Caffaro riverbed section, Bagolino, 61 m (Triassic of Italy)

Where: Lombardy, Italy (45.8° N, 10.5° E: paleocoordinates 6.2° N, 22.4° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Secedensis ammonoid zone, Buchenstein Formation, Illyrian (247.2 - 242.0 Ma)

• Secedensis Zone. "Knollenkalke."

• bed-level stratigraphic resolution

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

• Grey-weathering nodular limestone beds have characteristic undulating and knobby surfaces spaced from cm to dm apart, and consist mainly of filament- and radiolarian-microsparites (mudstone-wackestone), often strongly bioturbated. Silicification may be diffuse or nodular. Often mixed with fine ash- and crystal-tuffs.

Size class: macrofossils

Collection methods: surface (in situ),
