Bukobay Svita (Russia)

The Bukobay Svita (also anglicized as Bukobay or Bukobai Formation) is a Middle Triassic geological unit in Russia.^[1][2][3] It is composed primarily of red or grey lacustrine sediments, reconstructing a humid and marshy depositional environment. Bukobay is the youngest section of a Triassic terrestrial succession exposed south of the Ural Mountains. It is equivalent to a biostratigraphic unit, the Bukobay Gorizont, which is also called the "Bukobay Horizon" or "Mastodonsaurus" fauna).
