The Silurian Period of time is usually broken into early ([[Llandovery epoch|Llandovery]] and [[Wenlock epoch|Wenlock]]) and late ([[Ludlow epoch|Ludlow]] and [[Pridoli]]) subdivisions ([[epoch (geology)|epoch]]s). Nevertheless, some schemes use an early (Llandovery), middle (Wenlock) and late (Ludlow and Pridoli) breakdown. These [[faunal stage]]s are characterized by their [[index fossil]]s, new species of colonial marine [[Graptolite]]s that appeared in each. ''Epochs'' of time correspond to ''series'' of rocks (as ''periods'' of time correspond to ''systems'' of rocks), which are referred to as belonging to the lower, middle, or upper part of the rock column, analogous to early, middle, or late Silurian time. The epochs and stages from youngest to oldest are:
* '''Pridoli''' Epoch - no stages defined (late Silurian)
