凡蓝今期(Valanginian)是白垩纪第二个时期，时间为140.2 ± 3.0 百万年前至 136.4 ± 2.0 百万年前。接续贝里亚期之后，豪特里维期之前。

In the geologic timescale, the Valanginian is an age or stage of the Early or Lower Cretaceous. It spans between 139.8 ± 3.0 Ma and 132.9 ± 2.0 Ma (million years ago). The Valanginian stage succeeds the Berriasian stage of the Lower Cretaceous and precedes the Hauterivian stage of the Lower Cretaceous.
