The 'Hettangian' is the first
stage of the
Early Jurassic Epoch. It spans the time between 199.6 ± 0.6
Ma and 196.5 ± 1 Ma (million years ago). The stage follows the
Rhaetian Stage of the
Triassic Period.
The stage takes its name from
Hettange-Grande, a town in northern
France, just south of the border with
Luxembourg on the main road from
Luxembourg City to
Metz.
In Europe this period, together with the
Sinemurian, is also known as the '
Lower (or Blue) Lias Stage'.
