Where: Queensland, Australia (23.4° S, 150.6° E: paleocoordinates 58.6° S, 155.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Berserker Formation, Kungurian (279.3 - 272.3 Ma)

• Brachiopods from other collections at the Lakes Creek quarry suggest the E. warwicki zone, correlated with the lower part of the 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). It is possible that units from the lower part of APP3.1 may be Artinskian.
