Stricklandia lens-Rugose coral Comm., Spirodden Mbr., Solvik Fm. (Silurian to of Norway)

Where: Norway (59.8° N, 10.4° E: paleocoordinates 26.3° S, 9.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Spirodden Member (Solvik Formation), Rhuddanian to Rhuddanian (443.4 - 438.5 Ma)

• Also known from Sylling Mbr. of Saelabonn-Solvik Formation near Toverud Fram in Sylling, Modum District. Latter half of Rhuddanian and slighly into early Aeronian.

• member-level stratigraphic resolution

Environment/lithology: marine; calcareous mudstone and limestone

• "...structures...indicate position above storm wave base, although proximality analysis gives offshore position below normal storm wave base for the Spirodden locality [Interpretation is that community was elevated but offshore]... BA 4."
• "...foun in thick, lime rich mudstone interbedded with thin limestone beds. The structures in rare siltstone interbeds and siltstone-bioclastic couplets indicate position above storm wave base..."

Collection methods: Table 22.18 gives abundance data and forms basis for this list. Several samples are combined in this table. This collection overlaps substantially with PBDB collections 503 and 13844, but it has a more extensive faunal list.
