Lake Bullenmerri - Fyansford Fm (Miocene of Australia)

Also known as Assemblage 13; FL 87

Where: Victoria, Australia (38.2° S, 143.1° E: paleocoordinates 47.1° S, 141.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Gellibrand Formation, Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: From Gellibrand Fm, which is regionally overlain by the Rutledge Creek Member of the Port Campbell Limestone. Stratigraphy is discussed by Mallet (1977). AGE: The age of the assemblage is late Middle Miocene and is Bairnsdalian. STRATIGRAPHIC POSITION: From limited stratigraphic thickness exposed on lake shore.

• group of beds-level stratigraphic resolution

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

• ENVIRONMENT: Environment not reported in text, siliciclastic.
• SPECIFIC LITHOLOGY: Yellow to blue-grey calcareous silt, moderately rich in molluscs, bryozoans and corals. 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.
