For the Jurassic period, ammonites remain the most precise biostratigraphic tool from inter-regional, inter-bioprovincial, and global time correlations. In this book, foremost Soviet authorities discuss regional ammonite associations and their successions. They devise regional ammonite range zones, assemblage zones, and even standard zones which they then time-correlate with the international standard time scale constructed in western Europe. This is a completely revised and emended translation of the 1982 Russian-language work Jurassic Zones of the U.S.S.R., with the important addition of illustrations of index and guide ammonites for the Soviet Union.
