Conchidium orthocephalum Community, Late Ludlow, Central Urals (Silurian of Russian Federation)

Where: Russian Federation (56.5° N, 59.2° E: paleocoordinates 0.7° S, 12.3° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Ludlow (427.4 - 423.0 Ma)

• Possibly also latest part of Early Ludlow.

Environment/lithology: marine; black, gray limestone

• "NO evidence of shell transport..This is a soft, level bottom, quiet water, BA 3 community. This community evolved from the slightly older C. aracaensis reef community, subsequent to the cessation of the reef building process in the Ural-Tian Shan region."
• "Forms small banks in dark gray and black, medium bedded, fine-grained limestones."
