Table 2. Stratigraphic-range information for species in the Abelmann data set. Data given separately for species whose ranges are complete, and for the full data set, including taxa with range truncations. Dashes in the former columns indicate truncated values. These are replaced with the ages of the base and top of the section studied by Abelmann in the latter columns. Some taxa could not be used due to scattered primary occurrence data, or because the taxon was a genus level grouping of several species - (see comments column in table).
