GSQ D227, Elphinstone-Homevale Road (Permian of Australia)

Where: Queensland, Australia (21.5° S, 148.5° E: paleocoordinates 56.7° S, 141.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Equivalent of S. pelicanensis bed and Pelican Creek fauna. Co-occurrence of Terrakea elongata suggests an age within the P. ingelarensis, or possibly P. clarkei or P. crassa zone (but pelicanensis bed thought to be equivalent to the P. ingelarensis zone), correlated with the lower part of APP5 or possibly the upper part of APP4.3 palynomorph zone (Briggs, 1998). The APP4.3 zone was constrained as mid-Wuchiapingian age by U-Pb dating in Laurie et al. (2016). 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.
