Notes: T = top of taxon stratigraphic range, B = bottom of taxon stratigraphic range. Midpoint = is the middle depth between the sample where the taxon occurs and the adjacent sample where it does not occur. Stratigraphic error = one-half the distance between these two samples. Datum level code = the number assigned to the datum level on Figure F10. Fossil groups: 1 = calcareous nannofossils, 4 = planktonic foraminifers.
