It can be found in Australia, the Czech Republic, France, Germany, Iran, Kazakhstan, Morocco, Poland, the Russian Federation (Urals), Spain, and the United Kingdom (England). == Distribution == Species belonging to the genus ''Trimerocephalus'' have been found in Europe, Morocco, Iran and Australia.〔〔 * ''T. caecus'' has been found in the Upper Devonian (Lower Famennian) of Poland (Holy Cross Mountains), Germany (Harz Mountains, Rhineland, Thuringia), the Russian Federation (Ural Mountains), North Africa, and France (Armorican Massif). * ''T. lentiginosus'' has been excavated from the Upper Devonian of the Russian Federation (Famennian, South Ural Mountains). * ''T. cryptophthalmoides'' is present in the Upper Devonian (Lower Famennian) of Kazakhstan, and the Russian Federation (South Ural Mountains). * ''T. dianopsoides'' occurs in the Upper Devonian of Poland (Famennian, Holy Cross Mountains). * ''T. interruptus'' is deposited in the Upper Devonian of Poland (Famennian, Holy Cross Mountains). * ''T. lacunosus'' has been identified in the Upper Devonian of Germany (Famennian, Thuringia). * ''T. lelievrei'' was collected in the Upper Devonian of Morocco (Famennian, Tafilalt). * ''T. mastophthalmus'' is known from the Upper Devonian of Germany (Lower Famennian, Rhineland, Harz Mountains, Thuringia), Poland (Holy Cross Mountains), England, southwestern Asia, and Kazakhstan. * ''T. mimbi'' has been found in the Upper Devonian of West-Australia (Famennian, McWhae Ridge, west side South Lawford Range, Virgin Hills Formation). * ''T. nigritus'' is present in the Upper Devonian of France (lower Famennian, Red cephalopod limestones, lower member of "griottes" limestones formation, Lower ''Palmatolepis rhomboidea'' subzone, Old quarry of Concours-le-Haut near Causses-et-Veyran, Montagne Noire). * ''T. polonicus'' occurs in the Upper Devonian of Poland (Famennian, Holy Cross Mountains). * ''T. procurvus'' has been identified in the Upper Devonian (Famennian) of Spain (Cantabrian Mountains) and Germany. * ''T. shotoriensis'' was excavated from the Upper Devonian of Eastern Iran (Famennian, lower ''Palmatolepis marginifera''- to upper ''Palmatolepis trachytera''-zone, Shotori-Range). * ''T. sponsor'' has been identified in the Upper Devonian (Famennian) of the Czech Republic (Moravia) and Spain (Cantabrian Mountains). * ''T. steinachensis'' is known from the Upper Devonian of Germany (Famennian, Thuringia, Harz Mountains). * ''T. tardispinosus'' has been found in the Upper Devonian of Australia (Famennian, ''Palmatolepis rhomboidea''-zone; McWhae Ridge, west side South Lawford Range, Virgin Hills Formation). * ''T. trifolius'' occurs in the Upper Devonian of Poland (Famennian, Holy Cross Mountains). * ''T. vodorezovi'' is present in the Upper Devonian of Kazakhstan (Famennian). 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「Trimerocephalus」の詳細全文を読む スポンサード リンク
