Conodonts, scolecodonts, and foraminifers were studied from Frasnian age deposits of Well 16 Schigry (Nizhnekrasnoe village, Voronezh anteclise). Six conodont complexes are identified: I in Timan regional stage, II and III in Sargaevo regional stage, and IV and VI in Semiluky regional stage. Correlation by local zonal units and Standard Conodont Zonation is performed. Shallow environment is confirmed for Timan regional stage, the deepest environment settings is confirmed for Semiluky regional stage. Five scolecodont complexes are identified: complexes 1 and 2 for Sargaevo regional stage, complexes 3 and 4 for Semiluky regional stage, and complex 5 for the upper part of Semiluky regional stage and Voronezh regional stage. Foraminifers are presented by two complexes: first for Sargaevo regional stage and the second for the Semiluky regional stage. The characteristic microfossils species are given in plates.
