James Quarry, Naracoorte (Miocene of Australia)

Where: South Australia, Australia (37.0° S, 140.8° E: paleocoordinates 47.7° S, 138.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Naracoorte Limestone Member (Gambier Formation), Burdigalian (20.4 - 16.0 Ma)

• N6/N7 planktonic foraminifera biozones

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, shelly/skeletal packstone

• A high abundance of cibicidiids and other middle to outer shelf foraminifers suggests that the Gambier carbonates largely accumulated at 50–150 m (Li et al. 2000). Environment interpreted to be inner and middle shelf by White (1995). It is possible that the Naracoorte Limestone is of somewhat shallower depth than the Gambier Limestone sensu stricto, given the presence of larger foraminifera and large, warm-water molluscs and echinoids.
• Calcarenite containing numerous bivalves, large foraminifers, and gastropods.

Size class: macrofossils
