Fourteen conodont species are described from composite Permian (Asselian-?Ufimian) sections of Bjørnøya. Sample richness is generally good with 30-100 specimens per kilo of dissolved carbonate rock in productive samples. The investigated faunas make it possible to propose an Asselian age for the Kapp Duoer Formation, a latest Artinskian age for the upper part of the Hambergfjellet Formation, and a Kungurian-Ufimian age for the Miseryfjellet Formation. These ages are generally in agreement with published datings based on fusulinaceans, brachiopods and bryozoans. Regionally, the con odont faunas are similar to those of other Arctic regions. The generic composition makes it possible to distinguish three conodont biofacies: a shallowest lagoonal Streptognathodus biofacies; a slightly more offshore but still high energy biofacies with Neostreptognathodus and Sweetognathus, but without Neogondolella; and a youngest more offshore and probably cooler biofacies with the exclusive presence of Neogondolella and Xaniognathus. Conodont elements are generally well preserved although discrete denticles are cornrnonly broken off. The elements show little thermal alteration with CAI values between 1.5 and 2.0 indicating a burial temperature of 50-140°C.
