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.

俄罗斯最年轻的三叠纪土地脊椎动物组合：组成和约会

摘要

俄罗斯最年轻的三叠纪动物脊椎动物组合来自Lysov地区（奥伦堡地区）南西拉拉尔的Bukobay组（中三叠纪）上层。除了四足动物和鱼类以外，在该地区还发现了双壳类软体动物，多样的大型植物和丰富的孢粉组合。通过对孢粉组合的研究，可以可靠地确定骨岩石的拉丁时代。Bukobay时间代表着南西拉乌拉尔动物群和植物区系演化的一个独立的（拉丁）阶段。
