''Saurichthys'' ('lizard fish') is an extinct genus of ray-finned fish from the Triassic period. Fossils have been found worldwide. ''Saurichthys'' was an elongated, streamlined, fish about long, and looked similar to the modern pike. Its dorsal and anal fins were placed opposite each other well back on the body, and the tail was symmetrical. These features would have made it a powerful swimmer, and it is presumed to have hunted in a similar way to the pike, attacking from an ambush at high speed. Its jaws were extremely long, making up a third of the total body length, and ended in a sharp, beak-like tip.〔(Saurichthys article, featuring swimming and behaviour on prehistoric-wildlife.com )〕 Fossil evidence, in the form of a bolus of bones in the same strata, indicates that ''Saurichthys'' attacked, or possibly scavenged the corpses of fishing pterosaurs such as ''Preondactylus''. Their closest modern-day relatives include the sturgeons, paddlefish, and the bowfins. == Species == * ''Saurichthys (Costasaurichthys)'' Tintori 2013 * †''Saurichthys (Costasaurichthys) costasquamosus'' Rieppel 1985 * †''Saurichthys (Costasaurichthys) paucitrichus'' Rieppel 1992 * ''Saurichthys (Eosaurichthys)'' Liu and Wei 1988 * †''Saurichthys (Eosaurichthys) chaoi'' Liu and Wei 1988 * †''Saurichthys (Eosaurichthys) madagascariensis'' Piveteau 1945 * ''Saurichthys (Lepidosaurichthys)'' Tintori 2013 * †''Saurichthys (Lepidosaurichthys) dayi'' Raymond 1925 * †''Saurichthys (Lepidosaurichthys) elongatus'' Stensiö 1925 * †''Saurichthys (Lepidosaurichthys) ornatus'' Stensiö 1925 * †''Saurichthys (Lepidosaurichthys) toxolepis'' Mutter et al. 2008 * †''Saurichthys (Lepidosaurichthys) wimani'' Woodward 1912 * †''Saurichthys aculeatus'' Henry 1876 * †''Saurichthys acuminatus'' Agassiz 1844 * †''Saurichthys apicalis'' Agassiz 1834 * †''Saurichthys breviabdominali'' 〔(Discovery of two new species of primitive fishes )〕 * †''Saurichthys calcaratus'' Griffith 1977 * †''Saurichthys costatus'' Münster 1839 * †''Saurichthys curionii'' Bellotti 1857 * †''Saurichthys daubreei'' Firtion 1934 * †''Saurichthys dawaziensis'' Wu et al. 2009 * †''Saurichthys grignae'' Tintori 2013 * †''Saurichthys hamiltoni'' Stensiö 1925 * †''Saurichthys indicus'' de Koninck 1863 * †''Saurichthys krambergeri'' Schlosser 1918 * †''Saurichthys longidens'' Agassiz 1844 * †''Saurichthys macrocephalus'' Deecke 1889 * †''Saurichthys majiashanensis'' Tintori et al. 2014 * †''Saurichthys piveteaui'' Beltan 1968 * †''Saurichthys rieppeli'' 〔(Discovery of two new species of primitive fishes )〕 * †''Saurichthys semicostatus'' Münster 1839 * †''Saurichthys stensioi'' Lehman 1952 * †''Saurichthys striatulus'' Henry 1876 * †''Saurichthys subulatus'' Henry 1876 * †''Saurichthys tenuirostris'' Münster 1839 〔(Fossilworks: Saurichthys Agassiz 1843 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Saurichthys」の詳細全文を読む スポンサード リンク
