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.
Messapians
After the conquest of the Salento by the Roman Republic in 266 BC the distinction between the Iapygian tribes blurred as they were assimilated into ancient Roman society. Strabo makes it clear that in his time, the end of the first century BC, most people used the names "Messapia", "Iapygia", "Calabria" and "Salentina" interchangeably for the Salento. The name "Calabria" for the entire peninsula was made official when the Roman emperor Augustus divided Italy in regions and gave the whole region of Apulia the name "Regio II Apulia et Calabria". Archaeology still follows the original Greek tripartite division of tribes based on the archaeological evidence.
