Caseodus is an extinct genus of eugeneodontid holocephalian from the Carboniferous of the United States (Illinois, Indiana, Kansas, South Dakota) and the Early Triassic of Canada (British Columbia).[2] It was of medium size, measuring 1–1.5 m (3.3–4.9 ft) in length.[3][4]
Eugeneodontida are an extinct order of Chondrichthyes. They are characterized by the presence of tooth whorls. They include iconic genera, such as Helicoprion ("buzz-saw shark"), Ornithoprion, Edestus or Fadenia. Caseodus is one of the few eugeneodontid genera that survived the end-Permian mass extinction event. It is one of the last surviving genera of this clade.[4]
Caseodus is named after the late paleoichthyologist Gerard Case.[5]
