Shore 1 km SW of Brantevik, section 2, bed F [Alum Shale Fm] (Cambrian of Sweden)

Also known as SSF 8.7

Where: Sweden (55.5° N, 14.3° E: paleocoordinates 42.6° S, 30.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Exsulans Limestone Formation, Lenian (516.0 - 510.2 Ma)

• STRATIGRAPHIC RELATIONS: From the Alum Shale, which overlies the Gislöv Fm. AGE: Lenian, on the basis of trilobite biostratigraphy; Ptychagnostus gibbus trilobite zone. STRATIGRAPHIC POSITION: From bed F in local stratigraphic section. PJW: This is now considered to be Exsulans Limestone.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, phosphatic, gray, calcareous grainstone

• ENVIRONMENT: Marine siliciclastic setting.
• SPECIFIC LITHOLOGY: Massive, medium-dark grey, phosphatic biocalcarenite. LITHIFICATION: Lithified on the basis of figured specimens and facies descriptions.

Size classes: macrofossils, mesofossils

Preservation: replaced with phosphate

Collected by Bergstrom & Ahlberg

Collection methods: bulk, surface (in situ), acetic,

• COLLECTORS: Presumably the authrors, Bergstrom and Ahlberg, c. 1980's. REPOSITORY: Sveriges geologiska undersökning (SGU), Tunavägen, Sweden. METHODS: Majority of fossils obtained by etching of rocks in 10% acetic acid.
