Based on its completeness, the Bottaccione-Contessa composite section (BCCS; Gubbio area, Italy) has been analyzed to infer the paleobathymetry throughout the interval spanning the uppermost Albian to the lower Danian.

Abstract

Based on its completeness, the Bottaccione-Contessa composite section (BCCS; Gubbio area, Italy) has been analyzed to infer the paleobathymetry throughout the interval spanning the uppermost Albian to the lower Danian. Foraminifera are generally abundant and well preserved and the assemblages are dominated by planktonic foraminifera (planktonic/benthic ratio < 99%). The investigation of the benthic foraminiferal assemblages allows us to infer a lower bathyal depositional environment along most of the BCCS. A somewhat shallower deposition paleodepth is estimated for the Danian part of the BCCS, although this difference could be ascribed to the post- Cretaceous-Paleogene (K-Pg) boundary effect. This study further enhances the application potential of benthic foraminiferal assemblages as a paleobathymetric proxy.
