Trace fossils recording the activity of organisms are common in the Ordovician terrigenous deposits of Tuva. The richest location of ichnofossils was found in the Chirgaky section in the western part of the region. Ichnofossil taxa such as Dimorphichnus Seilacher and Helmintopsis Heer have already been sporadically recorded in other regions of the world. Along with them, the author found predominant trace fossils which should be attributed to a new species of a new subgenus of the genus Rusophycus Hall.
