Lombardian Alps, Riva di Solto Formation (Triassic of Italy)

Where: Italy (46.0° N, 10.0° E: paleocoordinates 30.7° N, 14.2° E)

• coordinate estimated from map

• basin-level geographic resolution

When: Riva di Solto Formation, Rhaetian (208.5 - 201.3 Ma)

• The Riva di Solto Formation is assigned to be lower Rhaetian, some workers believe that at least the lower parts of the formation may be uppermost Norian in age.

• formation-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified shale and lithified limestone

• shales and thin-bedded limestone

Size class: macrofossils
