Abstract

The upper Silurian-Lower Devonian Monte Cocco II section, located in the eastern part of the Carnic Alps, yielded abundant conodonts from five conodont biozones (snajdri, crispa, eosteinhornensis s.l., detortus and woschmidti). The eosteinhornensis s.l. interval Zone is introduced here to replace the “ Oz. remscheidensis i.Z.” of Corradini & Serpagli (1999). The Silurian/Devonian boundary is located in the upper part of the section; problems related to the accurate location of the Silurian/Devonian boundary on the basis of conodonts are discussed. A new taxon of the genus Pelekysgnathus is described, but left in open nomenclature. A few taxonomic notes on other selected taxa are also presented.
