Bolitho Mudstone, Inangahua Outlier, Reefton area, New Zealand (Devonian of New Zealand)

Where: New Zealand (42.1° S, 171.9° E: paleocoordinates 23.1° S, 178.8° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Bolitho Mudstone Formation (Reefton Group), Emsian (407.6 - 393.3 Ma)

• Reefton Group is not very well dated, as there are few correlatable fossils.

• formation-level stratigraphic resolution

Environment/lithology: marine; mudstone and lime mudstone

• "Low energy offshore shelf with sporadic higher energy storm events."
• "120m. Massive, uniform mudstone; siltstone & micritic horizons. Thin, highly fossiliferous shell horizons."
