Where: Queensland, Australia (25.4° S, 150.3° E: paleocoordinates 60.6° S, 156.4° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Echinalosia preovalis brachiopod zone, Dresden Member (Buffel Formation), Kungurian (279.3 - 272.3 Ma)

• Brachiopods suggest the lower Echinalosia preovalis zone, correlated with the upper APP3.1 palynomorph zone (Briggs, 1998). The APP3.1 zone does not have any radiometric constraints, although the top of the overlying APP3.2 is around 271.6 Ma (Laurie et al., 2016), placing it near the Kungurian-Roadian boundary or in the lower Roadian. Phillips et al. (2018) report ages of 282.72 and 282.41 Ma from strata no older than APP2.2, providing an upper constraint on APP3.1. Phillips et al. (2018) also place APP3.1 in the Kungurian, which is consistent with the presence of the ammonoid Neocrimites in APP3.1 of the Tiverton Formation (although not unequivocal).
