Campanian
The Campanian is, in the ICS' geologic timescale, the fifth of six ages of the Late Cretaceous epoch (or, in chronostratigraphy: the fifth of six stages in the Upper Cretaceous series). The Campanian spans the time from 83.6 ± 0.7 Ma to 72.1 ± 0.6 Ma (million years ago). It is preceded by the Santonian and it is followed by the Maastrichtian.
San Valentino Torio
The first traces of human presence in the southern Campanian plain date from the 9th–6th centuries BC, including a necropolis with 1400 sepultures, attributed to the Sarrastri tribe. The territory was invaded by the Samnites in 421 BC.
