   Sammanfattning : This investigation examines the distribution of conodont elements in the upper Lower Ordovician (Arenig) Volkhov Stage of the Mäekalda section situated in the Tallinn area, north-central Estonia. Slightly more than 36,000 conodont elements from 18 samples were investigated, and the biostratigraphic result was compared to previous works on conodont biostratigraphy from localities in south-central Sweden.
