Redbank Plains (Eocene of Australia)

Where: Queensland, Australia (27.7° S, 152.9° E: paleocoordinates 48.3° S, 153.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Redbank Plains Formation, Ypresian (56.0 - 47.8 Ma)

• Overlying basalts dated at 45 Ma, so no younger than Eocene. Paleocene age is possible but Eocene is most widely accepted.

Environment/lithology: lacustrine - small; lithified, brown, yellow, muddy ironstone

• A shallow, permanent lake with a floor of "mud, decayed vegetable matter and algae"
• The matrix is a dark yellowish brown clay ironstone

Size classes: macrofossils, mesofossils

Preservation: mold/impression

Reposited in the UQ

• Material at University of Queensland (UQF)
