D9, Cassian bulk collection (Triassic of Italy)

Also known as Reef 162

Where: Italy (46.6° N, 12.2° E: paleocoordinates 12.4° N, 20.3° E)

• coordinate based on unpublished field data

• 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
