What Does Ordovician Mean?

The word Ordovician refers to the second-earliest era of the Paleozoic era in the geological timescale. The Ordovician period is the one that came between the Cambrian period and the Silurian period. In other words, it is the one that followed the Cambrian period and the one that immediately preceded the Silurian period.

The Ordovician period is thought to have covered the span of time between 505 million years ago and 443 million years ago. It also refers to the corresponding system of rocks that were in existence during the Ordovician period. It is named after the Ordovices. The Ordovices is the name of a Celtic tribe which was native to Wales. In older literature, the Ordovician period is also sometimes referred to as the Lower Silurian period.
