Stratigraphy
Geological group:Newcastle Coal Measures
Stratigraphy comments: Likely only three or four feet above the Dirty Seam of the Newcastle Series of coal seams, but possibility that fossil came from higher up in the sequence from the Burwood coal seam horizon, which is one hundred to one hundred and twenty feet above the dirty coal seam. The Dirty Seam is dated as Wuchiapingian, as Metcalf et al. (2015) dated the overlying Nobbys Tuff at 255.26 +/- 0.07 Ma and 255.02 +/- 0.03 Ma.
Lithology and environment
Primary lithology:red or brown lithified mudstone
Lithology description: The material in which the fossils occur is of a bright brick-red colour and very hard, reminding one of the bricks made by the Romans and used by them in ancient Roman buildings in England. The materila has a shallow conchoidal fracture, for the most part very smooth." (Tillyard, 1921)
Environment:terrestrial indet. Tectonic setting:foreland basin
Geology comments: Switch to contractional deformation in Hunter-Bowen orogeny occurred c. 265 Ma; Sydney basin transitioned into foreland basin
Taphonomy
Modes of preservation:mold/impression
