Notes: Age assignments of biostratigraphic zones are taken from Shipboard Scientific Party (1999). Depth indicated = the midpoint depth between two samples. Error = the distance from midpoint depth to the two samples that mark the top and bottom of that interval. LSR = linear sedimentation rate, FO = first occurrence, FCO = first common occurrence.
