Kemp (2005) ''The origin and evolution of mammals'' p.24.〕 ''Ianthasaurus'' lacks many of the spectacular specializations seen in ''Edaphosaurus''. For example, the marginal dentition of ''Ianthasaurus'' is similar to that of insectivorous reptiles, with slender conical teeth which are slightly recurved at the tips, and there is a slight development of a caniniform region. The palatal and mandibular dentition is unspecialized, and there are no batteries of teeth for crushing of plant materials. Also unlike ''Edaphosaurus'', ''Ianthasaurus'' was lightly built and was probably quite agile. The skull was similar to that to ''Haptodus'', a sphenacodontid, though they were distantly related. 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「Ianthasaurus」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
