Cladocyclus

Summary

Cladocyclus (derived from the Greek κλάδος/kládos ("branch") and κύκλος/kýklos ("circle")[1]) is an extinct genus of Ichthyodectidae. It was a predatory fish of about 1.20 metres (3.9 ft) in length, found in the Albian Romualdo and Crato Formations of the Araripe Basin in northeastern Brazil.[2] The species Cladocyclus geddesi is known from the Winton Formation of Australia.[3] Cladocyclus pankowskii, discovered in the Cenomanian Kem Kem Bed of Morocco in 2007,[4] is reclassified to genus Aidachar.[5]
