Halysitid Community, Canberra Formation, Canberra locality CC57 (Silurian of Australia)

Where: Australian Capital Territory, Australia (35.3° S, 149.1° E: paleocoordinates 4.3° N, 175.4° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Canberra Formation, Wenlock (433.4 - 427.4 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; silty grainstone and calcareous mudstone

• Acid volcanogenic material common in the formation, which is overlain by dacitic to rhyolitic vaolcanics. The community thus appears associated with tectonically unstable areas, with likely strong current activity...moderately energetic environment, probably nearly wave base, thait is BA 3"

• Community in general described as coming from "shales interbedded with thin silty limestones," thin-bedded generally silty calcarenites," and "thin interbedded siltstones and mudstones, which may be calcareous"

Size class: macrofossils

Collection methods: Table 14.2 (includes specimen counts).
