Paleontological Journal Aims and scope Submit manuscript

Abstract

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.
