Réserve naturelle nationale du Toarcien: Protected Jurassic Stratotype and Geological Map
A vital paleontological heritage site in the Nouvelle-Aquitaine region
As the smallest national nature reserve in France, Réserve naturelle nationale du Toarcien provides a concentrated, scientifically essential view of Jurassic marine sediments. The protected quarries preserve ammonite-rich strata and complex geological unconformities, serving as the international definition for the Toarcian geological stage within the Thouet valley landscape.
