Where: New South Wales, Australia (35.2° S, 150.6° E: paleocoordinates 70.2° S, 162.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Wandrawandian Formation, Roadian (272.3 - 268.8 Ma)

• "Ulladulla Formation." From lower Wandrawandian Formation, Echinalosia maxwelli and E. davidi zone correlative. Upper Echinalosia maxwelli or E. davidi brachiopod zones are equivalent to the middle of the APP3.3 palynomorph zone (Briggs, 1998). Laurie et al. (2016) dated zircons from the Rowan Formation in the Sydney Basin (in the underlying upper Echinalosia preovalis zone, or upper APP3.2) as 271.60 and 271.89 Ma, constraining its upper part to Roadian, given a Roadian-Wordian boundary around 266.9 Ma (Wu et al., 2020). 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 (Laurie et al. 2016). As a result, APP3.3 appears to fall entirely within the Roadian. As a result, the locality is most likely Roadian.
