Poletti's Bore (Pleistocene of Australia)

Where: Western Australia, Australia (32.1° S, 115.9° E: paleocoordinates 32.8° S, 115.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Ascot Formation, Calabrian (1.8 - 0.8 Ma)

• "Early Pleistocene". Age based on molluscan correlations to other units (absence of Hartungia and Cucullaea). Upper part of Ascot Formation contains more extant molluscan species than lower part and lacks some species found in "Late Pliocene" (actually Gelasian) units such as the Roe Calcarenite. With the reassignment of the Gelasian to the Pleistocene, this part of the unit is presumably Calabrian.

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; 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

Collection methods: core
