The International Subcommission on Jurassic Stratigraphy (ISJS) comprises an international group of scientists from universities, geological surveys, research organisations, industry and museums who conduct scientific research on strata of Jurassic age (c. 201 – 143 million years ago). In order to advance the global understanding of the Jurassic, we specialise in combining expertise and local Jurassic geological knowledge from across the world in an open and collaborative manner.
We are an official body of the International Commission on Stratigraphy (ICS) and of the International Union of Geological Sciences (IUGS). Each year we report to ICS, which in turn reports to IUGS. We have an official membership that comprises four officers (Chair, two Vice-Chairs, Secretary) and twenty additional Voting Members. In addition, we have an unspecified number of Corresponding Members. As a worldwide association ISJS welcomes anyone who has a professional or scholarly interest in the geology of the Jurassic.
The main aims of the ISJS are:
