Upper Cambrian to Lower Ordovician conodonts of Łeba Elevation, NW Poland, and their stratigraphic significance

Abstract

Stratigraphy of Upper Cambr.ian to Lower Ordovician deposits of Łeba Elevation, NW Poland, is improved basing upon the ranges of condont species. Lower Tremadocian claystones overlying concordantly Upper Cambrian claystones are recognized in the section Białogóra 1. Glauconitites beginning the Ordovician carbonate sedimentary cycle are assigned mostly to the Arenigian Prionidodus elegans (Didymograptus balticus) Zone. Most Upper Cambrian to Lower Ordovician conodont species recorded in Łeba Elevation are described in the systematic part of the paper.
