Lily Creek Section K200 (Cambrian of Australia)

Where: Queensland, Australia (22.0° S, 140.3° E: paleocoordinates 24.9° N, 174.8° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Peichiashania secunda - Prochuangia glabella trilobite zone, Chatsworth Formation, Iverian (498.5 - 494.0 Ma)

• Should be Jiangshanian

• bed-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified, pyritic, ooidal, peloidal, sandy grainstone

• "rocks were deposited in high energy shallow subtidal, intertidal and possibly aeolian environments"
• "A one-metre unit comprising sandy skeletal pelletal packstone overlying a lithified surface of interlaminated sandy pelletal grainstone and pelletal wackestone. The thin section contains moderately compacted ooids, local dolomite veins and patches, and dusty pyrite or limonite laminae."
