Abstract
This paper describes the conodont species found for the first time in Abrek Bay in the upper part of the Lower Triassic deposits, which are provisionally assigned through ammonoids to the Anasibirites nevolini zone. The study of the conodonts from these layers has made it possible to identify the assemblage composed of the species Concervatella concervativa (Muller), Ellisonia triassica Muller, Foliella gardenae (Staesche), Neospathodus novaehollandiae McTavish, N. posterolongatus Zhao et Orchard, N. spitiensis Goel, and Novispathodus waageni (Sweet) occurring in both the Anasibirites nevolini zone and the Mesohedenstroemia bosphorensis underlying zone, belonging to the Olenekian bottom, and also the species Triassospathodus aff. homeri (Bender) and T. cf. symmetricus (Orchard) that are more characteristic for the overlying ammonite zones of the Olenekian top.
