Berycopsis
''Berycopsis'' is an extinct genus of beardfish from the Cretaceous period. It was about long and one of the first members of the Acanthopterygii, the group that includes the present day barracuda, swordfish, seahorses, and flatfish. Like its modern relatives, the first fin rays in the dorsal and anal fins were modified into defensive spines, and the pelvic fins were located close to the pectoral fins. ''Berycopsis'' was one of the earliest fish known to have these features, which are widespread today. ==References==
