Where: Queensland, Australia (21.1° S, 148.2° E: paleocoordinates 56.3° S, 140.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Pseudostrophalosia crassa brachiopod zone, Blenheim Formation, Wuchiapingian (259.9 - 254.2 Ma)

• Presence of Pseudostrophalosia crassa suggests an age within the P. crassa zone, correlated with the middle part of APP5 palynomorph zone (Briggs, 1998). The APP5 zone was constrained as mid-Wuchiapingian through Changhsingian age by U-Pb dating in Laurie et al. (2016). However, overlying units in the Fort Cooper Coal Measures yield latest Wuchiapingian U-Pb ages (Phillips et al., 2018), constraining the upper Blenheim Fm to Wuchiapingian.
