A mass extinction event/ice age marked the end of the Ordivician Period. The climate, location of landmasses, and number and diversity of species had changed dramatically since the beginning of the period. When the changes that were occurring during the mass extinction event leveled out, a new period began.

The Silurian went from 443.4 ± 1.5mya to 419.2 ± 3.2mya. It spanned from the conclusion of the Ordovician period to the beginning of the Devonian period. However the exact time frame of the Silurian period is unknown and could be off by millions of years because of the fact that that period was set during a significant extinction event. Therefore, the Silurian period lasted about 42 million years, give or take.
