Chasmataspid-Associated Biota of the Zubova Suite, Noril'sk, Siberia (Devonian of Russian Federation)

Where: Russian Federation (69.3° N, 88.1° E: paleocoordinates 21.8° N, 1.4° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Zub Formation, Lochkovian (419.2 - 410.8 Ma)

• Zubova Suite -Upper third of the Zub Horizon

• formation-level stratigraphic resolution

Environment/lithology: marine; gray marl

• "Krylova et al. (1967, p. 479) described the environment as 'extensive, shallow-water, salinized reservoirs'. Underlies the BA 1 fauna of the Kureika Suite. The rock types and Leperditia sound like a hypersaline, BA 1 environment"
