Valanginian |
In the geologic timescale, Valanginian is a stage of the Early Cretaceous epoch. It spanned between 140.2 ± 3.0 Ma and 136.4 ± 2.0 Ma (million years ago). The Valanginian stage succeeds the Berriasian stage of the Early Cretaceous and precedes the Hauterivian stage of the Early Cretaceous. It is named after Valangin, a small town north of Neuchâtel in the Jura Mountains of Switzerland.
