Since the last newsletter the main 1998 meeting was held in Warsaw, Poland. IGCP 406 was also represented t at the Silurian Subcommission meeting in Spain (Märss), the ECOS VII (conodont) meeting in Italy (see report below), and SVP meetings in U.S.A. Several smaller workshops, field meetings, and field trips (funded by other agencies) were also held by project participants.

IGCP 406 Annual Meeting: Circum-Arctic Palaeozoic Faunas and Facies Geological Institute, Warsaw University, Warsaw, Poland, Sept. 3-8 1998 including Timan- Pechora and Chondrichthyan workshops.

Was hosted by Instytut Geologii Podstawowej, Wydzia Geologii, Uniwersytet Warszawski (Institute of Geology, Faculty of Geology, Warsaw University); Meeting Organisers were Michal Ginter, Stan Skompski and B. Sobociñska.
