Landwassergebeit (Triassic of Switzerland)

Where: Switzerland (46.8° N, 9.8° E: paleocoordinates 9.2° N, 21.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• 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

Collection methods: Repository: Paläontologisches Institut und Museum - Universität Zürich (PIMUZ)
