Where: Western Australia, Australia (29.4° S, 127.1° E: paleocoordinates 41.1° S, 121.8° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Colville Sandstone Formation, Early/Lower Miocene (23.0 - 16.0 Ma)
• STRATIGRAPHIC RELATIONS: From Colville Sandstone, which unconformably overlies the Wilkinson Range beds, Ilma neds, and Precambrian metamorphoc rocks in places The Colville Sandstone grades laterally into the Nullabor Limestone, and is overlain by quaternary deposits.

STRATIGRAPHIC POSITION: From base of the exposure.
• bed-level stratigraphic resolution
Environment/lithology: transition zone or lower shoreface; lithified, coarse-grained, calcareous sandstone
