Tselfatia is an extinct genus of Cretaceous bony fish. Originally described from (and named after) Djebl Tselfat in Morocco, it has since been discovered at sites in several other countries (Texas/USA, Germany, Mexico, Italy and the former Yugoslavia). The type species, Tselfatia formosa, was named and described in 1943 by French paleontologist Camille Arambourg.[1][2] A second species, T. dalmatica, was named in 1980 from the Dalmatian Coast of Croatia.[3]
