- The Lower Ordovician epoch (-485.4 Ma to –470.0 Ma) is the lower part of the Ordovician epoch. The Ordovician is named after the Welsh tribe of the Ordovices.

Carbon dioxide levels were very high at the Ordovician period's beginning. By the late Early Ordovician, the Earth cooled. (Adapted from: https://en.wikipedia.org/wiki/Ordovician)
