Where: Queensland, Australia (25.1° S, 150.2° E: paleocoordinates 60.2° S, 144.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

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

• Upper part of Barfield Formation.

•The Barfield Formation ranges from the Echinalosia wassi-E. deari brachiopod zones of Briggs (1998), correlated with the top of APP4.2, APP4.3, and the lower part of APP5 palynomorph zones. Radiometric calibration of these palynological zones by Laurie et al. (2016) suggests that APP4.3 is mid-Wuchiapingian and APP5 spans the late Wuchiapingian and Changhsingian. A Wuchiapingian age is assigned to the Barfield Formation here.
