Loder's Creek (W.B. Clarke coll) (Permian of Australia)

Where: New South Wales, Australia (32.6° S, 151.3° E: paleocoordinates 67.9° S, 158.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Muree Formation, Wordian (268.8 - 265.1 Ma)

• Assigned to the Echinalosia robusta/hanloni brachiopod zone and lower APP4.2 palynomorph zone by Briggs (1998). Laurie et al., (2016) inferred an age of 266.8 Ma for the base of APP4.2 on the basis of radiometric constraints, which places it coincident with the base of the Wordian (266.9 Ma in West Texas; Wu et al., 2020).

• group of beds-level stratigraphic resolution

Environment/lithology: marine; lithified siliciclastic sediments

Size class: macrofossils

Collected by W.B. Clarke

• Collected by the Rev. W.B. Clarke and sent to Prof. Sedgwick
