Figure 10. DSDP Site 527 planktic foraminiferal stable isotope records plotted against depth for the three size fractions of Acarinina soldadoensis (90–150, 150–250, and 300–355 the position of the claystone interval within Core 24. The CaCO3 record reveals a low carbonate layer coincident with the PETM (Thomas et al., 1999).
