Where: Western Australia, Australia (20.7° S, 115.4° E: paleocoordinates 29.2° S, 110.9° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Poivre Formation, Middle Miocene (16.0 - 11.6 Ma)

• STRATIGRAPHIC RELATIONS: Miocene rocks of the Poivre Fm overly Eocene rocks with a transgressive unconformity. THICKNESS: As thick as 29 m. AGE: Originally determined to be Early Miocene by Glaessner (in McWhae and Parry, 1954), since refined to be Middle Miocene in age (Caproniere 1975; McNamara and Kendrick 1994). STRATIGRAPHIC POSITION: Not stated in text.

• group of beds-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, shelly/skeletal, red, sandy, calcareous limestone

• ENVIRONMENT: Very shallow water, calcareous, soft sandy substrates.

The Poivre Fm shows pronounced vertical changes in lithology, ranging from brown, yellow to pink limestone, classified as calcarenites of fine or coarse grain-size. LITHIFICATION: Lithified, stated in text to be "hard limestone"

Size class: macrofossils

Preservation: cast, mold/impression, original calcite, replaced with calcite

Collection methods: quarrying,

Taxonomic list

• COMPLETENESS: Exhaustive for gastropoda, bivalvia and echinoidea, although the fauna is probably depleted through poor preservation and requires further collecting. Foraminifera mentioned to be present, but not listed. NOMENCLATURE: Authoritative publication, though poor preservation precludes description of many new forms, and assignment of species names.
