Abstract
A description is given of trace fossils from the Lower Triassic Gostevskaya Formation of the Mansurovo locality, Orenburg Region, represented by counterimpressions on the lower contact of sandstone with wave ripples. The ichnological characteristics of the trackways and their individual imprints are similar to the ichnospecies Diplichnites triassicus (Linck, 1943), which is widespread in fluvial and lake sediments of the Carboniferous-Triassic of Europe and North America. For D. triassicus most likely the trace maker from the group of branchiopod arthropods Notostraca, which moved in the aquatic environment. Most likely, the microbial mat developed on the surface of the sand substrate acted as a trace carrier, and the subsequent preservation and burial of arthropod trackways took place with the direct participation of the microbial mat.
