“…Conodont‐based Silurian biostratigraphy is well established, and a high‐resolution biozonation has been worked out (Corradini & Corriga, ; Corradini, Corriga, Männik, & Schönlaub, ; Cramer et al, ; Jeppsson, Eriksson, & Calner, ; Männik, ; Schönlaub, Corradini, Corriga, & Ferretti, ; and references in these papers). Due to the sporadic and rare occurrences of biostratigraphically determinative taxa, identification of conodont biozonal units in the Laojianshan section is complicated, and only a few intervals can be dated reliably (Figure ).…”
