At the 78th Annual Meeting of the North American Commission on Stratigraphic Nomenclature, 16 October, 2023, a hybrid meeting hosted in Pittsburgh, Pennsylvania, the Commission voted unanimously to accept the revision of Articles 7 and 20 of the North American Stratigraphic Code (North American Commission on Stratigraphic Nomenclature, 2021) as printed below. These replace all older versions of the specified Articles. An application for this revision (MacNaughton et al. 2022) was published in Stratigraphy more than one year prior to the Annual Meeting; thus, the vote on this application for revision follows Article 21 of the Code.
