Interval table for linking and standardising intervals

Description

This dataset provides the interval table used for updating the intervals in Sepkoski's fossil marine animal genera compendium with the International Geological Time Scale 2022. This table was generated based on published literature and the GeoWhen Database. In the majority of cases, this was a clear conversion. However, in several cases reasonable interpretation was required.
