Callytharra Springs, cycle 9 (Permian of Australia)

Where: Western Australia, Australia (25.9° S, 115.5° E: paleocoordinates 60.6° S, 99.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified, medium-grained, shelly/skeletal, sandy, calcareous mudstone and lithified, shelly/skeletal wackestone

• Normal marine, well oxygenated conditions within storm wave base. Local storm winnowing and bryozoan meadows.
• 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. High density of subaligned fenestrate bryozoan sheets. Lithology 2: Indurated wackestones. Very low angle trough cross-bedding, skeletal lags. Large bioclasts in random orientations or in small aligned clusters.

Size class: macrofossils
