Stratigraphy
| Formation: | Chinchilla Sand | ||||
| Stratigraphy comments: Although no direct dates have been obtained for this deposit, biocorrelation suggests the deposit is early to middle Pliocene (Tedford et al. 1992, Mackness et al. 2000). |
Lithology and environment
| Primary lithology: | ferruginous,quartzose lithified calcareous sandstone |
| Secondary lithology: | poorly lithified silty,sandy claystone |

| Includes fossils? | Y |
| Lithology description: The Chinchilla Sand includes well-lithified calcareous sandstones grading into siltstone and conglomerate (quartz and ferruginous sandstone), and weakly consolidated sands that grade into silt and sandy clay. Such sediments were derived from erosion of the Orallo Formation and its lateritized profiles (Bartholomai & Woods, 1976). | |
| Environment: | alluvial fan |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | mesofossils |
