collSilur

A dataset containing the (palaeo)coordinates and recorded marine environment
of 8,000 PBDB fossil collections from the Silurian, formatted and downloaded
from the Paleobiology Database on 24 June 2022.

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>.
