Assemblage 8 (Devonian of France)

Also known as Upper part of the Patures member of the Beaulieu formation

Where: Boulonnais, France (46.0° N, 2.0° E: paleocoordinates 28.1° S, 21.1° E)

• coordinate estimated from map

When: Patures Member (Beaulieu Formation), Frasnian (382.7 - 372.2 Ma)

• approx. 10-12m thick

• member-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal, black claystone

• The sediments are represented by dark clays with rare calcareous quartziferous biomicritic nodules. These are overlain by black clays with more abundant calcareous nodules.
