Sample SPP 100-112, Ny Friesland [Profilbekken Mbr, Valhallfonna Fm] (Ordovician of Norway)

Where: Norway (78.9° N, 18.0° E: paleocoordinates 16.0° N, 32.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Profilbekken Member (Valhallfonna Formation), Llanvirn (466.0 - 460.9 Ma)

• STRATIGRAPHIC RELATIONS: From Profilbekken Mbr within the Valhallfonna Formation. AGE: Early Darriwilian (Dal-2) on the basis of well dated radiolarian assemblages from Cow Head and Table Head Groups of western Newfoundland; correlated to latest Arenigian-early Llanvirn. STRATIGRAPHIC POSITION: 185 m above the base of the Valhallfonna Formation.

• member-level stratigraphic resolution

Environment/lithology: marine; lithified, glauconitic, shelly/skeletal, brown, calcareous, cherty/siliceous limestone

• ENVIRONMENT: No environmental data or interpretation provided.
• SPECIFIC LITHOLOGY: Brown calcilutite limestone containing scattered glauconitic grains and silicified fauna. LITHIFICATION: Assumed to be lithified given facies description, age and figured specimens.

Size class: microfossils
