Where: Western Australia, Australia (25.9° S, 115.5° E)

• Paleocoordinates: 62.0° S, 98.5° E (Wright 2013)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Callytharra Formation, Sakmarian (293.5 - 290.1 Ma)

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, medium-grained, shelly/skeletal, gray, sandy, calcareous mudstone and lithified, medium-grained, quartzose sandstone

• Normal marine, well oxygenated conditions within storm wave base.
• 0.8 to 7 m thick bioclastic sandy mudstones (sand mainly composed of fenestrate

•bryozoa and brachiopod debris with a broad peak in the medium to coarse size

•fractions). Terrigenous mud matrix. Decreasing siliciclastic sand (mainly very fine) content upsection. Medium quartz-feldspar sandstone with very low angle cross-bedding, skeletal lags.

•Large bioclasts

•in random orientations

•or in small aligned clusters.
