Settsass-Scharte (Triassic of Italy)

Where: Italy (46.5° N, 12.0° E: paleocoordinates 12.4° N, 20.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Julian (235.0 - 232.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; reef rocks

• "...these shell beds are found on top of the Settsass-Scharte where they form several thin (10-15 cm) bands of calcarenite intercalated between argillaceous and calcareous marls containing autochthonous soft-bottom associations" (Fürsich & Wendt 1977)

Size class: macrofossils
