Also known as Loc. 1 (McNamara and Kendrick 1994)

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.
• SPECIFIC LITHOLOGY: Hard, pink limestone. GENERAL LITHOLOGY: No specific lithology for this collection. 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,

• COLLECTORS: Collected by authors, K.J. McNamara and G.W. Kendrick. REPOSITORY: Western Australian Museum (WAM)

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.
