Thrissops
''Thrissops'' is an extinct genus of teleost fish from the Jurassic and Cretaceous periods. Its fossils are known from the Solnhofen limestone.〔(Solnhofen und seine Fossilien: Thrissops )〕 ''Thrissops'' were fast predatory fish about long, that fed on other bony fish.〔Orvar Nybelin, "Versuch einer taxonomischen revision der jurassischen Fischgattung Thrissops Agassiz", ''Nature'' (1964)〕 They had a streamlined body with a deeply cleft tail and only very small pelvic fins. ''Thrissops'' was related to the giant ''Xiphactinus'' and may have been an ancestor of the modern ''Osteoglossiformes'', the most primitive group of living teleosts, which includes the arapaima. ==References==
