Addiscot Beach - Angahook Fm (Oligocene of Australia)

Also known as Assemblage 6; FL 23

Where: Victoria, Australia (38.4° S, 144.3° E: paleocoordinates 52.9° S, 142.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Angahook Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From Angahook Fm, which regionally conformably overlies the Anglesea Mbr of the Demons Bluff Fm, which in turb may be correlaed with the Browns Creek Clay and the Glen Aire Clay. Stratigraphy is discussed by Raggatt and Crespin (1955). AGE: The age of the assemblage is Late Oligocene and is immediately pre-Janjukuan. STRATIGRAPHIC POSITION: From basal 4 m of the Angahook Fm.

• group of beds-level stratigraphic resolution

Environment/lithology: marine; pyritic, gray, sandy claystone

• ENVIRONMENT: Environment not reported in text, siliciclastic.
• SPECIFIC LITHOLOGY: Dark grey pyritic sandy clay. LITHIFICATION: Unknown lithification.

Size class: macrofossils

Collection methods: COLLECTOR: Probably multiple collectors from same locality, including the author, and combination with existing museum collections. REPOSITORY: Museum of Victoria.
