Paleogene benthic foraminifers from the southern Indian Ocean (Kerguelen Plateau): biostratigraphy and paleoecology

Abstract

The composition of the benthic foraminifer species suggests a middle to lower bathyal paleodepth during the Neogene and a probable upper abyssal paleodepth during the Paleocene at Site 747. Site 748 is thought to have remained at middle to lower bathyal paleodepths throughout the Cenozoic. Principal component analysis distinguished four major benthic foraminifer assemblages. Major benthic foraminifer changes occurred at or close to the Paleocene/Eocene boundary, and in the late Eocene close to the middle-late Eocene boundary. -from Authors
