Where: Queensland, Australia (24.5° S, 148.3° E: paleocoordinates 59.7° S, 141.1° E)

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

• Assigned to Pseudostrophalosia crassa--Echinalosia deari brachiopod zones and lower APP5 palynomorph zone by Briggs (1998). APP5 palynomorph zone ranges from mid-Wuchiapingian through Changhsingian based on radiometric constraints (Laurie et al., 2016), but this formation constrained to the Wuchiapingian by radiometric dates in the Black Alley shale of 254.32 Ma and 254.08 Ma (Metcalfe et al., 2015) and Phillips et al., 2018).

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; lithified siliciclastic sediments
