Strophodonta colongensis Community, Early Pridolian, N. Urals (Silurian of Russian Federation)

Where: Russian Federation (60.0° N, 60.0° E)

• Paleocoordinates: 24.5° N, 37.1° W (Wright 2013)

• coordinate based on political unit

• local area-level geographic resolution

When: Pridoli (422.7 - 419.6 Ma)

Environment/lithology: marine; gray, argillaceous limestone and marl

• "Interbedding of communities suggests similar BA position...Community interpreted as quiet water, soft, level bottom unit near BA 2-3 boundary in agreement with associated fossils."
• "Occurs chiefly as articulated specimens in several thin interbeds, 5-15 cm thick, of dark gray, commonly argillaceous limestone, interbedded with thin marl, argillaceous shale, and dark brown, fine-grained sandstones and thicker dark gray limestones containing Atrypoidea prunum gigas Community."
