Short summary

A study in the equatorial Atlantic Ocean (Ocean Drilling Program Site 1260) reveals the deep-sea biotic response to a middle Eocene warming event 41.52 million years ago. Low-diversity benthic foraminiferal assemblages indicate environmental stress during the warming event. We argue that the biotic response in the deep sea and carbonate dissolution at this site were likely related to its paleoceanographic setting.
