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.
Gallura
The historic period that goes from 1700 BC to the Roman Age is also known in Sardinia as the Nuragic Age. The particular name of this historic period takes after the Nuraghes, the biggest megalithic edifices ever found in Europe, which still today represent a symbol for Sardinia.
The Phoenicians founded the (hence Punic) city of Olbia (renamed in Greek, though), which was conquered by the Romans with all of Gallura in 238 BC.
