Summary: Benthic foraminifers were studied from lower Paleocene through Upper Oligocene sections from Sites 747 and 748. The composition of the benthic foraminifer species suggests a middle to lower bathyal (600-2000 m) paleodepth during the Neogene and a probable upper abyssal (2000-3000 m) paleodepth during the Paleocene at Site 747. Site 748 is thought to have remained at middle to lower bathyal paleodepths throughout the Cenozoic. Principal component analysis distinguished 4 major benthic foraminifer assemblages: a Paleocene Stensioina beccariiformis assemblage at Sites 747 and 748, an Early Eocene Nuttallides truempyi assemblage at lower bathyal Site 747, an Early through Middle Eocene Stilostomella-Lenticulina assemblage at middle bathyal Site 748, and a latest Eocene through Oligocene Cibicidoides-Astrononion pusillum assemblage at both sites. Major benthic foraminifer changes, as indicated by the principal components and first and last appearances, occurred at or close to the Paleocene/Eocene boundary, and in the Late Eocene close to the Middle/Late Eocene boundary.
