Neogene Planktonic Foraminifers from DSDP Leg 40 Sites 360 and 362 in the Southeastern Atlantic

Abstract

From the documentation of the Neogene planktonic foraminifer species from 126 samples of DSDP Leg 40 Sites 360 and 362 in the southeastern Atlantic, a comparison is made of the two sets of faunas within the framework of the established Austral bio-stratigraphic zonal scheme. A species diversity difference exists between the two sites with a greater species number at Site 362 due to the migration southwards of exotic species which did not reach Site 360. A strong affinity exists between the faunas of Sites 360 and 362 and those of southeastern Australia and New Zealand, probably due to their similar latitudinal positions and to the circum-Antarctic current connection.
