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.
Classical Latin
The Ciceronian Age was dated 671–711 AUC (83 BC – 43 BC), ending just after the death of M. Tullius Cicero, and the Augustan 711–67 AUC (43 BC – 14 AD), ending with the death of Augustus. The Ciceronian Age is further divided by the consulship of Cicero in 691 AUC or 63 BC into a first and second half. Authors are assigned to these periods by years of principal achievements.
