| Summary: | This article outlines the results of the first-ever ichnological study of the Middle Devonian clastic succession in the South Tatar Arch. The analysis of the stratigraphic distribution of trace fossils in the boreholes revealed several levels with biogenic structures such as ichnofossils and bioturbation, which proved useful for the correlation of the boreholes. The boundary interval of the Pashyian and Timanian Horizons is made up by a succession of three layers: bioturbated siltstones with Spirophyton burrows, limestones, and mudstones with Lingulichnus burrows. The interval can be traced over the entire area of the South Tatar Arch and may serve as an additional marker for the boundary between the horizons. |
