.
