Haughs Quarry (I40/f360) (Oligocene of New Zealand)

Where: South Island, New Zealand (44.7° S, 170.6° E: paleocoordinates 50.9° S, 174.8° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Otekaike Limestone Formation, Duntroonian (27.3 - 25.2 Ma)

• Lower Otekaike Limestone, upper Duntroonian local stage. Planktics lack adults of Globoquadrina dehiscens; this species is the usual indicator of the local Waitakian stage, and is known to occur about 6 m above the billfish horizon. The absence of G. dehiscens and presence of Notorotalia spinosa indicates Duntroonian stage.

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; massive, glauconitic, shelly/skeletal, green, yellow lime mudstone

• The setting is interpreted as below storm wave base and of mid- to perhaps outer shelf depth, given a grain size of very fine sand and the lack of bedding that might result from persistent traction currents.
• The lithology is a light green-yellow massive bioclastic limestone that is slightly glauconitic, slightly quartzose, slightly muddy, and contains occasional macroinvertebrates.

Size class: macrofossils

Preservation: adpression
