Where: Norway (63.1° N, 7.8° E: paleocoordinates 23.4° S, 11.1° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: D Member, Rhuddanian to Rhuddanian (443.4 - 438.5 Ma)
• "Both the fossil content and the lithology are very similar to the age-equivalent Solvik Fm. of the Oslo region." "Both the macrofaunas and the microfossils definitely indicate an early Llandovery (Rhuddanian) age, possibly just extending into the succeeding Aeronian Stage."
• bed-level stratigraphic resolution
Environment/lithology: deep subtidal shelf; lithified shale and limestone
Collection methods: core,
