What it is Filled
A long and distinct period of time, either one marked by a distinctive character or one reckoned from a fixed point or event; in everyday use an era is a stretch of history seen as a unit, such as an age, an epoch or a golden age, while in geology and dating systems it has more precise meanings. The registry aliases name related terms including epoch, antiquity, age, historic period and modern era.
