The Saltrio Formation (Also known as the Broccatello Formation) is a geological formation in Italy and Switzerland. It dates back to the Early Sinemurian, and would have represented a pelagic or near-epicontinental environment, judging by the presence of marine fauna such as the nautiloid Cenoceras. The Fossils of the Formation were described on the late 1880s and revised on 1960s, finding first marine biota, such as Crinoids, Bivalves and other fauna related to Epicontinental basin deposits.
