Faluns Sea (original) (raw)

The Faluns Sea is a former sea which covered Western France from 16 to 3.5 Ma. It spreads from Normandy to Vienne by forming an inlet through what is today Brittany, Anjou, Touraine and Blésois. After its withdrawal it left behind it a stone rich in fragmentary shells called falun. The sea got its name from this sedimentary rock known for being rich in fossils.
