We studied a high - resolution multiproxy data set, including
magnetic susceptibility (MS), CaCO3 content, and stable isotopes (δ18O and δ13C), from the stratigraphic interval covering the uppermost Maastrichtian and the
lower Danian, represented by the pelagic limestones of the Scaglia Rossa Formation continuously exposed in the classic sections of the Bottaccione Gorge and the Contessa Highway near Gubbio, Italy.
