Ptyctodus is an extinct armour-plated fish of the late Devonian.[1] Ptyctodus belongs to the family Ptyctodontidae and is of the class Placodermi. They share a close resemblance to modern day chimaeras (Holocephali). Fossils of this armour-plated fish have been found in locations such as in Russia, the Michigan Basis,[2] and Arizona, United States.[3]
