The GSSP is exactly 15m above this lithologic ...The authors are on the forefront of chronostratigraphic research and initiatives surrounding the creation of an international geologic time scale.

A stratigraphic boundary, surface, or interface across which there is a significant change in biostratigraphic character. A biohorizon has no thickness and should not be used to describe very thin stratigraphic units that are especially distinctive. 5. Subbiozone (Subzone) A subdivision of a biozone.

The age of a stratigraphic unit or the time of a geologic event may be expressed in years before present (before A.D. 1950). The "North American Stratigraphic Code" (North American Commission on Stratigraphic Nomenclature, 2005) recommends abbreviations for ages in SI (International System of Units) prefixes coupled with "a" for "annum": ka for kilo-annum (103 years); Ma for mega-annum (106 ...INTERNATIONAL CHRONOSTRATIGRAPHIC CHART International Commission on Stratigraphy Colouring follows the Commission for the Geological Map of the World (www.ccgm.org) Chart drafted by K.M.Cohen,D.A.T.Harper,P.L.Gibbard,J.-X.Fan (c) International Commission on Stratigraphy, March 20209th International conference on fossil insects, arthropods and amber with an associated fieldtrip on the Mesozoic of the Erdos Basin, China. 18 to 25 April 2023.

Sequence stratigraphy developed largely without formal guidance from any international stratigraphic commission over the past decades.
