Balcombe Bay (Miocene of Australia)

Also known as Assemblage 11; FL 78

Where: Victoria, Australia (38.2° S, 145.0° E: paleocoordinates 47.0° S, 143.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: M6-7 foram zone, Fyansford Formation, Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From Fyansford Fm, which locally overlies the Gellibrand Fm. Stratigraphy is discussed by Gostin (1966). AGE: The age of the assemblage is Middle Miocene and is Balcombian. STRATIGRAPHIC POSITION: From restricted thickness of strata (shore cut platform) within unknown part of formation. The Balcombian encompasses the M6-M7 Foram Zones

• group of beds-level stratigraphic resolution

Environment/lithology: marine; unlithified, shelly/skeletal, gray siltstone

• ENVIRONMENT: Environment not reported in text, siliciclastic.
• SPECIFIC LITHOLOGY: Richly fossiliferous grey silt. LITHIFICATION: Assumed unlithified on the basis of age and figured specimens (Beu and Darragh 2001).

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.
