Stratigraphy
| Geological group: | Konvunchana | Formation: | Bugarikta | Member: | Dvuroginskii |
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Permo-Triassic boundary is usually placed at the base of the Bugarikta Formation because of its ostracods and conchostracans. The Bugarikta Formation is thought to be Early Triassic based on presence of charophyte algae and Eoperleidus of the Triassic fish family, Perleididae, or Late Permian based on its spore-pollen assemblage. | |||||
