Abstract

The assessment of the newly sampled conodont fauna and a review of previous studies on the Lochkovian/Pragian GSSP at Velká Chuchle (Barrandian) revealed evident discrepancies. The GSSP-defining taxon – Eognathodus sulcatus "eosulcatus" – occurs lower in the section than was formerly believed. It is pointed out that the GSSP has been defined on the basis of a specimen that has been never figured or described.
