Fig. 7: Temporal correlation of planktic foraminifera, dinoflagellate cysts, and carbonate geochemistry of the Sidi Ziane section.

From: Ocean freshening near the end of the Mesozoic

A Bulk sediment carbon isotope (δ13C, ‰); B oxygen stable isotope (δ18O, ‰); C calcium carbonate content (CaCO3 %); D Relative abundance (%) of selected planktic foraminifera genera; E Relative abundance (%) of selected dinocysts. Biozone ranges are marked by: 1 = Gansserina gansseri; 2 = Plummerita hantkeninoides; 3 = Archaeoglobigerina cretacea. The age for the C29r/C30n reversal is based on the Geological Time Scale 202070.
