Olang, northern Dolomites, Italy (Triassic of Italy)

Also known as Reef 36

Where: Italy (46.8° N, 12.0° E: paleocoordinates 6.3° N, 23.8° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Recoaro - Upper Serla Formation, Pelsonian (247.2 - 242.0 Ma)

• Stratigraphic resolution very fine, but lumped from several horizons in the collection.

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified reef rocks

• Reef mounds on lower to middle ramp position. Data from several facies: oncoid-peloid wacke-floatstone, bioclastic wackestone, lump packstone, bioclastic grainstone, algal bindstone, breccia, grapestone, silty wackestone.

Size classes: macrofossils, mesofossils, microfossils

Collection methods: quarrying, peel or thin section,

• Data only occasionally separated fro different outcrops and formations. Thus compiled for whole region and two reefal formations
