Middle Eocene diatoms from the South Atlantic.

Abstract

The biostratigraphic distribution of nearly 60 diatom species in a 67.1-m, continuously piston cored middle Eocene (Lutetian) section is documented. The first and last appearance datums of nine stratigraphically important species are illustrated. These datums may be of use in regional correlations of Lutetian sediments in the South Atlantic Ocean. -Author
