Ericmas Quarry (Oligocene of Australia)

Where: South Australia, Australia (31.1° S, 140.1° E: paleocoordinates 46.0° S, 136.0° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Namba Formation, Late/Upper Oligocene (28.4 - 23.0 Ma)

• Eric's Local Fauna. The Ericmas LF derives from fluvial sands deposited in channels cut into the lacustrine units of the Namba Formation, so is younger than the Pinpa LF, and derives from Ericmas Quarry and South Prospect Quarries at Lake Namba a few kilometres south of Lake Pinpa (Tedford et al. 1977; Rich et al. 1991). There is much overlap of species composition between Pinpa and Ericmas LFs suggesting broad similarity in age. 26–24 Ma

Environment/lithology: lacustrine - large; mudstone

Size class: macrofossils
