Val Parina, S939 (Triassic of Italy)

Where: Bergamo, Italy (45.9° N, 9.7° E: paleocoordinates 8.5° N, 20.6° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Eoprotrachyceras gredleri ammonoid zone, Esino Formation, Fassanian (242.0 - 235.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: perireef or subreef; lithified limestone

• Massive bioclastic limestones and patch reefs and represents the margin of Esino platform facing an intraplatform trough or an open basin to the south.
• Collected from bioclastic lenses 10-100cm thick, at the transition between lithozones 3 and 4 which partially interfinger in the lower-middle part of the Esimo Limestone, from 200-350m above the base to 500m below the of the formation. Lithozone 3 consists of bindstones, bafflestones and bio-intraclastic packstones and wackestones, whereas lithozone 4 consists of peloidal and bio-intraclastic packstones, wackestones, mudstones, and rarely grainstones.
