Rostricellula sp. nov.-Pholidostrophia cocksi Comm., Saelabonn Fm., Ringerike Di (Silurian of Norway)

Where: Norway (60.2° N, 10.3° E: paleocoordinates 25.5° S, 9.1° W)

• coordinate based on political unit

• local area-level geographic resolution

When: Saelabonn Formation, Aeronian (440.8 - 438.5 Ma)

• Upper parts of formation. Type locality is in Limovnstangen Mbr.

• member-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal limestone and calcareous siltstone

• "...Hummocky CS [indicates] transition zone into lower shoreface. Thereafter there is an upwards shallowing, which may have led to deosition into the supralittoral zone. Deposition mainly within shoreface, very shallow. Shelf strongly affected by storms and tidal influence secondary. [Based on relation to previous fauna, community is in] BA 2."
• "...most of the fauna found in thin to thick bioclastic beds interbedded with shale and calcareous siltstone. There are numerous sedimentary structures, among others hummocky cross lamination in the lower parts of the sequence."
