Eurombah Creek, Durham Downs (Jurassic of Australia)

Also known as Taloona Station

Where: Queensland, Australia (26.1° S, 149.1° E: paleocoordinates 67.0° S, 93.4° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Walloon Coal Measures Formation (Injune Creek Group), Early/Lower Oxfordian (161.2 - 155.7 Ma)

• U-Pb detrital zircon maximum depositional age determined is 162.6 ± 1.1 Ma, no older than early Oxfordian, demonstrating that the fossils are younger than expected, and definitely recovered from the Walloon Coal Measures (Todd et al. 2019)

•originally referred to the Walloon Coal Measures and "Injune Creek Beds", later to Hutton Sandstone

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; lithified, fine-grained, ferruginous, calcareous sandstone and concretionary, argillaceous ironstone

• "fresh-water deposits", also described as an "intracratonic flood plain"
• "the matrix consisted mainly of clay-ironstone, but there was also a closely-investing, fine-grained, calcareous sandstone which acted as a natural cement." Clay is oxidized and concretionary, sandstone is ferruginous.

Size class: macrofossils
