Sample B-bulk, Settsass Scharte (Triassic of Italy)

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

• coordinate stated in text

• small collection-level geographic resolution

When: Trachyceras aon ammonoid zone, Cassian Formation, Julian (235.0 - 232.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: basinal (); poorly lithified, brown, gray marl

• The lithology is typical of the basin facies of the Cassian Formation.
• Grey to- brownish poorly lithified claystones to marlstones. Thin beds of marly limestones are also present.

Size classes: macrofossils, mesofossils, microfossils

Preservation: replaced with calcite

Reposited in the BSP

Collection methods: bulk, peroxide, sieve

• The original weight of sample B–bulk was not noted and the mesh size used is

•also unknown, but it was finer than 0.5 mm because foraminiferans are much more abundant in this sample than in sample A–bulk.
