Ducanfurgga 4 (Triassic of Switzerland)

Where: Switzerland (46.7° N, 9.8° E: paleocoordinates 9.1° N, 21.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Prosanto Formation, Fassanian (242.0 - 235.0 Ma)

• Bed 22: upper part of the Prosanto Formation

• group of beds-level stratigraphic resolution

Environment/lithology: basinal (); lithified lime mudstone

• The depositional environment of the Prosanto Formation is interpreted as a localized basin with a stratified waterbody that resulted in oxygen-depleted bottom water.

• The fossiliferous layers are thinly bedded and laminated.

Size class: macrofossils

Preservation: adpression

Collected by H. Furrer in 1989

Collection methods: mechanical

• Starting in 1989, a large number of new Prosanto Formation fossils have been discovered in systematic excavations by Heinz Furrer and his team (Zürich University). Repository: PIMUZ.
