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 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian stage and underlies the Coniacian stage.[1]

At the beginning of the Turonian ananoxic event took place which is called the Cenomanian-Turonian boundary event or the "Bonarelli Event".
