UQ L4318, Fossil Ridge, Cracow (Permian of Australia)

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

• coordinate estimated from map

• 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).

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified lithology not reported

Size class: macrofossils

Reposited in the UQ
