Stratigraphy
| Formation: | Elderslie | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: Formation primarily belongs to the Echinalosia maxwelli brachiopod zone, equivalent to the upper part of APP3.2 or lower APP3.3 palynomorph zone. 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 E. maxwelli zone is most likely Roadian. | |||||
