Where: Queensland, Australia (20.6° S, 147.9° E: paleocoordinates 57.0° S, 143.4° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Blenheim Formation, Wordian to Wordian (266.9 - 254.2 Ma)

• The stratigraphic position within the formation is unknown, and is possibly not even from the Blenheim Formation. Most of the Blenheim Formation is Wuchiapingian in age, containing brachiopod zones correlated with the upper part of APP4.3 palynomorph zone or 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. However, the Moonlight Sandstone member contains brachiopod zones correlated with APP4.2 palynomorph zone (Briggs, 1998). The APP4.2 zone was constrained as late Wordian to mid-Wuchiapingian age by U-Pb dating in Laurie et al. (2016). In the Sydney Basin, these species are common in the Broughton Formation, dated as older than early Capitanian (a sample 2 m below the top yielded a radiometric date of 262.51 Ma in Metcalf et al., 2015).
