GS 14182, Mangahouanga Stream (V19/f133) (Cretaceous to of New Zealand)

Where: New Zealand (38.9° S, 176.8° E: paleocoordinates 58.8° S, 168.7° W)

• coordinate stated in text

• hand sample-level geographic resolution

When: Tahora Formation, Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)

• Based on the age assigned to the rocks of the surrounding country, determined from molluscan fossils collected from a range of boulders found in the Mangahouanga Stream.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified, fine-grained, concretionary, brown sandstone

• The occurrence of terrestrial fossils in marine sediments suggests that the depositional environment was near-shore, and in moderately shallow water, possibly close to a river, draining a forested hinterland, which brought down substantial quantities of plant material and other terrestrial remains in addition to its normal sediment load.
• The specimen was collected as a small brown coloured, fine-grained spherical concretion, 50 mm in diameter

Size classes: macrofossils, mesofossils

Preservation: mold/impression

Collected by J. Wiffen in 1984; reposited in the IGNS

Collection methods: surface (float),
