Data standards that pertain to the temporal, age, and related geological context of
fossil specimens contained in the databases described here.
↵* BISON has a dwc:basisOfRecord field that can be used to search on fossil records,
but the corresponding geological context data are not included, e.g., in a .csv file
of the extinct taxon Equus scotti retrieved on 25 August 2016. GBIF
aggregates data that are both DwC and non-DwC compliant.
↵† Although group, formation, and member are similar to the DwC data standards
terminology, those for PBDB are not DwC compliant.
↵‡ These descriptors pertain to the geological, temporal context, and age of the
fossil sites included in this database. Because lithology is included in the PBDB,
the corresponding lithology standards are included here. Some data standards, e.g.,
notes, are not included here; thus some of the data standards sets are abridged.
Extensive additional documentation is provided in http://www.neotomadb.org/uploads/NeotomaManual.pdf.

Records include many different kinds of data related to, e.g., vertebrate faunal
remains, paleobotany, invertebrates, geochemistry, stratigraphy and geochronology.
They do not refer to vouchered museum specimens like some of the other
