Wilmot River (D39/f031) (Permian of New Zealand)

Where: New Zealand (44.4° S, 168.2° E)

• Paleocoordinates: 64.8° S, 156.7° W (Wright 2013)

• outcrop-level geographic resolution

When: Mantle Volcanics Formation, Sakmarian (293.5 - 290.1 Ma)

• LITHOSTRATIGRAPHY: Mantle Volcanics Formation, within the Brook Street terrane. STRATIGRAPHIC POSITION: Mantle Volcanics Formation is 1300 m thick in this region and fossils were derived from talus boulders in the upper 600 m of the section. AGE: Assigned to the Sakmarian or possibly ?Sterlitamakian based on faunal composition. Previously regarded as Early Permian.

• group of beds-level stratigraphic resolution

Environment/lithology: shoreface; lithified, tuffaceous sandstone

• ENVIRONMENT: Shall shelf, near wavebase, sands and silts, including taxa that tolerate rocky shoreline, proximal sandy shoreface, and distal sandy shoreface. TECTONIC SETTING: No tectonic data reported. SEQUENCE STRATIGRAPHY: No sequence stratigraphic data reported.
• SPECIFIC LITHOLOGY: Very fine sand clinopyroxene and plagioclase crystal-lithic tuff, with isolated outsized lithic and lapilli clasts up to 20 mm in diameter. LITHIFICATION: Lithified, based on description and figured specimens.

Size class: macrofossils

Preservation: mold/impression, recrystallized, replaced with calcite

Collection methods: COLLECTOR: Collected by authors, J.G. Begg and H.R. Ballard, and C.A. Landis. REPOSITORY: Not stated, but almost definately the GNS (Geological Survey of New Zealand) or University of Otago.
