Abstract
A combination of high resolution sampling and reevaluation of the ''ex tinction'' of the Pleistocene radiolarian, Stylatractus universus Hays , has resulted in precise placement of the .425 Ma datum at 24.8-24.4 mbsf in the siliceous sediment section recovered by ODP from Kerguelen Plateau Site 745. This reevaluation reconciles earlier differences be tween diatom and radiolarian stratigraphies of the Brunhes section of the sediments.
