insert Definition (id: null
text: The Piacenzian is in the international geologic time scale the upper stage or
latest age of the Pliocene. It spans the time between 3.6 ± 0.005 Ma and 2.588 ± 0.005
Ma (million years ago). The Piacenzian is after the Zanclean and is followed by the
Gelasian (part of the Pleistocene).
The Piacenzian is roughly coeval with the European land mammal age MN 16, overlaps
the late Chapadmalalan and early Uquian South American land mammal age and falls inside
the more extensive Blancan North American land mammal age. It also correlates with
the Astian, Redonian, Reuverian and Romanian regional stages of Europe. Some authorities
describe the British Red Crag Formation and Waltonian stage as late Piacenzian, while
others regard them as early Pleistocene.
