This is the homepage of the Subcommission on Ordovician Stratigraphy (SOS). The Ordovician community is a dynamic, international group of scientists investigating all aspects of the Earth system during the Ordovician Period. Our community gathers in both in traditional in-person meetings and through virtual conferences.
See the Conferences page for a list of upcoming events.
The annual Ordovician News provides an in-depth overview of the activities of members of our community and contact information to facilitate strengthing scientific connections. See the latest issue and the backlog on the Ordovician News page.
