GS4533, Arthurton (F45/f9546) (Permian of New Zealand)

Where: New Zealand (46.1° S, 169.1° E: paleocoordinates 76.1° S, 174.4° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Plekonella multicostata brachiopod zone, Arthurton Group, Wuchiapingian (259.9 - 254.2 Ma)

Environment/lithology: marine; lithified siltstone and lithified mudstone

• The Arthurton facies approached those of normal shelf carbonates so common in the Northern Hemisphere, with quiet conditions of steady accumulation of silt and calcilutite, interrupted by brief standstills.
• As a rule the sediment consists of calcareous siltstone and mustone, locally skeletal micrites, with numerous atomodesmid prisms, interleaved with fenestellid Bryozoa to varying degrees.

Size class: macrofossils

Preservation: cast, mold/impression
