Where: Queensland, Australia (28.5° S, 150.3° E)
• Paleocoordinates: 74.0° S, 139.0° E (Wright 2013)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Echinalosia preovalis brachiopod zone, Back Creek Group, Wuchiapingian (259.9 - 254.2 Ma)
• Presence of Echinalosia ovalis suggests an age within the E. ovalis 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.
