Early Devonian - Citizendia

In the geological timescale, the Early Devonian epoch (from 416. The geologic time scale is a chronologic schema (or idealized Model) relating Stratigraphy to time that is used by Geologists and other 0 ± 2. 8 million years ago to 397. 5 ± 2. 7 million years ago) occurred during the Devonian period, after the end of the Silurian period. The Devonian is a geologic period and system of the Paleozoic era spanning from to million years ago. The Silurian is a geologic period and system that extends from the end of the Ordovician period about 443

The Early Devonian epoch is subdivided into three stages: Lochkovian, Pragian and Emsian.

Devonian period
Lower/Early Devonian	Middle Devonian	Upper/Late Devonian

The Devonian is a geologic period and system of the Paleozoic era spanning from to million years ago.
