Description
Summary: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.
