Where: Lombardy, Italy (45.8° N, 10.5° E: paleocoordinates 8.1° N, 20.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Buchenstein Beds Formation, Ladinian (242.0 - 235.0 Ma)

• Curianii Zone (or possibly younger). Guide event for Anisian-Ladinian boundary is undecided - proposals include the base of the Curionii Zone, base of Avisianum Subzone (Reitzi Zone), and base of Reitzi Zone. These collections use the base of the Reitzi Zone as the A-L boundary.

• bed-level stratigraphic resolution

Environment/lithology: basinal (); bioturbated, concretionary, gray, cherty/siliceous lime mudstone

Size class: macrofossils

Collection methods: surface (in situ),
