International Field Workshop on the Marwar Supergroup, Rajasthan, India

Towards an Ediacaran Time Scale: Problems, Protocols, and Prospects

“…The stated goal of the Subcommission on Ediacaran Stratigraphy is to facilitate international communication and scientific cooperation in Ediacaran stratigraphy, with the ultimate goal to define, by means of GSSPs, a hierarchy of chronostratigraphic units that provide the framework for global correlation. In the past decade, the Subcommission on Ediacaran Stratigraphy and its predecessor organized and sponsored several field workshops to examine potential criteria for Ediacaran subdivision and correlation (Moczydlowska-Vidal et al, 2008;Kumar and Sharma, 2010;Xiao et al, 2011;Gehling and Droser, 2012;Kumar and Sharma, 2012;Narbonne et al, 2012a;Kaufman et al, 2014;Pandey and Dimri, 2014;Singh and Ansari, 2014;Xiao and Sharma, 2014;Xiao et al, 2014b). As part of the efforts toward the establishment of intra-Ediacaran GSSPs, we have encouraged-at various scientific meetings and workshops, notably the 2014 Ediacaran Workshop in Wuhan, China, and the STRATI 2015 meeting in Graz, Austria-community-wide discussions about the subdivision and correlation of Ediacaran strata.…”
