''Scheenstia'' is an extinct genus of neopterygian ray-finned fish from the Cretaceous period. Fossils have been found in Bavaria, France, and England. ''Scheenstia'' is frequently pictured as the prey of the large dinosaur ''Baryonyx walkeri'' because the scales and teeth of these fish were found in the stomach region of a fossil ''B. walkeri'' specimen. The fish remains were previously referred to the related genus ''Lepidotes'', but all Cretaceous species of that genus have since been re-classified as ''Scheenstia'' following detailed phylogenetic analysis. ==Classification== ''Scheenstia'' is a genus of lepisosteiform that is related to the genus ''Lepidotes''. The latter has been one of the greatest actinopterygian wastebasket taxa, with one 2012 study finding species referrable to a minimum of three different and distantly related genera. ''Scheenstia'' is also related to ''Isanichthys''. A cladogram showing the relations of Neopterygii was published in the review, and a simplified version labelling the previous species of ''Lepidotes'' is shown here.〔 }} |2= }} }} }} }} }} |label2=Lepisoteiformes |2= }} }} }} 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「Scheenstia」の詳細全文を読む スポンサード リンク
