Abstract: 

The Makarovian Regional Substage (Famennian Stage) stratigraphic interval is defined more accurately in the Kuk-Karauk stratotype section (Sikasya River, west slope of the Southern Urals) by conodonts. It is equal to the Pa. minuta minuta, Pa. crepida, Pa. rhomboidea, Pa. marginifera marginifera conodont zones. The absence of intervals equal to the Pa. termini, Pa. glabra prima, Pa. glabra pectinata and Pa. gracilis gracilis zones is testifies to a hiatus. The Pa. crepida and Pa. rhomboidea zones are revealed in the studied section for the first time. Conodont complexes are characterized by rich taxonomic and quantitative diversity (six genera and 48 species). Species of the genus Palmatolepis (up to 92%), which are representatives of deepwater palmatolepid biofacies, predominate.
