Rosso Ammonitico is a formation of the Tuscan Nappe, consisting of red nodular limestones with fossils of ammonites of Sinemurian – Pliensbachian age. The name is homonymous to the ‘Rosso Ammonitico’ or ‘Ammonitico Rosso’ lithofacies, describing a series of similar formations of red nodular limestones of middle Triassic to upper Jurassic age that occur in the Mediterranean area.
