Late Pleistocene, north side of oil well B35A (Pleistocene of Australia)

Also known as Loc. 22 (McNamara and Kendrick 1994)

Where: Western Australia, Australia (20.8° S, 115.3° E: paleocoordinates 29.3° S, 110.8° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Late/Upper Pleistocene (0.1 - 0.0 Ma)

• STRATIGRAPHIC RELATIONS: From unnamed formation. Late Pleistocene deposits unconformably overly Miocene rocks of the Poivre Fm. THICKNESS: 2 m thick in places. AGE: First determined to be Pleistocene by Smith (1962); no justification stated in text for assignment to Late Pleistocene. STRATIGRAPHIC POSITION: Not stated in text.

• bed-level stratigraphic resolution

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

• ENVIRONMENT: Mosaic of sand, coral and seagrass, inshore shallow waters, moderate to low wave energy and good tidal circulation, water depth unlikely to exceed 5 m.
• SPECIFIC LITHOLOGY: Rubble of shelly limestone with abundant coralline material. LITHIFICATION: Lithified, as stated in text to be "well-cemented" and "rubble".

Size class: macrofossils

Preservation: original aragonite, original calcite

Collection methods: quarrying,

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