N111/f540 - Tongariro (Landon Series) (Oligocene of New Zealand)

Also known as GS 6062

Where: New Zealand (39.0° S, 175.5° E: paleocoordinates 49.1° S, 179.1° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Oligocene (33.9 - 23.0 Ma)

• Of the Landon series, no formal lithostratigraphic determination. Landon age (early Oligocene to earliest Miocene). The Landon series unconformably overlies Mesozoic greywacke and argillite, and is overlain, unconformably by greywacke conglomerates of the Taranaki series. At Wainone Stream, limestone is not present, and greensand overlies fossiliferous mudstone and coal measures, which rest on greywacke. Greensands and mudstones close to Taurewa Fault dip about 50° to the south-east.

• bed-level stratigraphic resolution

Environment/lithology: offshore; shelly/skeletal mudstone and green sandstone

• Shallow-water siliciclastic environment.
• Fossilifeous mudstone and greensand.

Size class: macrofossils

Collection methods: Collected by Gregg et al. (N.Z. Geo. Surv.) Collections probably reposited in IGNS (USGS) collections.
