Short summary
In this study, we propose an age framework for an interval of 4.8–3.1 million years ago, using fossil records of marine plankton such as diatoms and radiolarians derived from a sediment core collected in the Southern Ocean. Specifically, a total of 19 bioevents (i.e., extinction/appearance events of selected age marker species) were detected, and their precise ages were calculated. The updated biostratigraphy will contribute to future paleoceanographic work in the Southern Ocean.
