摘要
Abstract
In the recently discovered Mansurovo locality (Orenburg Region, Pervomaysky District, Lower Triassic, Lower Olenekian Substage, Gostevka Formation), in addition to macroflora and bone remains of tetrapods, numerous ichnofossils were found, including tracks of various invertebrates and archosauromorphs. In this paper, we describe swim tracks of the archosaurs Characichnos isp. from this locality, discovered for the first time in Eastern Europe.
