Canonia is an extinct genus of jawless fish found in Canada. There are two species in this genus, C. grossi and C. costulata.[1] The C.grossi species is thought to be from the Devonian Period (Early Lochkovian).[2] Fossils of C.grossi have been found in the Boothia Peninsula.[3] Isolated scales of Canonia are streamlined to minimize drag, similar to modern sharks capable of strong swimming in open waters.[4][5]
