Where: Queensland, Australia (28.4° S, 152.1° E: paleocoordinates 63.2° S, 149.2° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Condamine Formation, Wuchiapingian (259.9 - 254.2 Ma)
• Webster & Jell suggested an Artinskian age on the basis of the crinoid fauna. However, the unit (including brachiopods from Lucky Valley Creek) was assigned to the Echinalosia ovalis and E. voiseyi zones by Briggs (1998), and to mid-APP5 palynomorph zone. Radiometric calibrations of the palynomorph zones by Laurie et al. (2016) indicate a mid-Wuchiapingian to Changhsingian age for the zone. A Wuchiapingian age is assigned to the Condamine Beds, as the correlative brachiopod zones in the Bowen Basin are constrained radiometrically to the Wuchiapingian.
