Miospore assemblage from the Lode Member (Gauja Formation) in Estonia and the Middle-Upper Devonian boundary problem

A miospore assemblage, equivalent to that of the Ancyrospora incisa-Geminospora micromanifesta (IM) Subzone of the East European Platform, was identified in a sample from the old refractory clay quarry at Kullatova, SE Estonia. It permits us to correlate the Gauja Formation of the Baltic area with probable coeval stratigraphic units in the adjacent regions - Belarus and the Moscow Basin. The Middle-Upper Devonian boundary probably lies close to, but somewhat above, the top of the Gauja Formation.
