Where: South Island, New Zealand (42.6° S, 173.5° E: paleocoordinates 58.5° S, 147.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Conway Formation (Eyre Group), Campanian (83.6 - 72.1 Ma)

• New Zealand Stage nomenclature (Warren, 1995) places the Conway Siltstone at Haumuri Bluff in the lower Haumurian. Correlation with global Upper Cretaceous stages places the Haumuri Bluff section in the lower to middle Campanian; these correlations and age assessments are based on the indexing provided by dinoflagellates, inoceramids, and foraminiferans (Roncaglia and Schioler, 1997).

Environment/lithology: foreshore; poorly lithified, massive, bioturbated, gray, sandy siltstone

Size classes: macrofossils, mesofossils

• A broken distal end of a humerus and a complete ulna of Mauisaurus haasti, and Polycotylidae indet. bones (an indeterminate propodium, a cervical centrum, a limb element)

Preservation: concretion
