Where: Russian Federation (71.0° N, 58.0° E: paleocoordinates 6.0° N, 0.8° W)

• coordinate estimated from map

• basin-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

• Occurs in Kamenka Bay Horizon in southern Novaya Zemlya, Seversale Beds of Dolgi Island, and Vaigach Horizon (Units II and III) of Vaigach Island.

• "Deposition took place in quiet water (shells mostly articulated) in a shallow subtidal or intertidal environment, assigned here to BA 2."
• "Occurs in closely interbedded, thinly laminated algal carbonates, ostracode biomicrites, dolomites, and more massive, more banded, variegated argillaceous, silty carbonates."
