| Coordinates: | 33.0° South, 151.7° East (view map) | ||
| Paleocoordinates: | 66.5° South, 144.4° East | ||
| Basis of coordinate: | estimated from map | ||
| Geographic resolution: | outcrop |
Time
| Period: | Permian | Epoch: | Lopingian |
| Stage: | Changhsingian | 10 m.y. bin: | Permian 4 |
| Key time interval: | Changhsingian | ||
| Age range of interval: | 254.14000 - 251.90200 m.y. ago |
Stratigraphy
| Formation: | Croudace Bay | Member: | Belmont Conglomerate | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: From horizon 70 feet below base of Fassifern Coal, according to Knight (1950). Fassifern coal dated at 253.38 +/- 0.08 Ma and the underlying Upper Pilot A seam at 253.55 +/- 0.06 Ma by Metcalf et al. (2015). | |||||
Lithology and environment
| Primary lithology: | tuffaceous lithified chert | ||
| Environment: | pond | Tectonic setting: | foreland basin |
| Geology comments: Insect bed appears to have been deposited in shallow ephemeral floodbasin ponds and is stratigraphically positioned between fast-flowing river and coal swamp deposits. Volcanic ash draped the area, infilling the pools and preserving the taphocoenosis. Switch to contractional deformation in Hunter-Bowen orogeny occurred c. 265 Ma; Sydney basin transitioned into foreland basin. | |||
Taphonomy
| Modes of preservation: | mold/impression |
| Size of fossils: | macrofossils,mesofossils |
