Paleobiology Database occurrences of Silurian fossil brachiopods
Description
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 fossilbrush vignette example of cross-correlation with the
Sepkoski range-through database [fossilbrush::sepkoski()].
