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.

Lanzhou, Gansu, China Notable for its "astonishingly huge teeth", among the largest for any herbivorous creature ever, which indicate it is an iguanodont. The mandible, longer than one meter, suggests very large size for the animal.
