Abstract:

We investigated benthic foraminiferal assemblages from Sites 1218 and 1219, Ocean Drilling Program Leg 199, to understand the abyssal response of the eastern equatorial Pacific to the Oligocene climate. Globocassidulina subglobosa, Oridorsalis umbonatus, Gyroidinoides spp., Cibicidoides spp., and Pullenia spp. are common in the lower Oligocene, whereas Nuttallides umbonifer, a dominant species in carbonate corrosive deep water, often dominates the upper Oligocene assemblage at both sites.
