Level 2, Yorga Beds, Mezen' Fm., Russia - Ivantsov 1999 (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

When: Mezen' Formation, Ediacaran (635.0 - 541.0 Ma)

• Encompasses the Vendian Period. The unit containing the Y. waggoneri specimens lies at the base of the ""Fifth Cyclite"" or slightly above the base of the Yorga Beds. The imprints occur completely on the bottom of beds. Level 2: This level is stratigraphically slightly higher than Level 1 and corresponds to the base of the lense like sandstone bed. The beds' thickness is about 0.10m and can be traced 200-300m.

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified siltstone and lithified shale

• aleurolite-shale alternation, which include numerous lenses of fine-grained sandstone.

Preservation: cast, replaced with silica, replaced with pyrite

Collection methods: bulk,
