The Eocene‐Oligocene transition (EOT) marked the initiation of large‐scale Antarcticglaciation. This fundamental change in Cenozoic climate state is recorded in deep‐sea sediments by arapid benthic foraminiferalδ18O increase and appearance of ice‐rafted debris in the Southern Ocean.However, we know...
