Tournaisian conodonts from the basinal carbonates of the Krzeszowice area, southern Poland

Abstract

The Lower Carboniferous succession, exposed in the Krzeszowice area of southern Poland, is predominantly composed of shallow-water carbonates. Only one lithological unit of spiculitic limestones was deposited in a basinal environment. The conodont fauna recovered from this unit is indicative of the Gnathodus cuneinformis Zone. Although the unit is lithologically monotonous, the conodonts show an irregular distribution through the section. This distribution was most probably controlled by the influence of the environmental factors and it does not reflect the evolution of the conodont fauna.
