Dayia minor-Isorthis canaliculata-Lioclema exile Comm., SW Byelorussia (Silurian of Belarus)

Where: Belarus (52.0° N, 24.0° E: paleocoordinates 17.0° S, 3.8° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Pridoli (423.0 - 419.2 Ma)

• Upper Mukhavets Subformation and Kustin Formation.

Environment/lithology: marine; dolomitic, shelly/skeletal marl and dolomitic, shelly/skeletal shale

• "Similar to Skala Horizon assemblages of Podolia, whic are high diversity unites dominated by corals. Similar Pridolian assemblages...in slope facies of Kuressaare and Kaugatuma stages of Baltic region. BA 3."
• "Occurs in marl and shale with laminae of marlstone nodules and lenses (Upper Mukhavets Subformation), grading into the homogeneous, dolomitic marls and shales of the overlying Kustin Formation." [shells in coquinas]

Collection methods: core

• Abundances given for dominant brachiopods and bryozoans.
