The Sinemurian is a stage of the
Early JurassicEpoch. It spans the time between 196.5 ± 2 Ma and 189.6 ± 1.5 Ma (million years ago).
The stage takes its name from the town of Semur-en-Brionnais, near
Sancerrein the upper Loire Valley. The calcareoussoil formed from the Jurassic limestoneof the region is in part responsible for the character of the classic Sancerre wines.
In Europe this period, together with the
Hettangian, is also known as the Lower (or Blue) Lias Stage.
