Pteraspids were early agnathan vertebrates. They lived from later Silurian to the end of the Devonian. Fossils are found in Canada, Europe and North America.

The whole group has the head and front of the body armoured. Delicate, finger-like parts of the plates were at the edges of the mouth. This suggests they were filter feeders taking plankton from the water column..
