Short summary
The Eocene–Oligocene transition was a pivotal interval in Earth's geological history, marked by cooling and Antarctic glaciation. Our research explores how Southern Ocean diatoms responded to these changes. By analyzing records from multiple sites, we revealed previously unrecognized diatom diversity, and identified distinct patterns in diversity and extinction. These findings deepen our understanding of the interplay between climatic perturbations and the biosphere.
