Where: New South Wales, Australia (32.7° S, 151.2° E: paleocoordinates 68.0° S, 158.4° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Mulbring Formation, Wordian (266.9 - 264.3 Ma)

• Correlative with the Berry and Broughton Formations, and assigned to the Echinalosia runnegari and E. wassi brachiopod zones by Briggs (1998), and to the APP4.2 palynomorph zone. The APP4.2 zone has its inferred base (266.8 Ma, according to calibrations in Laurie et al., 2016) nearly coincident with the base of the Wordian (266.9 in Wu et al., 2020), and ranges to the early Wuchiapingian. A sample 2 m below the top of the Broughton Formation yielded a radiometric date of 263.51 Ma, within the basal Capitanian (Metcalf et al., 2015), so the a Wordian age is assigned.
