Figure F21. Nannofossil diversity and abundance plots for the PETM in Hole 1209B. Nannofossil abundance records are percent abundances relative to the total non-Toweius-Coccolithus fraction except for Toweius spp. The number of nannofossil fragments relative to 100 whole nannofossils is used as a preservation index. FCO = first common occurrence, LCO = last common occurrence (after Gibbs et al., 2006).
