Adrianitidae is a family in the Adrianitaceae, a superfamily of ammonites in the cephalopod order, Goniatitida, known from the Middle Pennsylvanian to the Middle Permian. Members of the Adrianitidae, named by Schindewolf in 1931, and of the Adrianitaceae, have shells (conchs) that are discoidal to globular with umbilici that vary in form, and sutures with 10 to 30, more or less equal, lobes. The Adrianitinae which come from the Lower and Middle Permian have sutures that form 14 to 30 lobes. Genera included ''Adrianites'', ''Hoffmannia'', ''Doryceras'', ''Crimites'', and ''Texoceras''. The Dumbaritinae which come from the Middle and Upper Pennsylvanian (U Carb) have sutures with only 10 lobes. ''Clinolobus'', from the Middle Permian of Sicily, has about 14 lobes with the course of the external suture forming a V. ==Classification== The Adriantidae contains three subfamilies, the Adrianitinae, Hoffmanniinae, and Texoceratinae. Most of the genera in the family, some 15 in number, are included in the Adrianitinae. The remaining two are included, one each, in the Hoffmanniinae and Texoceratinae. ''Dunbarites'' and ''Clinolobus'' included in the Adrianantidae in the older edition of Treatise (Part L) have since then been reassigned; ''Dunbarites'' to the Schistocerataceae and ''Clinolobus'' to the Neoicocerataceae The Emilitinae, established to include the most primitive members of the family, based on ''Emilites'', have been reincorporated into the Adrianitinae. ''Pamiritella'' for which the Pamiritellinae was established is considered also part of the Adrianitinae. 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「Adrianitidae」の詳細全文を読む スポンサード リンク
