Vikarbyn Section 0.0 - 0.4 m (Ordovician of Sweden)

Also known as Was: Seby Limestone Assemblage, Siljan, Sweden

Where: Siljan, Sweden (60.9° N, 15.0° E: paleocoordinates 33.1° S, 7.9° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Yangtzeplacognathus foliaceus conodont zone, Seby Limestone Formation, Lasnamagi (463.5 - 460.9 Ma)

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, coarse-grained, shelly/skeletal, gray, green, calcareous limestone
