Where: New South Wales, Australia (30.8° S, 150.4° E: paleocoordinates 33.7° S, 143.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Pericyclus princeps ammonoid zone, Namoi Formation, Hastarian to Hastarian (358.9 - 346.7 Ma)

• from a "rich fossiliferous bed" in the Namoi Formation, well above the Tulcumba Sandstone and Rangari Limestone "that has been referred to as the Schellwienella cf. burlingtonensis Fauna" that is "age equivalent" to the Pericyclus princeps Zone = Pericyclus Stufe or stage; it is "late Hastarian to earliest Molinacian" (= Ivorian) and older than Chadian according to Roberts et al. 1993

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified siltstone

Size class: macrofossils

Preservation: mold/impression

Collection methods: chemical, mechanical, hydrochloric,

• specimens were "removed by boiling for a short time in concentrated hydrochloric acid, or by treatment with an Airbrasive machine. Latex casts have been made from the moulds"
