Revision of biostratigraphic units honors priority for the sake of stability and precision in communication. However, the first biostratigraphic zonation to be described is not necessarily the most useful. Revision or new biozonations should be clearly defined and/or characterized, be more widely applicable, offer greater precision, and be more easily identified. Changes in nomenclature of biostratigraphic conform with changes in the names of taxa as required by the International Codes of Zoological and Botanical Nomenclature. Named biostratigraphic units will automatically change scope to accord with changes in the scope of taxa defining or characterizing them. A fossil name once used for a biozone is not available for use in a different zonal sense by a later author. If it is desirable to continue the use of a taxonomic term that is no longer valid, the term should be placed in quotation marks, e.g. "Rotalia" beccari Zone.
