Mangahouanga Stream (V19/f1) (Cretaceous to of New Zealand)

Also known as GS11840

Where: Hawke's Bay, New Zealand (38.9° S, 176.8° E: paleocoordinates 58.9° S, 168.8° W)

• coordinate based on nearby landmark

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

• 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.

Size class: macrofossils

• Isolated teeth, small and recurved, with raised longitudinal ridges on crowns

Preservation: concretion

Collected by W.L. Moisley and J. Wiffen in 1976

Collection methods: quarrying, surface (float), mechanical,
