Promontory of Torre del Porticciolo (Permian to of Italy)

Where: Sassero, Italy (40.6° N, 8.2° E: paleocoordinates 3.9° N, 21.8° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Cala del Vino Formation, Kungurian to Kungurian (279.3 - 268.8 Ma)

• Uppermost levels of the Permian Cala del Vino Formation (unit 6), late early Permian to early middle Permian in age, about 30 m below the lower boundary of the Conglomerato del Porticciolo, a lithostratigraphic unit that, locally, marks the beginning of the Triassic sequence.

• bed-level stratigraphic resolution

Environment/lithology: wet floodplain; poorly lithified, bioturbated, red mudstone

• Such lithologies and fluvial architecture are typical of a meandering-channel alluvial system (Fontana et al. 2001; Ghinassi et al. 2009). These deposits were laid down by medium-scale, bed-load streams, under a relatively mild semi-arid climate. The vertebrate remains were found in an alluvial plain mudstone-siltstone layer
• Dark gray, poorly cemented, mudstone-siltstone. The former alluvial plain fine sediments appear homogeneous and deeply bioturbated.

Size class: macrofossils
