Creek outcrop in a braid of the Flinders River on Bezuma Downs Stations (Cretaceous of Australia)

Where: Queensland, Australia (20.0° S, 141.0° E: paleocoordinates 51.0° S, 128.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Toolebuc Formation, Late/Upper Albian (105.3 - 99.6 Ma)

• Late Albian age is based on ammonites and nannofossils. Not older than the Prediscosphaera columnata Zone and not younger than the Mortoniceras inflatum Zone

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; poorly lithified, shelly/skeletal claystone

• oxygen-deficient environment
• finely interlayered organic-rich shales and shell beds are typical of the Toolebuc Formation, resulting in a distinctively black-and-white, thinly-bedded to laminated rock.

Size class: macrofossils

Preservation: trace

Collection methods: bulk, core,
