They are distinguished by horn-like structures, probably for display or agonistic behavior. Apart from the best known genus, ''Estemmenosuchus'', the group is poorly known. To date, their fossils are known only from the Perm region of Russia (a region referred to by Russian paleontologists as the Cis-Urals). ==Description== Estemmenosuchids are among the most distinctive of the Permian tetrapods. The high and massive skull is equipped with a number of horns projecting both upwards and outwards, which were probably used for intra-specific display. The incisors and canine teeth are large, but those at the side are reduced, with a serrated apex, and may have helped to break up plant material, although they were too small to be of much use. The body is large and bulky, indicating a large digestive tract for digesting volumes of plant food. The skull superficially resembles that of ''Styracocephalus'', but the "horns" are formed from different bones. 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「Estemmenosuchidae」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.
