Where: Queensland, Australia (22.4° S, 147.9° E: paleocoordinates 57.6° S, 140.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Back Creek Group, Wuchiapingian (259.9 - 254.2 Ma)

• From the Big Strophalosia zone or Clarkei bed. Both likely belong to the Pseudostrophalosia clarkei zone of Briggs (1998), which is correlated with 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).

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils

Collection methods: Repository: Commonwealth Palaeontology Collection
