BMR B1572, Parrot Creek, Mulgrave Road Crossing (Permian of Australia)

Where: Queensland, Australia (20.8° S, 147.7° E: paleocoordinates 56.0° S, 139.9° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Blenheim Formation, Wuchiapingian (259.9 - 254.2 Ma)

• 500 feet below top of Middle Bowen Marine Series, from the upper part of the Blenheim Subgroup (Dickins 1989). This part of the Blenheim Formation is Wuchiapingian in age, containing brachiopod zones correlated with the upper part of APP4.3 palynomorph zone or - more likely for this collection - lower part of APP5 (Briggs, 1998). The APP4.3 zone was constrained as mid-Wuchiapingian age and APP5 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.
