Ballingoole Ls., Bowan Park Subgroup, west flank of Molong Volcanic Belt (Ordovician of Australia)

Where: New South Wales, Australia (33.1° S, 148.9° E: paleocoordinates 16.2° N, 176.6° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Downderry Limestone Member (Ballingoole Limestone Formation), Eastonian (452.7 - 449.5 Ma)

• late Eastonian

• member-level stratigraphic resolution

Environment/lithology: lithified grainstone

• "... interpreted as representing channel deposits at the proximal ends of submarine valleys. These presumably supplied shelf-edge clasts incorporated with lithified periplatform sediments to form the carbonate breccia deposits at the base and top of the Malongulli Formation on the downfaulted eastern side of the MVB."
• calcarenite

Size class: macrofossils
