Western Mining Corporation, Cataby (Pleistocene of Australia)

Where: Western Australia, Australia (30.7° S, 115.5° E: paleocoordinates 32.1° S, 114.8° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Ascot Formation, Gelasian (2.6 - 1.8 Ma)

• "Late Pliocene". Age based on molluscan correlations to other units (presence of Hartungia and Cucullaea in lower layers). Planktonic foraminifers from the base of Paulik's bore, Jandakot (Mallett, 1982) included specimens considered to represent the evolutionary transition from Globorotalia tosaensis to early forms of G. truncatulinoides, for which a Late Pliocene age is widely recognized (Kendrick et al., 1991). G. truncatulinoides subsequently immigrated into the Indian and Atlantic oceans between 2.3 and 1.9 Ma, according to Spencer-Cervato & Thierstein (1997), or appeared around 1.9 Ma (Wade et al., 2011), formerly late Pliocene but now early Pleistocene.

• group of beds-level stratigraphic resolution

Environment/lithology: shoreface; lithified, calcareous sandstone

• Neritic inner shelf
• Fine to very coarse, grey to yellow-brown quartz sands with subordinate carbonate and less frequently quartzose calcarenites. Described as "indurated to friable" and categorized here as lithified based on fossil preservation.

Size class: macrofossils

Reposited in the WAM
