Ust-Pinega Fm., Russia - Ivantsov and Grazhdankin 1997 (Ediacaran of Russian Federation)

Where: Russian Federation (64.4° N, 40.7° E: paleocoordinates 62.1° S, 23.0° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Ust-Pinega Formation, Ediacaran (635.0 - 541.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: submarine fan; lithified, graded sandstone and lithified siltstone

• Fine-grained sandstones and aleurolites with gradational bedding type, comprising isolated turbidite-like layers with erosional basal surfaces and wavy tops. Interbedded aleurolites and clays are attributable to distal parts of turbid flows. Clays with thin layers of aleurolite grade into aleurolites and clays and presumably resulted from turbid flow activity as well.

Size class: macrofossils

Preservation: cast, trace, replaced with silica
