The Santonian is an age in the geologic timescale or a chronostratigraphic stage. It is a subdivision of the Late Cretaceous Epoch or Upper Cretaceous Series. It spans the time between 85.7 ± 0.2 mya (million years ago) and 83.6 ± 0.2 mya. The Santonian is preceded by the Coniacian and is followed by the Campanian.
