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()].
Format
A data frame with 13502 rows and 11 variables:
- order, family, genus
Latin order, family, and genus name, as synonymised against Sepkoski database
- paleolng, paleolat
Coordinates of an occurrence, rotated to its palaeogeographic location with the tectonic plate model of GPlates
- collection_no, reference_no
Unique identifiers for the collection and published reference containing the occurrence
- environment
One of 23 marine environment categories
- max_ma, min_ma
Bounds of the age estimate for an occurrence, according to the ICS 2013 geologic time scale.
- accepted_name
Original identification, including subgenus and species epithet if applicable, according to the latest PBDB accepted taxonomy at time of download
