Also known as Reef 162

Where: Italy (46.7° N, 12.2° E: paleocoordinates 12.5° N, 20.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Cassian Formation, Julian (235.0 - 232.0 Ma)

• Age range indicated as Langobardian ton ?Julian, now confirmed to be early Carnian (Cordevolian)

• bed-level stratigraphic resolution

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