Sample K2, Section Hill, Cardabia Station (Cretaceous of Australia)

Where: Western Australia, Australia (23.0° S, 114.1° E)

• Paleocoordinates: 53.9° S, 114.9° E (Wright 2013)

• coordinate stated in text

• outcrop-level geographic resolution

When: Korojon Formation, Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• Korojon Formation is uppermost Campanian-Lower Maastrichtian, but based on foraminiferal content the succession in all investigated outcrops is considered to be of Early Maastrichtian age.

• bed-level stratigraphic resolution

Environment/lithology: offshore ramp; bioturbated chalk

• Proximal, open marine-ramp setting, well inboard from the shelf margin. Deposition took place in a comparatively low-energy environment which, based on the foraminifera, is estimated to have been at around 100‒150 m depth
• Horizontally bedded chalks, the notable but variable content of inoceramid skeletal prisms giving it a sandy appearance

Size class: macrofossils

Reposited in the WAM

• Repository: Western Australian Museum (WAM); Edward de Courcy Clarke Earth Science Museum at the University of Western Australia (UWA)
