S127/f526 - Otekaike Limestone, E. of Trig N (Oligocene of New Zealand)

Also known as GS3907; Coll# 3065 (Hendy PhD)

Where: New Zealand (44.8° S, 170.5° E: paleocoordinates 51.0° S, 175.0° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Otekaike Limestone Formation (Otiake Group), Late/Upper Oligocene (28.4 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From Otekaike Limestone, which is the upper unit of the Otiake Group, overlying the Kokoamu Greensand, and is overlain by the Gee Greensand of the Kaierero Group. AGE: Duntroonian-Waitakian in text of Gage (1957), but largely Waitakian in Table 3; Waitakian = Late Chattian-early Aquitanian; hereby assigned a Late Oligocene age in ensure collection is not orphaned. STRATIGRAPHIC POSITION: Unknown position within formation.

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, calcareous limestone

• ENVIRONMENT: Shallow marine, carbonate.
• SPECIFIC LITHOLOGY: Limestone, highly calcareous. LITHIFICATION: Lithified, largely assumed, as no indication is given text of lithification state, although text says unit is cliff forming and highly calcareous, and limestone.

Size class: macrofossils

Reposited in the IGNS

Collection methods: quarrying,

• COLLECTOR: Unknown collectors. REPOSITORY: New Zealand Geological Survey (now GNS Science, Lower Hutt, New Zealand).
