Hesperomys Project v23.6.0

An export of data from the Hesperomys Project version 23.6.0. The Hesperomys Project is a database of taxonomy and nomenclature, focused on mammals but also covering some other groups, principally other fossil tetrapods. The database contains information such as:

• Taxonomic classification for all mammals, living and extinct
• References to original citations for the vast majority of names
• Type specimens and type localities for numerous names

The full database is available online at hesperomys.com. This export contains:

• name.csv: Data on names, including taxonomic context, authority, citation, type locality, type specimen, and classification of the etymology.
• taxon.csv: Data on taxa, including classification and authority
• collection.csv: Data on collections that contain type specimens, including name, location, and number of type specimens in the database

The code used to generate the exports is on GitHub.

Release notes for version 23.6.0:

• Database
  • Add numerous new names and recently published articles. Since the previous release,
    1226 additional names and 1450 additional articles have been added.
  • Add given names or initials for a number of name authors that were given only as
    family names.
  • Remove about 200 duplicate articles
  • Remove some duplicate names, mostly in the turtles
  • Remove uses of the legacy "dubious" status
  • Fix some incorrect parent taxa
  • Add numerous new fossil taxa based on the recent literature
  • Further taxonomic changes for extant mammals for alignment with the MDD
  • Simplify the treatment of justified emendations, using two names instead of three
  • Change many _page_described_fields to follow a more consistent format
• Backend
  • Further checks for publication dates. Distinguish between "parts" (separately
    published portions of a larger work) and "chapters" (simultaneously published
    portions of a larger work, usually with different authorship). Enforce that chapters
    have the same publication date as their enclosing work. Allow ranges of years (e.g.,
    "1848-1852") only for works composed of parts, not for names or for other kinds of
    works.
  • More sophisticated processing and validation of LSIDs in order to display correct
    publication dates.
  • Enforce that the page_described and original_rank fields are set for all names
    with original citations.
  • Add new nomenclature statuses to distinguish between unpublished names, separating
    out "unpublished_thesis" (unpublished because named in a thesis),
    "unpublished_electronic" (named in an electronic work that does not fulfill the
    ICZN's criteria for publication), "unpublished_supplement" (named in electronic
    supplementary material only), and "unpublished_pending" (not yet available, but
    expected to be made available by print publication).
• Frontend
  • Better ordering for various lists of names and articles (e.g., ordering by page)
