These Projects are independent of [email protected] the Jurassic Subcommission but the Jurassic Subcommission maintains links with two IGCP Last Year – Next Year. Another year gone – how Projects: time flies! The past year (2005-2006) was certainly eventful, with a number of important meetings, Project 458: Triassic-Jurassic Boundary Events has including the “last” of IGCP Project 458, the first of contributed an enormous amount of important data on IGCP Project 506, field and discussion meeting of the correlation around the Triassic/Jurassic boundary (though Toarcian Working Group in Peniche (Portugal) and a this is not its sole objective), which is proving of great joint field and discussion meeting of the Kimmeridgian value to the Triassic/Jurassic Boundary Working Group. and Tithonian Working Groups (WGs) in Stuttgart Unfortunately, this Project formally ended in 2005 but (Germany). These meetings, plus all the smaller there will be a Joint Special Session during the Krakow meetings and a lot of hard work by individuals, are Congress. contributing significant data and results to research on the Jurassic. On behalf of all the “members and friends” Project 506: Marine and Non-marine Jurassic of the Jurassic I express my sincere thanks. Correlation was approved to start in 2005 and is expected to run until 2009. The first meeting – a The next year (2006-2007) is the most important in the Symposium on Jurassic Boundary Events – was held in four-year cycle of activities with which the Jurassic Nanjing, China in November 2005. The second meeting Subcommission is associated. It brings the 7th is a Topical Symposium on Marine and non-marine International Congress on the Jurassic System during Jurassic: biodiversity and ecosystems during the 2nd which the fruits of all the work mentioned above will be International Palaeontological Congress in Beijing, presented. We owe a great debt of gratitude to our Polish China, in June 2006, followed by post-Congress field colleagues under the Chairmanship of Andrzej excursion C7 Terrestrial Triassic-Jurassic sequence and Wierzbowski, for their dedication to the organisation of biota in the Junggar Basin, Xinjiang. The third meeting this event. Those of you who have not been involved in will be a Special Session during the Jurassic Congress organising such an occasion cannot imagine just how in Krakow. much is involved! This is an especially important Congress because it comes at a critical time in the IUGS Revue of the International Commission Subcommission’s priority project of the selection and on Stratigraphy. The International Commission on proposal of GSSPs for the remaining Jurassic Stages. Stratigraphy is the largest of the Commissions within This will be an important topic for the Congress. the International Union of Geological Sciences and has been in existence for a long time. In 2005 the IUGS Global Stratotypes. The priority in stratigraphical Executive decided to establish an Ad-hoc Review research for IUGS, its International Commission on Committee, under the Chairmanship of Alberto Stratigraphy and the various System-related Riccardi, to review the ICS. [John Callomon was one of Subcommissions, remains completion of definition of the Committee members.] The committee convened in the units of the International Stratigraphic Chart by the Paris on 7 th-8th November 2005. establishment of a Global Stratotype Section and Point (GSSP) for the basal boundary of each In June 2006 the Executive Committee of IUGS chronostratigraphic unit down to Stage level in the announced that it approved the Review Committee hierarchy. Some of the Subcommissions (e.g., report and “is pleased to congratulate ICS for the Devonian, Silurian) completed these in the 1980s and important work it has done in promoting stratigraphic are either having to revise these or are defining research, as the establishment of GSSPs has produced an Substages; others are making slow progress.

For three others (Toarcian, Callovian, Kimmeridgian) it seems that the preferred candidate section has been Among 11 additional recommendations to ICS: selected and a formal proposal to the Subcommission (i) Typological definitions of standard chronostratigraph- can be expected in late 2006 or early 2007.

There has not yet been time for discussion within ICS, The Jurassic/Cretaceous boundary is technically the so any comments and suggestions would be welcome responsibility of the Cretaceous Subcommission, but and can be passed on to ICS for consideration. progress on in documentation and selection for this boundary is disappointingly slow.

The larger so that a “world-wide web” of Correspondents is presentations will be grouped in 9 sessions (two of them available. To make this feasible, a Directory is devoted to IGCP projects – no. 458 “Triassic-Jurassic distributed to all members, but for this to be fully boundary events”, and no. 506 “Marine and non-marine effective it must be kept up to date. It is, therefore, Jurassic: global correlations and major geological extremely important that you inform the members of the events”). The contributions will be published in the Executive (myself, Paul Bown and Paul Smith) of any Congress Volume (the manuscripts to be submitted change of address, especially of email address. during the Congress).
