Where: Norway (63.1° N, 7.8° E)
• Paleocoordinates: 18.7° S, 63.7° W (Wright 2013)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: D Member, Rhuddanian to Rhuddanian (443.1 - 438.6 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,
