δ13CCO3 results indicate that the investigated taxa were grazers-browsers in a pure C3 vegetation. According to the δ18OPO4 results Pliocene was characterized by higher temperatures than Early Pleistocene in Central Italy. In North Italy the δ13C values show a sharp increase between MN16a and MNQ16b biozones that is probably linked to the glaciation at 2.7 Ma. Higher δ13C values in MNQ18 and MNQ19-20 in Central Italy, indicating more open vegetation than in the Pliocene.
