Comment:
Age above 366 mbsf from Roberts et al. (2003). Age below 366 mbsf applies magnetic stratigraphy of Wilson et al. 1998. Our age model (Fig. S1) remains within the shaded area of their figure 7, but places the E-O boundary at 547m, applying new biostratigraphic observations indicated in Supplementary Data Table 1.
