  skos:definition "Le Turonien est le deuxième étage stratigraphique du Crétacé supérieur. On le situe entre -93,9 et -89,8 ± 0,3 Ma, après le Cénomanien et avant le Coniacien. Le Turonien est défini d'après sa localité type de Tours (France) (latin Turones) ou sa région type de la Touraine (Turonia) situées sur ces terrains. Il s'appelle aussi l'Angoumien pour sa partie supérieure, du nom de la ville française d'Angoulême, et Ligérien pour sa partie inférieure, du nom latin de la Loire. Sa base biostratigraphique est définie par l'apparition de l'ammonite Watinoceras devonense. Son sommet correspond à l'apparition du bivalve Cremnoceramus rotundatus Tröger (= Cremnoceramus deformis erectus (Meek)). (Adapté de : <a href=\"https://fr.wikipedia.org/wiki/Turonien\">https://fr.wikipedia.org/wiki/Turonien</a>)"@fr, "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. 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. The Turonian (French: Turonien) was defined after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species Watinoceras devonense first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located in the Rock Canyon anticline near Pueblo, Colorado (United States). The top of the Turonian Stage (the base of the Coniacian) is defined as the place in the stratigraphic column where the inoceramid bivalve species Cremnoceramus rotundatus first appears.
