Hettangien

The Hettangien is the stratigraphic first stage Jurassic lower (Lias). It extends from 199,6 ± 0,6 and 196,5 ± 1 million years and precedes the Sinémurien.

Its name comes from Hettange in the Moselle. A reserve located in a career at Hettange makes it possible to see the Stratotype of Hettangien.
