UQ L4587, quarry along highway north of Theodore, Bowen Basin (Permian of Australia)

Where: Queensland, Australia (24.9° S, 150.1° E: paleocoordinates 59.9° S, 144.5° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Echinalosia ovalis brachiopod zone, Lower Member (Flat Top Formation), Wuchiapingian (259.9 - 254.2 Ma)

• Assigned the Echinalosia ovalis zone of Briggs (1998) and the middle part of palynomorph zone APP5. Laurie et al. (2016) calibrated the APP5 zone to mid-Wuchiapingian through Changhsingian. Phillips et al. (2018) marked the Platypus Tuff bed (dated as 256.01 Ma in Metcalf et al., 2015) within the Flat Top Formation but suggested that the top of the formation was 255.13 Ma based on correlation with a tuff bed at the top of the Colinlea Sandstone equivalent. These constraints suggest a Wuchiapingian age for the Flat Top Formation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified siliciclastic sediments

Size classes: macrofossils, mesofossils

Preservation: cast

Reposited in the UQ

• University of Queensland (UQF)
