GSQ D61, Oxtrack Creek (Permian of Australia)

Where: Queensland, Australia (25.3° S, 150.3° E: paleocoordinates 61.1° S, 151.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Oxtrack Formation, Wordian (266.9 - 264.3 Ma)

• Assigned to the Echinalosia robusta/hanloni brachiopod zone and lower APP4.2 palynomorph zone by Briggs (1998). Laurie et al., (2016) inferred an age of 266.8 Ma for the base of APP4.2 on the basis of radiometric constraints, which places it coincident with the base of the Wordian (266.9 Ma in West Texas; Wu et al., 2020).

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; lithified siliciclastic sediments

Size class: macrofossils

Preservation: mold/impression
