The conodont stratigraphy of the lower Lochkovian part of the famous Cellon section is presented. The association includes twenty-two taxa belonging to nine genera, and allows discriminating the two biozones of the lower Lochkovian (Icr. hesperius and Icr. postwoschmidti zones). Three taxa (Zieglerodina formosa, Z. mashkovae and Z. prosoplatys) are reported for the first time from the Carnic Alps, and other two species of Zieglerodina, probably new, are described in open nomenclature.
