New 40Ar/39Ar, stratigraphic and palaeoclimatic data on the Isernia La Pineta Lower Palaeolithic site, Molise, Italy

The Isernia travertines are not associated with hot water springs and indicate that the area was frequented at the end of an Interglacial period. The new ages demonstrate that the human frequentation occurred at the beginning of the Middle Pleistocene.
