Madura, 13 km north of Firestick Cave (Eocene of Australia)

Where: Western Australia, Australia (31.7° S, 127.0° E: paleocoordinates 52.2° S, 117.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Wilson Bluff Formation, Priabonian (38.0 - 33.9 Ma)

• An Eocene age was originally suggested for the formation. This has been confirmed by the discovery of the Late Eocene bivalve Notostrea lubra, and Australanthus longianus, an echinoid of the same age. Foraminiferal assemblages suggest that the uppermost part is Late Eocene and the base is Middle Eocene (Li et al., 1996)

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal shelf; lithified, shelly/skeletal, white, cherty/siliceous packstone

• Foraminifer suggest the lower section was deposited in water greater than 76 m deep, whilst the upper section was originally shallower
• The Wilson Bluff Limestone can be best described as a poorly sorted white, compact packestone with bryozoan fragments in lime mud. Chert nodules can be found in all but the lowest 12 m.

Size classes: macrofossils, mesofossils
