At least one newsletter was produced almost every year from when the subcommission started in 1978 until 2010. These newsletters report on research related to the recognition of GSSPs, and any other science relevant to the Jurassic. From 2010 this information has been published in Volumina Jurassica instead.

The ISJS Newsletters that were published from 1978 to 2010 are available for download below. We are particularly grateful to Eckhard Mönnig, Naturkunde-Museum, Coburg, Germany who has spent many hours expertly digitising all of these newsletters.

New contributions: Please send any new material for publication in the year ahead to both the Chair of ISJS and through the manuscript submission route for Volumina Jurassica following the instructions for authors.
