Belmont (Pincombe 1922 coll) (Permian of Australia)

Where: New South Wales, Australia (33.0° S, 151.7° E: paleocoordinates 66.5° S, 144.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Belmont Conglomerate Member (Croudace Bay Formation), Changhsingian (254.2 - 252.2 Ma)

• 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).

• bed-level stratigraphic resolution

Environment/lithology: pond; lithified, tuffaceous chert

• 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.

Size classes: macrofossils, mesofossils

Preservation: mold/impression
