#' Paleobiology Database occurrences of Pliocene fossil bivalves
#'
#' A dataset containing the (palaeo)coordinates and genus identifications of
#' 8,000 marine bivalves from the Pliocene (ca. 5.3-2.6 Ma). Records with
#' uncertain or unaccepted taxonomic names, non-marine palaeo-environments,
#' or missing coordinates are excluded from the original download
#' (24 June 2022).

#' @format A data frame with 8095 rows and 9 variables:
#' \describe{
#'   \item{genus}{Latin genus identification. Subgenera are not elevated.}
#'   \item{paleolng, paleolat}{Coordinates of an occurrence, rotated to
#'   its palaeogeographic location with the tectonic plate model of
