Where: Queensland, Australia (20.0° S, 146.0° E: paleocoordinates 10.9° S, 152.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Burdekin Formation, Givetian (388.1 - 383.7 Ma)

• "stratigraphically higher unit in the Burdekin"

• member-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal packstone

• Burdekin fm. on the whole contains reef, biostrome, lagoon, interreef, and offshore facies. See lithologic description.
• "...in coralline packstones interpreted to represent shallow-water coralline thickets seaward of a biohermal structure. The fauna has been silicified and was recovered by bulk dissolution in acetic acid."

Preservation: replaced with silica
