FIGURE 2 in RNames, a stratigraphical database designed for the statistical analysis of fossil occurrences - the Ordovician diversification as a case study
FIGURE 2. Structure of algorithm for time binning of stratigraphical units of the RNames Database (available under https://github.com/bjoekroe/RNames). Time bins are selected via three correlation routes (colour codes) and six rules resulting in six tables with referenced bins from which only those are selected which are most precise (i.e., range through lowest number of bins). Abbreviations: bio.unit, biostratigraphic unit; non-bio. unit, non-biostratigraphic unit. Colour code: red, correlation exclusively based on biostratigraphy; orange; correlation indirectly based on biostratigraphy; yellow, correlation based on direct or indirect assignments to time bins. -> arrow refers to referenced relations in RNames.
