Conodont dating of some Telychian (Silurian) sections in Estonia [PDF]
Estonian Journal of Earth Sciences, 2008 Several Telychian–Sheinwoodian strata exposed in Estonia are precisely dated using conodont biostratigraphy. The beds in the Valgu-1 section correspond to the uppermost Distomodus staurognathoides and Pterospathodus eopennatus ssp. n. 1 zones.
