Adrianitinae is a subfamily of the Adrianitidae which is part of the goniatitid superfamily Adrianitaceae. The Adrianitinae which comprise the more advanced genera in the Adrianitidae have sutures that form 14 to 30 lobes. Shells may be discoidal or globular or in between. ==Taxonomy== The Adriantinae which are found widespread in lower and middle Permian marine sediments are derived from ''Crimites'', a genus in the more primitive Emilitinae subfamily, through ''Neocrimites'' which gave rise to ''Adrianites'', ''Epadrianites'', ''Pseudagathiceras'', and ''Sosiocrimites'' (Saunders et al. 1999). In the older taxonomy of Miller et al.,(1960), the Adrianitinae consists of ''Adrianites'', ''Hoffmannia'', ''Doryceras'', ''Crimites'', and ''Texoceras''. ''Hoffmannia'' and ''Texoceras'' are each now their own subfamily, Hoffmanniinae and Texoceratinae respectively. ''Doryceras'' and ''Crimites'' are removed from the Adrianitinae and placed in the Emilitinae (sometimes given as Emiliidae). ''Epadrianites'', ''Metaricoceras'', ''Neocrimites'' and ''Sosiocrimites'', which were considered possible equivalents of ''Adrianites'' in Miller et al., are distinguished separately in what is now the Adrianitinae. ''Pseudagathiceras'', once thought a possible equivalent of ''Doryceras'', has been added. ''Neocrimites'' is the most primitive of the Adrianitinae and is the source (Saunders et al. 1999) for ''Adrianites'', ''Epadrianites'', ''Pseudagathiceras'', and ''Sosiocrimites''. ''Adrianites'' and related genera are found widespread in the middle Permian, especially from Sicily and Texas. 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「Adrianitinae」の詳細全文を読む スポンサード リンク
