Mostyn Vale Fmn corals and conodonts, Keepit, NSW (Devonian of Australia)

Where: New South Wales, Australia (30.9° S, 150.5° E: paleocoordinates 22.3° S, 154.8° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Mostyn Vale Formation, Late/Upper Frasnian (379.5 - 376.1 Ma)

• Conodonts indicate Ancyrognathus triangularis, lower Pa. gigas; probably upper Pa. gigas; and uppermost Pa. gigas (Pa. linguiformis) zones. Corals from allochthonous blocks. Late to latest Frasnian age.

• formation-level stratigraphic resolution

Environment/lithology: marine; gypsiferous limestone

• Interpretation of limestone blocks is as shallow water deposits that are allochthonous, having been transported from the west into a fore-arc basin. Bedding in limestones discordant with that of enclosing strata. Indicators of shallow-water origin include birdseye textures, rare gypsum, Stromatacthis, calcite spar in voids, encrusting stromatoporoids, and algae.
• [Allochthonous Lst blocks in pebbly sandstone to conglomerate and pebbly mudstone, volcanic breccia, volcanis flows and agglomerates, and interbedded mudstone, siltstone,tuff, greywacke and breccia.
