Comment:
Age determined from composite depth and the orbitally tuned age models of Schmidt et al., (2006, doi:10.1029/2005GC000957) and Haug and Tiedemann (1998, doi:10.1038/31447) and biostratigraphic models (Chaisson and d'Hondt, 2000, doi:10.2973/odp.proc.sr.165.010.2000; Kameo and Bralower, 2000, doi:10.2973/odp.proc.sr.165.012.2000). Measured on Globigerinoides sacculifer 300-355 µm
