''Stromerius'' is an extinct genus of basilosaurid early whale known from the Late Eocene (Priabonian, ) of Fayum, Egypt (, paleocoordinates ).〔. Retrieved July 2013.〕〔. Retrieved July 2013.〕 ''Stromerius'' is known from several well-preserved vertebrae. Distinguishing features for the genus include: long and forward-pointing metapophyses (bony processes) on the lumbar vertebrae; a relatively short lumbar spine with only twelve vertebrae of which four are interpreted as homologous to sacral vertebrae; one of the two thoracic vertebrae found has a dorsally-pointing neural spine interpreted as anticlinal (i.e. the spines of the other vertebrae are inclined towards this specific vertebra) which is a primitive retention in ''Stromerius'' not present in other basilosaurids. ''Stromerius'' is larger than the contemporary ''Saghacetus'' but smaller than the older ''Dorudon''. made ''S. nidensis'' the type species of the subfamily "Stromeriinae", but only mentioned this proposed subfamily briefly in his abstract. The genus is named for German palaeontologist Ernst Stromer von Reichenbach who made a ground-breaking work in the recovery of whale fossils in Egypt. The species' name comes from Latin ''nidus'', "nest", after the Arabic name of the type locality Garet el Esh, "hill of the nest". They are two specimens: described and illustrated BSPM 1902.XI.504-510, seven vertebrae, and described UM 100140, 19 complete or partial vertebrae. ==Notes== 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「Stromerius」の詳細全文を読む スポンサード リンク
