Gellibrand Fm - Mouth of Gellibrand River (Miocene of Australia)

Where: Victoria, Australia (38.6° S, 143.3° E: paleocoordinates 50.0° S, 141.3° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Gellibrand Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Gellibrand Fm, which conformably overlies the Clifton Fm (Early Oligocene and is conformably overlain by the Muddy Creek Fm and Port Campbell Limestone (late Middle Miocene). AGE: late Early Miocene and possibly earliest Middle Miocene (Longfordian-Batesfordian) according to Beu and Darragh (2001). STRATIGRAPHIC POSITION: From multiple localities and horizons, hence assigned to a "formation" scale. NOTES: From antiquated publication that predates establishment of region lithostratigraphic framework. Assignments to lithostratigraphic unit and age are based on interpretation by enterer on the basis of cross-referening localities and taxa to more recent publications (e.g. Darragh 1970, Darragh 1986, and in particular Beu and Darragh 2001).

• formation-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, gray, calcareous siltstone

• ENVIRONMENT: Environment not reported in text, presumably shallow marine siliciclastic setting.
• SPECIFIC LITHOLOGY: Grey calcareous silt. LITHIFICATION: Poorly lithified, assumed on the basis of facies description and age.

Size class: macrofossils

Collection methods: COLLECTOR: Unknown collectors, possibly including Tate (1880's). REPOSITORY: South Australia Museum (SAM), Adelaide, Australia.

Taxonomic list

• COVERAGE: Exhaustive list, comprising bivalvia, gastropoda, and scaphopoda. NOMENCLATURE: Very antiquated nomenclature (c. 1880's) with species-level assignments from authoritative publication. Nomenclature updated where possible through recent systematic revisions and checklists (e.g. Darragh, 1970).
