A multiproxy study of the Katian and Hirnantian in the Puhmu core in NE Estonia resulted in new data on chitinozoan and brachiopod biostratigraphy.
Precise time-correlation in the Ordovician can be achieved by biostratigraphical methods, particularly using graptolite, conodont and chitinozoan distribution (biozones).
In the chitinozoan biozonation, the Eisenackitina rhenana Subzone of the Laufeldochitina stentor Zone corresponds to the lower part of the Kukruse Stage (Nolvak & Grahn 1993; Nolvak 1997).
