Where: Queensland, Australia (20.8° S, 148.0° E: paleocoordinates 56.0° S, 140.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Upper part of Middle Bowen Beds (Unit C). Upper part of the Blenheim Formation 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.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils
