International commission on stratigraphy
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 ...The 'golden spike' marking the Ediacaran GSSP.

May 18, 2022 · The Anthropocene Working Group (AWG) is an interdisciplinary research group dedicated to the investigation of the Anthropocene. It was established in 2009 by the Subcommission on Quaternary Stratigraphy (SQS), a component body of the International Commission on Stratigraphy (ICS), and since then has worked to assess the Anthropocene as a geological time unit. Last month, the International Commission on Stratigraphy (ICS), the bureaucracy that governs geological time, declared we are living in a new geological age. No, it's not the Anthropocene, the much-debated proposal for a geological division defined by human impact on Earth.This group has been very active, inspiring many workers even from outside the traditional geosciences to participate in the concept and its definition.
