  skos:definition "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 86.3 ± 0.7 mya (million years ago) and 83.6 ± 0.7 mya. The Santonian is preceded by the Coniacian and is followed by the Campanian. The Santonian Stage is named after the city of Saintes (France) in the region of Saintonge, where the original type locality is located. The base of the Santonian Stage is defined by the appearance of the inoceramid bivalve Cladoceramus undulatoplicatus. The GSSP (official reference profile) for the base of the Santonian Stage is located near Olazagutia, Spain. The Santonian's top (the base of the Campanian Stage) is informally marked by the extinction of the crinoid Marsupites testudinarius.

On le date entre −86,3 ± 0,5 et −83,6 ± 0,2 Ma, après le Coniacien et avant le Campanien. Le Santonien doit son nom à la ville française de Saintes (Mediolanum Santonum), en Charente-Maritime. Sa base est définie par l'apparition du bivalve Cladoceramus undulatoplicatus (Roemer) et son sommet par la disparition du crinoïde Marsupites testudinarius.
