摘要：

This research is the first study of the Lower and Middle Permian deposits of the Omolon Massif and its eastern margins for traces of vital activity of benthos. As a result, seven genera of trace fossils have been identified: Thalassinoides, Phycodes, Teichichnus, Chondrites, Zoophycos, Ophiomorpha (?), Rhizocorallium, referred to two ichnofacies: Zoophycos and Crusiana. Our conclusions do not contradict the previously formed assumption that the central part of the Omolon Basin was shallow and gradually deepened closer to the coast during the Permian.
