See text Caturus (from Greek: κατω kato, 'down' and Greek: οὐρά ourá 'tail')[1][2] is an extinct genus of predatory marine fishes in the family Caturidae in the order Amiiformes, related to modern bowfin.

These inconsistencies make both Caturus and Pachycormus (which was initially described with Uraeus gracilis as one of its species) taxonomically unstable genera, necessitating a petition to the Bulletin of Zoological Nomenclature to retain C. furcatus as the type species of Caturus.

Other species such as C. giganteus (Wagner, 1851) have been reclassified into other genera within the family Caturidae, such as Strobilodus.

The species C. brevis Winkler, 1862, C. latidens Woodward, 1918, and C. velifer Thiollière, 1851, are no longer classified in Caturus or even Caturidae, and are yet to be reclassified.

Another potential record from Argentina is now placed as an indeterminate caturoid, possibly in the genus Catutoichthys.
