ammonites
Kimble's Hill, Belmont (Knight coll) (Permian of Australia)

Where: New South Wales, Australia (33.0° S, 151.7° E: paleocoordinates 66.8° S, 145.7° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Belmont Conglomerate Member (Croudace Bay Formation), Changhsingian (254.0 - 252.3 Ma)

• Insect bed is 30 cm thick, but insects concentrated approximately 2 cm below top

• bed-level stratigraphic resolution

Environment/lithology: pond; lithified, fine-grained, tuffaceous, gray 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.

Size classes: macrofossils, mesofossils

Preservation: mold/impression
