Dickosteus is an extinct genus of coccosteid arthrodire placoderm from the Late Eifelian to Early Givetian stages of the Middle Devonian period. Fossils are found in Orkney and Caithness, Scotland. It was a small placoderm with a total body length of 43.7 cm (17.2 in).[1] It is one of the few placoderms for which complete bodies are known.
