Where: Evenk Autonomous District, Russian Federation (64.0° N, 100.0° E: paleocoordinates 57.2° N, 45.9° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Dvuroginskii Member (Bugarikta Formation), Lopingian to Lopingian (259.9 - 247.2 Ma)

• 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.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
