M28/f90 - Wangapeka Fm, Wangapeka Valley (Ordovician of New Zealand)

Where: New Zealand (41.4° S, 172.6° E: paleocoordinates 9.1° N, 176.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Wangapeka Formation, Hirnantian (445.2 - 443.4 Ma)

• STRATIGRAPHIC RELATIONS: From near top of Wangapeka Formatrion, which is gradationally overlain by the Hailes Quartzite (Pridolian). AGE: Hirnantian age, equivalent to the graptolite zones Bo4 and Bo5 of the Bolindian Stage.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified, gray mudstone

• ENVIRONMENT: No environmental data reported in text.
• SPECIFIC LITHOLOGY: Dark grey mudstone and muddy sandstone. LITHIFICATION: Lithified based on age, tectonic deformation, and description of "internal and external moulds" and "slabs".

Size class: macrofossils

Preservation: cast, mold/impression
