Functions to describe sampling and diversity dynamics of fossil occur-rence datasets (e.g. from the Paleobiology Database). The package includes methods to calcu-late range- and occurrence-based metrics of taxonomic richness, extinction and origina-tion rates, along with traditional sampling measures. A powerful subsampling tool is also in-cluded that implements frequently used sampling standardization methods in a multiple bin-framework. The plotting of time series and the occurrence data can be simplified by the func-tions incorporated in the package, as well other calculations, such as environmental affini-ties and extinction selectivity testing.
