Cladodus is an extinct genus of cartilaginous fishes in the family Ctenacanthidae. As the name implies, they are a type of cladodont, primitive sharks with teeth designed to snag fish and swallow them whole, instead of sawing off chunks to swallow.
Fossils of Cladodus have been found in Barkip, Scotland,[1] Bundock and Laurel Formations, Australia[2] and in the Pitkin Formation (Carboniferous period) in Arkansas, United States. In addition, fossils attributable to Cladodus are known from the Manning Canyon Shale of Carboniferous age in the state of Utah.[3]
