Mangahouanga Stream, Te Hoe River (Cretaceous to of New Zealand)

Where: New Zealand (38.9° S, 176.8° E)

• Paleocoordinates: 54.9° S, 157.0° W (Wright 2013)

• coordinate stated in text

• small collection-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

Collection methods: surface (float),
