The Devonian period lasts for about 60 million years from about 415 to 355 million years ago. It is also known as the “Age of fishes”. The period is a part of the Paleozoic era.

Fishes in the Devonian period mostly belonged to the group Placoderme (or plate-skinned fishes). They possess powerful jaws lined with bladelike plates which acted as teeth. These prehistoric fish lived from the Silurian to the end of the Devonian period. Early placoderms mostly fed on mollusks and other invertebrates.
