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