Station L487 [Futuna Limestone] (Miocene of Fiji)

Where: Fiji (18.5° S, 178.5° E: paleocoordinates 18.4° S, 178.5° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Futuna Limestone Formation, Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From Futuna Limestone, which overlies the Lau volcanics (?Early-Middle Miocene), and are overlain by the Koro Mbasanga volcanics (?Late Miocene). AGE: Lower Miocene according to Ladd (1945), and stage "f" of Van der Vlerk. Ladd's age is based on lyellian percentages so should be treated with caution. Lad (1966, 1972, 1977, 1982) appear to suggest a Middle Miocene age, which is adopted here. STRATIGRAPHIC POSITION: Basal foraminiferal limestone.

• bed-level stratigraphic resolution

Environment/lithology: lithified limestone

• ENVIRONMENT: Unknown environment, though presumably shallow water carbonate.
• SPECIFIC LITHOLOGY: Foraminiferal limestone. LITHIFICATION: Presumed lithified, as stated to be limestone, hill capping, and with limited diversity.

Size class: macrofossils

Collection methods: COLLECTOR: H.S. Ladd and E.J. Hoffmeister, presumably with others. REPOSITORY: Unknown, possibly the Bernice P. Bishop Museum, Honolulu, Hawaii, or the USNM.
