Snyder, Scott W.; Mueller, Carla; Miller, Kenneth G. (1984): Eocene-Oligocene boundary; biostratigraphic recognition and gradual paleoceanographic change at DSDP Site 549. Geological Society of America (GSA), Boulder, CO, United States, Geology (Boulder), 12 (2), 112-115, georefid:1984-029695

Abstract:
Goban Spur in the northern Bay of Biscay, upper Eocene-lower Oligocene nannofossil chalks. The Eocene-Oligocene boundary as identified by nannofossils does not coincide with that recognized using planktonic foraminifers. No dramatic nannofloral or planktonic foraminiferal change occurred at the boundary. There was a gradual transition from warm-water to cool-water assemblages through the late Eocene, with more intense cooling indicated by low-diversity assemblages in lower Oligocene sediments. A major benthic foraminiferal faunal change occurred in the early late Eocene. No major benthic assemblage changes occurred at the Eocene-Oligocene boundary.--Modified journal abstract.
