The standing diversity of fossil primate species throughout the Cenozoic was estimated with a database for crown primates that combined temporal ranges for species from
the Paleobiology Database (http://paleodb.org; data downloaded on 16 October 2011) with additional taxon ranges from Hartwig [149] for species that were missing from
the Paleobiology Database.
To fill these gaps in the data, the Birmingham researchers compiled a new dataset from
the Paleobiology Database and used advanced statistical methods to estimate diversity and biogeographic changes.
