CS chart containing the Quaternary and Cambrian GSSPs and new stages (v 2018/07) is now released! http://www.stratigraphy.org/index.php/ics-news-and-meetings/120-ics-chart-containing-the-quaternary-gssps-and-new-stages-v-2018-07-is-now-released http://www.stratigraphy.org/ICSchart/ChronostratChart2018-07.pdf "proposal submitted by ICS that subdivides the Holocene Series into the Greenlandian (11,700 yr b2k), Northgrippian (8326 yr b2k), and Meghalayan (4200 yr before 1950) stages, and that these stages correspond to the Lower, Middle and Upper Holocene subseries. A speleothem collected from the Mawmluh Cave, northern India, serves as the GSSP for the Meghalayan Stage and will be curated in the Smithsonian Institution, Washington DC." Yours, Paul H.
