Favosites-Massive Stromatoporoid Community, Hume Limestone, Yass Syncline (Silurian of Australia)

Where: Australian Capital Territory, Australia (34.8° S, 148.9° E: paleocoordinates 2.3° N, 175.4° E)

• coordinate based on political unit

• basin-level geographic resolution

When: Hume Limestone Member (Silverdale Formation), Gorstian (427.4 - 425.6 Ma)

• member-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal grainstone and shelly/skeletal, silty lime mudstone

• Corals and stromatoporoids frequently in growth position, but many are also fragmented. This facies of Hume Limestone, as well as similar facies in Euralie, Gum's Road, and Bowspring Limestones, belong to reef to high forereef zone, in tidal to high subtidal region. High energy BA 2-3; paucity of algae and sensitivity of cnidarians to desiccation favor BA 3.
• "Association is known from thick-bedded biosparites to somewhat silty biomicrites."

Size class: macrofossils

Collection methods: Community is broad and present in several formations; I have attempted to limit list to Hume limestone elements.
