Solberga quarry, Siljan District [Kallholn Shale] (Silurian of Sweden)

Where: Sweden (61.0° N, 14.5° E: paleocoordinates 23.0° S, 7.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Spirograptus turriculatus graptolite zone, Kallholn Shale Formation, Llandovery (443.4 - 433.4 Ma)

• STRATIGRAPHIC RELATIONS: From the Kallholn Shale, which directly overlies the Boda Limestone. AGE: Llandovery, on the basis of graptolite biozonation. STRATIGRAPHIC POSITION: Exposed in a 5.5m section. In this succession two generations of stromatactis-bearing mudmounds are preserved with their flank deposits and onlapping shales bearing diverse shelly and grap- tolitic faunas

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, black, brown, green shale

• SPECIFIC LITHOLOGY: Greenish to brown and black shales. LITHIFICATION: Lithified, on the basis of facies description and sample preparation techniques.

Size class: macrofossils

• COVERAGE: Exhaustive for radiolaria, but a rich fauna of graptolites, sponge spicules, acritarchs, chitinozoans, and conodonts was found associated with the radiolaria and not reported in this paper.
