Abstract

Górno-wizeńska fauna konodontów z wapienia węglowego okolicy Krzeszowic koło Krakowa This paper concerns the conodonts found in the Upper Visean limestone in the Czernka Valley at Czerna N of Krzeszowice, 30 km W of Crącow. One of the assemblages found, consisting of 73 species, represents the limit between the Gnathodus mononodosus and Gnathodus girtyi collinsoni zones, another assemblage, much less diversified, consisting of 17 species, seems to indicate the lower part of the D3 zone, probably Gnathodus mononodosus zone.
