Ad24. Bird Rock (Oligocene of Australia)

Also known as PL3024

Where: Victoria, Australia (38.3° S, 144.3° E: paleocoordinates 52.9° S, 142.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Jan Juc Formation, Chattian (28.1 - 23.0 Ma)

• STRATIGRAPHIC RELATIONS: From Jan Juc Fm, which overlies the Demons Bluff Fm (Late Oligocene) and is overlain by the Puebla Fm (Early Miocene). The Jan Juc Fm is laterally contiguous with the Pt Addis and Waurn Ponds Fm. AGE: Late Oligocene according to molluscan biostratigraphy of Darragh and Kendrick (2000) and Beu and Darragh (2001). Fig. 5 of Beu and Darragh (2001), however, indicates the the base of the formation is correlated to the base of the Aquitanian (Early Miocene), while their appendix lists Late Oligocene as the age. Janjukian local stage=Chattian-Aquitanian. STRATIGRAPHIC POSITION: From unknown position within formation.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; lithology not reported

• ENVIRONMENT: Apparently a siliciclastic, shallow marine setting.
• LITHOLOGY: Unknown lithology, not reported in text. LITHIFICATION: Unknown, not reported in text.

Size class: macrofossils

Preservation: original aragonite

Collection methods: Collections are registered in the Western Australia Museum (WAM) and Museum of Victoria (NMV).
