Pr1, Cassian bulk collection (Triassic of Italy)

Also known as Reef 162

Where: Italy (46.5° N, 11.9° E: paleocoordinates 12.4° N, 20.1° 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• coordinate based on unpublished field data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

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

• Patch reefs on extensive carbonate platform
• Small patch reefs, laterally grading in to oolitic limestones. Material supposedly stems from reefs, although it was mostly collected from marly interbeds.

Size class: macrofossils

Preservation: original aragonite, original calcite

Collection methods: bulk,
