A species of ichthyodectiform fish, Cladocyclus pankowskii sp.nov. is described based on a single well-preserved braincase specimen from the Cenomanian Kem Kem beds of southern Morocco. It differs from the type species, C. gardneri, in the proportions of the skull roof. The presence of a species of Cladocyclus in Morocco adds yet another vicariant taxon shared between Brazil and Africa in the mid-Cretaceous, when Africa was separating from South America during the formation of the South Atlantic.
