Abstract: Permo-Carboniferous sedimentary rocks, which belong to the pre-Jurassic basement of the Eastern Pontides, occur in the Cebre relative autochthon and the Hamurkesen thrust sheet in the Demirözü area, Bayburt, NE Turkey, and consist of the Çatalçeşme and Hardişi formations, respectively. Some limestone beds of the Çatalçeşme Formation in the village of Çatalçeşme produced the first conodont faunas encountered in Palaeozoic sediments of the Eastern Pontides. A rich conodont fauna with abundant Neognathodus bassleri (HARRIS & HOLLINGSWORTH), less Idiognathodus sp. and Streptognathodus elegantulus STAUFFER & PLUMMER, and rare Gondolella sp. were obtained from a densely-packed bioclastic packstone bed on the west side of the Deliklitaş Hill, about 2 km south of the village of .ataleßme (Demirözü, Bayburt). This fauna indicates a late Middle Pennsylvanian age (Desmoinesian on the North American scale; late Moscovian on the Russian scale). Furthermore, Pa elements of Streptognathodus elongatus GUNNELL, a long-ranging form, were obtained from two samples of the Çatalçeşme-Cebre road cut section, about 1250 m west of the village of Çatalçeşme.

The conodonts of the Çatalçeşme Formation are geographically widespread forms, and do not show any provinciality.
