''Condylopyge'' is a genus of very small trilobites, that lived during the latest Early and the early Middle Cambrian, in what are today Canada (Newfoundland and New Brunswick), Czech Republic, England and Wales, France, Germany, Italy, Morocco, the Russian Federation (North-East Siberia), Spain, Turkey and Sweden. It can easily be distinguished from all other Agnostida because the frontal lobe of the central raised area of the headshield (or glabella) is wider than the rear lobe. It looks like ''Pleuroctenium'' but the frontal glabellar lobe does not fold around the rear lobe, as it does in ''Pleuroctenium''. == Distribution == * ''C. antiqua'' was excavated from the latest Lower to the early Middle Cambrian of Italy (Campo Pisano Formation, 4 km south-east of Fluminimaggiore, Iglesiente area, South-West Sardinia). * ''C. imperator'' were found in the early Middle Cambrian of France (''Paradoxides'' beds, Herault, Languedoc). * ''C. carinata'' is present in the early Middle Cambrian of Morocco (''A. birameus'' beds, Tissafin stage, Jbel Wawrmast Formation, Feijas internes group, Touchagt near Tinedjad, in the North of Alnif). * ''P. cruzensis'' has been identified from the early Middle Cambrian of Spain (''Acadoparadoxides mureroensis'' trilobite zone, Valdemiedes Formation, Aragon). * ''C. matutina'' is present in the Middle Cambrian of Turkey (Çal Tepe Formation, near Seydişehir, Central Taurides). * ''C. rex'' has been collected from the early Middle Cambrian of the Czech Republic (''E. pusillus''-zone, Týřovice an Skryje, Bohemia),〔 and Spain (''Badulesia''-zone, Los Villares Formation, Sierra de Córdoba). * a ''C. sp.'' occurs in the early Middle Cambrian of the United States (Chamberlain's Brook Formation, Braintree Member, Hayward's Quarry, Massachusetts). * a ''C. sp.'' also occurs in the early Middle Cambrian of Spain (''Solenopleuropsis thorali'' trilobite zone, Genestosa Member, Oville Formation, Los Barrios de Luna, León). 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「Condylopyge」の詳細全文を読む スポンサード リンク
