The International Subcommission on Jurassic Stratigraphy
The International Subcommission on Jurassic Stratigraphy (ISJS) is an official body of the International Commission on Stratigraphy (ICS, of which the various Subcommission chairs are voting members) and of the International Union of Geological Sciences (IUGS). Each year we report to ICS, which reports in turn to IUGS. In this role we have three officers (Chairman, Vice-Chairman, Secretary) and twenty Voting Members, with, in addition, an unspecified number of Corresponding Members. Additionally, the ISJS is a worldwide association of all those who have an interest in the geology of the Jurassic, whether or not they are 'official' members.
The main aims of the ISJS are:
1. To promote and coordinate long-term international cooperation and establish standards in stratigraphy, with the priority to define global chronostratigraphic units.
2. To enable and promote international collaboration in research on the Jurassic and to sponsor regular international meetings.
