The current basal Emsian GSSP was defined in the Zinzil'ban Gorge in the Kitab State Geological Reserve, Uzbekistan based on FAD of conodont Polygnathus kitabicus YOLKIN, WEDDIGE, IZOKH & ERINA. Further research revealed, that this GSSP is considerably older than the base of the classical Emsian in German sense and fall in lower half of the original Pragian. In 2019, the Subcommission on Devonian Stratigraphy decided to look for a new appropriate section for the redefined basal Emsian GSSP, the most promising candidates are situated in the Spanish Central Pyrenees and in the Prague Synform. The main task of the ongoing project is to complete robust data (biostratigraphy, sedimentology, faunal content, geochemistry and petro-physical data) for the proposal for a GSSP candidate section in the Prague Synform. The main attention is focused on several sections with the Bohemian Graptolite Event or with its presumed equivalent.
