Figure F8. A. Calcareous microfossil and radiolarian biozones at Site 1261. Shaded boxes indicate the absence of microfossils suitable for dating. Dashed line indicates uncertain location of biozone boundary of >10 m. In A, the calcareous nannofossil zonation, Subzones NP9a and NP9b refer to nannofossil assemblages in Zone NP9 above and below the P/E boundary, respectively.
