Araripichthys is an extinct genus of bony fish from the Cretaceous Period. Fossils of the genus have been found in Morocco, Mexico, Venezuela, and Brazil.
features
Araripichthys had a high-backed, laterally flattened body with a long dorsal and anal fin. The anal fin was partially scaled. The pectoral fins were very low on the body, pelvic fins and a pelvic fin skeleton are missing. The caudal fin was forked. The head was broad, the eyes large. The moderately deep mouth was toothless, the premaxillary was extensively protractile and formed the edge of the upper jaw. It is controversial whether the fins of the genus had hard rays .
Systematics
The systematic position of Araripichthys is more uncertain. Among other things, a basal position within the Teleostei , a relationship with the mucous head-like (Beryciformes), the barbed fish (Acanthopterygii) and the shiny fish-like (Lampriformes) was assumed.
