Description
These medium sized fishes usually could reach a length of 30 centimetres (12 in). They had a laterally compressed body, quite gibbous in the forepart, with a single dorsal fin, well developed and supported by strong spines. The anal fin was about half the length of the caudal one and was also equipped with spiny rays. Also the pectoral fins were long and well developed. The body was covered with large finely wrinkled scales. The mouth was small and had strong conical teeth. They had no palatal teeth nor protracted jaws.
