Where: New South Wales, Australia (35.4° S, 150.5° E: paleocoordinates 70.4° S, 162.3° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Wandrawandian Formation, Roadian (272.3 - 268.8 Ma)
• Brachiopods suggest the Echinalosia davidi or E. discinia zone, correlated with the upper part of APP3.3 to APP4.1 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. The top of APP4.1 is likely late Wordian, constrained by earliest Capitanian radiometric dates in the lower part of APP4.2 (Laurie et al., 2016). The Broughton Formation, higher in the Sydney Basin succession, also yields an early Capitanian radiometric date (262.51 Ma) from its uppermost part (Metcalfe et al., 2015). Therefore upper parts of the formation are possibly early Wordian in age, but a Roadian age is assigned in the Ulladulla area.
