Ponte Serra, PS 9 (Jurassic of Italy)

Where: Italy (46.0° N, 11.8° E: paleocoordinates 33.1° N, 20.9° E)

• coordinate stated in text

• hand sample-level geographic resolution

When: Listato Member (Calcare Selcifero di Fonzaso Formation), Callovian (166.1 - 163.5 Ma)

• sample PS 9, lithozone C, UAZ95: 7-8 [An Early Oxfordian age can not be firmly excluded on the basis of radiolarians. But the Early Oxfordian age is not likely, because calcareous nannofossils of Callovian age are associated throughout the studied interval.]

• bed-level stratigraphic resolution

Environment/lithology: basinal (); lithified, cherty/siliceous wackestone

• thin to medium bedded red cherty limestones consisting of radiolarian wackestones

Size class: microfossils
