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.
Aurunculeia gens
The nomen Aurunculeius is probably derived from the name of the Aurunci, a race of people from rural Campania, conquered by the Romans in 314 BC, during the Second Samnite War. The Aurunculei may have been of Auruncan origin, or perhaps less probably, descendants of the colonists sent to the towns of the Aurunci beginning in 313.
