Tamala Limestone (Stage 7), Perth Basin (Pleistocene of Australia)

Where: Western Australia, Australia (32.0° S, 115.8° E: paleocoordinates 32.0° S, 115.8° E)

• local area-level geographic resolution

When: Tamala Limestone Formation, Middle Pleistocene (0.8 - 0.1 Ma)

• AGE: Extended discussion of age in text (Kendrick et al., 1991), but generally regarded as Middle Pleistocene on the basis of field stratigraphic relationships with younger units of known age, amino acid racemization, ESR data, faunal biostratigraphy and preservation state. STRATIGRAPHIC POSITION: From Oxygen Isotope Stage 7. STRATIGRAPHIC RELATIONS: Kendrick et al. (1991) do not follow convential regional lithostratigraphic treatment of the Quaternary and treat the Tamala Limestone as a formation, containing members, including the Peppermint Grove and Minim Cove Members (also oxygen Isotope Stage 7).

• bed-level stratigraphic resolution

Environment/lithology: estuary or bay; poorly lithified, medium-grained, coarse, shelly/skeletal, calcareous sandstone

• ENVIRONMENT: Accumulated in beach and neashore environments; shallow-marginal seaward part of an estuary with good oceanic exchange.
• SPECIFIC LITHOLOGY: Coarse to medium-grained calcarenite. LITHIFICATION: Presumed to be poorly-lithified given referrals to limestone and "moderate leaching" of aragonitic material.

Size class: macrofossils

Preservation: cast, mold/impression, original aragonite, original calcite

Collection methods: quarrying,

• COLLECTOR: Faunal list is a composite of decades of collecting effort, including that reported by Darragh and Kendrick (1971), Kendrick (1981), Ponder (1985), and Kendrick unpublished data. REPOSITORY: Collection assembled from material reposited in Western Australian Museum (WAM).

Taxonomic list

• COMPLETENESS: Not exhaustive (stated to be selective, presumably on the basis of biogeographic utility of taxa), but certainly comprehensive. NOMENCLATURE: Not an authoritative publication, but nomenclature appears modern with extensive subgeneric and species-level assignments.
