PEL93, Pelsa-Vazzoler (Triassic of Italy)

Where: Italy (46.3° N, 12.0° E: paleocoordinates 8.8° N, 21.7° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Punta Santner Member (Sciliar Formation), Longobardian (242.0 - 235.0 Ma)

• A few Protrachyceras archelaus ammonoid specimens have also been found, pointing to the longobardicum ammonoid subzone (P. Mietto, pers. comm. 2017). According to Gianolla et al. (2022) the presence of Protrachyceras longobardicum, P. archelaus, P. pseudoarchelaus, Megaphyllites sp. and the conodont Pseudofurnishius murcianus murcianus in the intra-platform basin (SCI1c), suggests that the succession belongs to the middle part of the upper Ladinian (Mietto & Manfrin 1995; Gianolla et al. 2022).

• bed-level stratigraphic resolution

Environment/lithology: perireef or subreef; lithified, massive limestone

• Intraplatform lagoonal carbonates. Deposited in close proximity to a steep subaqueous relief connecting a shallow subtidal reef environment to a deep-water intra-platform lagoon.

Size class: macrofossils

Preservation: replaced with silica

Collection methods: bulk, chemical, acetic
