Aztecodus is an extinct genus of Chondrichthyian from the Devonian period.[1] It is named for middle to late Devonian-aged Aztec Siltstone of southern Victoria Land, Antarctica which produces this genus. It currently contains a singular species, A. harmsenae. It is named for sedimentologist Dr. Fraka Harmsen. It has unique teeth which are broad with widely divergent cusps separated by a crenulated cutting edge.[2] Anareodus statei may be a junior synonym to this genus and species.[3]
