''Styracocephalus platyrhynchus'' ('spike head') is an extinct species of tapinocephalian therapsid that lived during the Guadalupian epoch. ''Styracocephalus head ornament meant that it could be recognised from a distance. The most striking feature of ''Styracocephalus'' are the large backward-protruding tabular horns.〔(S. H. Haughton, 1929, "On some new therapsid genera", pg. 55 )〕 The crest stuck upwards and backwards, but there is some variation in its shape, and this suggests that it changed throughout life and that it may be sexually dimorphic. ''Styracocephalus'' was a herbivore that may have been fully terrestrial or partly aquatic like the modern hippopotamus. It may have evolved from the estemmenosuchids. Its remains are known from South Africa but it probably had a wider distribution. It was around in length,〔http://www.palaeocritti.com/styracocephalus〕 with a long, wide skull.〔(S. H. Haughton, 1929, "On some new therapsid genera", pg. 55 )〕 ==See also== * List of synapsids 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「Styracocephalus」の詳細全文を読む スポンサード リンク
