A table of geological intervals and the earliest and latest corresponding international geological stages from the International Commission on Stratigraphy (ICS). The table was compiled using regional stratigraphies, the GeoWhen Database, temporal information from the Paleobiology Database and the Geological Timescale 2022. Some assignments were made with incomplete information on the stratigraphic provenance of intervals. The assignments in this table should be verified before research use. They are provided here as an example of functionality only.

## Usage

## Format

A data frame with 1323 rows and 3 variables:

interval_name

early_stage

Earliest (oldest) geological stage which overlaps with the interval

late_stage

## Source

Compiled by Kilian Eichenseer and Lewis Jones for assigning geological stages to ccurrences from the Paleobiology Database and the PaleoReefs Database.
