Add article description

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).

Fossil content

Notable components of the Bukobay fauna include "Mastodonsaurus" torvus (a giant capitosaur amphibian), Malutinisuchus gratus and Energosuchus garjainovi, the insect Mesoneta uralensis, Elephantosaurus jachimovitschi (a large dicynodont), and Chalishevia cothurnata (the youngest known erythrosuchid). Temnospondyls include Bukobaja enigmatica, Cyclotosaurus, Plagioscutum caspiense and Plagiorophus paraboliceps, with Ceratodus orenburgensis and C. bucobaensis as fish. The flora is also diverse, including Equisetites arenaceus (a species of giant horsetails) and Ladinian-age palynomorphs.[4][5]
