GSQ L2261, Prospect Creek (Permian of Australia)

Where: Queensland, Australia (24.7° S, 150.5° E: paleocoordinates 59.8° S, 156.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Echinalosia preovalis brachiopod zone, Camboon Formation, Kungurian (279.3 - 272.3 Ma)

• Brachiopods suggest the lower Echinalosia preovalis zone, correlated with the upper APP3.1 palynomorph zone (Briggs, 1998). The APP3.1 zone does not have any radiometric constraints, although the top of the overlying APP3.2 is around 271.6 Ma (Laurie et al., 2016), placing it near the Kungurian-Roadian boundary or in the lower Roadian. Phillips et al. (2018) report ages of 282.72 and 282.41 Ma from strata no older than APP2.2, providing an upper constraint on APP3.1. Phillips et al. (2018) also place APP3.1 in the Kungurian, which is consistent with the presence of the ammonoid Neocrimites in APP3.1 of the Tiverton Formation (although not unequivocal).

• group of beds-level stratigraphic resolution
