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]
