UQ L5159, Macleans Point, St. Georges Basin (Permian of Australia)

Where: New South Wales, Australia (35.1° S, 150.6° E: paleocoordinates 70.1° S, 162.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Echinalosia maxwelli brachiopod zone, Wandrawandian Formation, Roadian (272.3 - 268.8 Ma)

• Brachiopods suggest the upper Echinalosia maxwelli zone, correlated with the APP3.3 palynomorph zone (Briggs, 1998). There are no direct radiometric constraints on APP3.3, although the top of the underlying APP3.2 is around 271.6 Ma (Laurie et al., 2016), placing it near the Kungurian-Roadian boundary or in the lower Roadian. Strata in Western Australia assigned to APP4.1 yielded U-Pb ages of 269.25 Ma or younger, constraining the upper boundary of APP3.3 to the late Roadian. As a result, APP3.3 appears to fall entirely within the Roadian.
