Abstract

The distribution of benthic foraminifera across the Paleocene/Eocene (P/E) Boundary of the Contessa Road section allows us to compare the response of both calcareous hyaline and Deep Water Agglutinated Foraminiferal (DWAF) assemblages to the terminal Paleocene Benthic Extinction Event (BEE). The two groups are contemporaneously affected by the terminal Paleocene events. Quantitative analysis reveals a sharp change in DWAF assemblages indicating that a major perturbation on the sea floor occurred in coincidence with the P/E Boundary Carbon Isotope Excursion. The record of DWAF, however, indicates a gradual initiation of environmental changes beginning some 750 ky before the CIE with the entrance of shallower water taxa probably in response to the emplacement of saline intermediate water mass mixing surface waters to intermediate depths within the Tethys. This phase intensified in the last 250 ky of the Paleocene and terminated at the P/E boundary when the exit of shallower water taxa is recorded.
