Where: South Australia, Australia (34.8° S, 137.7° E: paleocoordinates 13.4° N, 161.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kaimenella reticulata small shelly zone, Ramsay Formation, Toyonian (512.9 - 510.2 Ma)

• bed-level stratigraphic resolution
