Saivodus
Saivodus is an extinct genus of ctenacanthiform fish that existed from early Mississippian in the Carboniferous period.[1] Fossils have been found in Ireland, Scotland, England, Belgium, Morocco, and United States. Teeth assigned to that genus are also known from the Permian (Leonardian) Kaibab Formation.[2]

Taxonomy
Saivodus was erected in 2006. The single species belonging to this genus was formerly included in the unrelated genus Cladodus.[1]
Description
Based on tooth measurements, Saivodus would have been the largest member of its group currently known, reaching lengths of up to 9 m (30 ft), although one study estimated its length around 6–7 m (20–23 ft).[3] The shape of the teeth suggest it targeted soft-bodied prey.[4]
