【摘要】 在准噶尔盆地东北缘上石炭统石钱滩组识别出两种生态类型的四射珊瑚动物群，一种是以小型单体无鳞板类型为主的Cyathoxonia动物群，另一种是以发育鳞板类型为主的Caniniid-Clisiophyllid动物群。认为石钱滩组四射珊瑚动物群生活于中–高纬度地区温带气候条件障壁海岸环境中。其中，Cyathoxonia动物群生活于障壁岛向陆一侧相对闭塞但与外海有连通的潟湖环境中，而Caniniid-Clisiophyllid动物群则生活在障壁岛向海一侧适宜有鳞板类型珊瑚生长的中–高能岛滩环境中。更多还原

【Abstract】 Two ecological types of rugose coral fauna can be recognized in the Shiqiantan Formation(Upper Carboniferous), Northeast margin of the Junggar Basin. One is the Cyathoxonia fauna dominated by small solitary forms without dissepiments. The other is the Caniniid-Clisiophyllid fauna dominated by large forms with dissepiments. It is considered that the rugose coral fauna from the Shiqiantan Formation lived in a barrier coastal environment of an extratropical climate in mid to high latitude. The Cyathoxonia fauna lived in the relatively isolated, low-energy and shallow-water lagoons connected to the open sea; while the Caniniid-Clisiophyllid fauna lived in the mid to high energy reef flat environments, which was suitable for coral growth, on the seaward side of the atoll.更多还原
