Locality 31, Coopers Creek Fm., near Tyers Quarry, Tyers area, Victoria (Devonian of Australia)

Where: Victoria, Australia (38.2° S, 146.5° E: paleocoordinates 25.8° S, 163.4° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Coopers Creek Limestone Formation, Devonian (416.0 - 360.7 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal, gray conglomerate

• ranges from a typical gray limestone through into conglomeratic rocks or even silty, impure limestones; well-beded towards the base, massive at higher horizons; in general, a coarse calcarenite made up essentially of comminuted bioclastic debris, mainly corals, stromatoporoids, and to a lesser degree, algae; in the boola quarry, the rock approaches more a calcilutite

Collection methods: peel or thin section,
