Figure 13. Depth-age profile determined from geomagnetic reversals and diatom and calcareous
nannofossil datums. The curve fit to the paleomagnetic data is an interpolation that passes through
all data points within the data set and matches the slope at those points. Diatom and calcareous
nannofossil datum intervals are marked with solid (diatom) and open (nannofossil) triangles. B =
base/first occurrence, T = top/last occurrence.
