Notes: Datum levels listed here were used to generate Figure F12. FO = first occurrence of taxon, FCO = first common occurrence of taxon, LO = last occurrence of taxon, LCO = last common occurrence of taxon. Midpoint = 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 the sample where the taxon occurs and the adjacent sample where it does not occur.
