Leangbukta, 55-70 meters above base of member (Silurian of Norway)

Where: Asker, Norway (59.8° N, 10.5° E: paleocoordinates 25.8° S, 8.9° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Lituigraptus convolutus graptolite zone, Leangen Member (Solvik Formation), Aeronian (440.8 - 438.5 Ma)

• bed-level stratigraphic resolution

Environment/lithology: marine; mudstone and shale

• "The lower range...is near the lower limits of the transition zone, and the rest of it is probably deposited entirely within the transition zone...The bioclasitc beds and fine sst interbeds interpreted as storm events...very high frequ. of storm events indicates shallow conditions...upper range of BA 4 into 3...degree of transport minimal."
• The type sequence consists of mudstone interbedded with very abundant, thin coquinas and fine sandstones. The upper beds contain more shale

Size class: macrofossils

Preservation: cast

Collection methods: At PMO.
