Zusammenfassung:The youngest Triassic faunistic assemblage of land vertebrates in Russia originates from the upper beds of the Bukobay Formation (Middle Triassic) of the South Cis-Urals in the Lysov locality (Orenburg Region). Bivalve mollusks, a diverse macro-flora, and a rich palynological assemblage were identified at this locality, in addition to tetrapods and fish. The study of the palynological assemblage enabled reliable confirmation of the Ladinian age of the bone-bearing rocks. The Bukobay time represents a separate (Ladinian) stage in the evolution of the fauna and flora of the South Cis-Urals.
