Request for Information for 2019 Annual Report

Hello IGCP 653 participants,

The fourth year of our project has been both an excellent and productive year. Our members had the opportunity to present and learn about cutting edge science at IGCP 653 sponsored meetings, network, develop new collaborations, and publish new findings related to the onset of the Great Ordovician Biodiversification Event.

It is time already to compile our fourth annual report. Throughout the year, we have compiled a partial list of publications associated with our project here:
However, recognize this list in highly incomplete, and we need to fully document the project publication output for the annual report.  

Thus, please email Christian Mac Ørum Rasmussen ( a list of any publications resulting from IGCP 653 efforts in which you have cited the project in the acknowledgements section by December 1st. If you have project related publications, that did not explicitly cite the project, we would also appreciate a list of those.

Also, please do remember to prepare your future papers with acknowledgements to our project with a sentence such as “This paper is a contribution to the International Geoscience Programme (IGCP) Project 653 – The onset of the Great Ordovician Biodiversification Event.”

We are looking forward to another highly productive year in 2020 with the Main Annual (and Closing) meeting in Copenhagen, Denmark in June 2020. The technical sessions are fixed and scheduled for the period 8-12 of June. Geological excursions will be organized as pre- and post-congress field-trips.  The first circular will be in your mailbox soon.

There will also be a regional meeting in North China, including a ceremony at the new ASSP for the basis of the Ordovician System at Dayangcha from May 14-16, 2020. 

Please email Thomas Servais ( with sponsorship proposals for additional meetings or symposia.

Thanks and best wishes,

IGCP 653 co-leaders
