Turonian
Sign in to saveAlso known as Turonian Stage, Turonian Age
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.2 Ma and 89.8 ± 0.3 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage.

The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.2 Ma and 89.8 ± 0.3 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage.
At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Sea level fall took place in the latter part of the Turonian from the highstand at the beginning of the Turonian.
