Abstract:
The interval spanning the uppermost Eocene to the lower Oligocene was a time of major climatic and oceanographic change, including major changes in sediment composition and faunal assemblages. Here we examine the radiolarian fauna during the Eocene-Oligocene transition (40-30 Ma) from three sites: Ocean Drilling Program Site 1218 and Integrated Ocean Drilling Program Sites U1333 and U1334, all of which appear to contain complete sections of the Eocene/Oligocene boundary and to have been located near the Pacific Equator during this time interval. Using previous work that interrelated the stratigraphic position of samples from all three sites, the abundance and first and last appearances of 76 stratigraphically important radiolarian species, species groups, and variant forms are documented in >600 samples. This quantitative analysis of species abundance has allowed us to accurately define 109 first and last appearance datums and to document the reworking of older microfossils into younger sections.
