Olenidsletta Mbr, Valhallfonna Fm - Ny Friesland, Spitsbergen (Ordovician of Norway)

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

• coordinate estimated from map

• outcrop-level geographic resolution

When: Olenidsletta Member (Valhallfonna Formation), Arenig (478.6 - 466.0 Ma)

• STRATIGRAPHIC RELATIONS: From Olenidsletta Mbr within the Valhallfonna Formation, which is overlain by the Profilbekken Mbr (same fm). AGE: Areginian; Didymograptus hirundo graptolite zone. STRATIGRAPHIC POSITION: 90-100 m above the base of the Olenidsletta Member. PJW: This member is not in the hirundo graptolite zone! There is not hirundo aged rock in this sequence.

•JA: reassigned to the Darriwilian on the assumption that the D. hirundo zone is the British Expansograptus hirundo zone

• 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: macrofossils

Preservation: original phosphate

Collection methods: COLLECTOR: Presumably collected by Fortey and Brunton. REPOSITORY: Sedgewick Museum, Cambridge U.K.).
