This paper presents new data on the age of the Mastodonsaurus tetrapod fauna (Middle Triassic) of the East European Platform. The analysis of the section and ichnofossils showed that the sedimentation in the Eltonian time occurred mostly in continental conditions with episodic transgressions, whereas the Inderian time was characterized by gradual tectonic subsidence of the territory from the tidal beach zone to the sublittoral zone of a brackish water basin.
