Late Cretaceous (Campanian) carbon isotope events, sea-level change and correlation of the Tethyan and Boreal realms

Carbon stable-isotope stratigraphy provides unique insights into environmental change during the Campanian, the longest (83.5–71.3 Ma), but least well-understood stage of the Late Cretaceous. A new carbon isotope (δ13C) profile for a 500-m-thick Campanian–basal Maastrichtian Tethyan pelagic–hemipelagic section near El Kef, northern Tunisia, is calibrated using data from a biostratigraphically well-constrained succession at Kalaat Senan. The...
