Time
| Period: | Jurassic | Epoch: | Late Jurassic |
| Stage: | Oxfordian | 10 m.y. bin: | Jurassic 5 |
| Key time interval: | Middle Oxfordian | ||
| Age range of interval: | 161.5 - 154.8 m.y. ago | ||
| Age estimate: | 162.6 ± 1.1 Ma (U/Pb) |
Stratigraphy
| Geological group: | Injune Creek | Formation: | Walloon Coal Measures | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 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 | |||||
Lithology and environment
| Primary lithology: | fine,ferruginous lithified calcareous sandstone | ||
| Secondary lithology: | concretionary argillaceous ironstone | ||
| Includes fossils? | Y | ||
| Includes fossils? | Y | ||
| Lithology description: "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. | |||
| Environment: | "floodplain" | Tectonic setting: | cratonic basin |
| Geology comments: "fresh-water deposits", also described as an "intracratonic flood plain" | |||
