The Prionolepis ( Syn .: Aspidopleurus ) is an extinct genus of fish from the order of the lizard fish relatives (Aulopiformes) that lived in the Upper Cretaceous.
features
Prionolepis were medium-sized fish, about 20 cm long, of a slim shape. The head was long and narrow. The dorsal fin was in front of the middle of the body, in front of the pelvic fins. The caudal fin was forked. Sawn scales arranged in rows are characteristic. Prionolepis means "saw scale".
Systematics
Prionolepis is assigned by both Joseph Nelson and Karl Albert Frickhinger to the monotypical family Prionolepidae established by Goody in 1969 and, together with the also extinct families Dercitidae and Ichthyotringidae, to the suborder Ichthyotringoidei within the Aulopiformes (lizard fish relatives). Other scientists assign all Cretaceous lizardfish relatives to the suborder Enchodontoidei, which, however, is not monophyletic .
