Mt. Sandiman Station, 1 km from type section mesa (Eocene of Australia)

Where: Western Australia, Australia (24.3° S, 115.2° E: paleocoordinates 47.9° S, 100.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Merlinleigh Sandstone Formation, Lutetian (47.8 - 41.3 Ma)

• From the presence of foraminifers Maslinella chapmani Glaessner and Wade, Operculina sp., Crespinina kingscotensis Wade and Rotalia sp., Cockbain (1981) confirmed a Late Eocene age for the Merlinleigh Sandstone, correlated in part with the Late Eocene Giralia Calcarenite of the Carnarvon Basin. Giralia Calcarenite later assigned Middle Eocene (Lutetian) age, Zone P12 of Berggren & Miller (1988).

• group of beds-level stratigraphic resolution

Environment/lithology: shoreface; poorly lithified sandstone

• Poorly cemented, silicified quartz sandstone with subordinate siltstone and conglomerate

Size class: macrofossils

Preservation: mold/impression, replaced with silica

Collected by T.A. Darragh, G.W. Kendrick, K.J. McNamara in 1979; reposited in the WAM
