occSilur

A dataset containing the (palaeo)coordinates and genus identifications of
13,500 marine brachiopods from the Silurian (443.1-419 Ma). Records with
uncertain or unaccepted taxonomic names, non-marine palaeo-environments,
or missing coordinates are excluded from the original download (29 July 2022).
Taxonomic synonymisation and removal of stratigraphic outliers
follows the <code>fossilbrush</code> vignette example of cross-correlation with the
Sepkoski range-through database <code>[fossilbrush::sepkoski()]</code>.

datasets

Divide taxonomic occurrence data into geographic regions of fair
comparison, with three customisable methods to standardise area and extent.
Calculate common biodiversity and range-size metrics on subsampled data.
Background theory and practical considerations for the methods are described
in Antell and others (2023) <doi:10.31223/X5997Z>.
