O32/f9529 [Okarahia Sandstone] (Cretaceous of New Zealand)

Also known as S56/f529; GS9834

Where: New Zealand (42.6° S, 173.5° E: paleocoordinates 64.7° S, 144.1° W)

• coordinate based on unpublished field data

• outcrop-level geographic resolution

When: Okarahia Sandstone Formation, Piripauan (85.8 - 83.5 Ma)

• STRATIGRAPHIC RELATIONS: From the Okarahia Sandstone, which unconformably overlies Torlesse Supergroup, and is conformably overlain by the Tarapuhi Grit. AGE: Piripauan (=Coniacian-Santonian), on the basis of macrofossil biostratigraphy. STRATIGRAPHIC POSITION: From bed of unknown position within formation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified, fine, shelly/skeletal sandstone

• ENVIRONMENT: Marine deposition under moderate energy conditions, probably not far from shore and at medium to shallow depths.
• SPECIFIC LITHOLOGY: Very fine-fine shely sandstone. LITHIFICATION: Lithified, based on facies description (FRED).

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Warren in 1967; reposited in the IGNS

Collection methods: surface (in situ),

• COLLECTOR: G. Warren, 1967. REPOSITORY: GSNZ (now GNS Science, Lower Hutt, New Zealand).
