Fig. 5: Site U1516 benthic foraminifera assemblage shift over Oceanic Anoxic Event 2 (OAE2).

Range chart, abundance, Fisher α diversity, Correspondence Analysis (CA) Axis 1, and carbon isotopes from benthic foraminifera. A significant shift in assemblage is seen either side of the low carbonate horizon. Axis 1 of the CA correlates with the proportion of infaunal / high productivity species (Supplementary data 2). Thus, high values above the low carbonate horizon suggest high organic carbon flux in the later stages of OAE2.
