ShensiphyllumGeetYü,1974为丛状复体珊瑚,以发育一列马蹄型鳞板,羽榍扇形排列为主要特征,是志留纪四射珊瑚已知唯一发育马蹄型鳞板的属。该属在我国上扬子区广泛分布于上兰多维列统(Llandovery)特列奇阶(Telychian)中,主要产自川北、陕南的宁强组、云南大关的大路寨组(中、上Telychian阶))、湖北长阳的纱帽组及四川朝天的王家湾组(下特列奇阶)。文中报道和描述川北朝天王家湾组中发现的3个新种Shensiphyllumsimplexsp.nov.,S.proliferumsp.nov.,S.intermediumsp.nov.。王家湾组是已知ShensiphyllumGeetY櫣产出的最低层位。详细讨论该属的骨骼构造特征、生长繁殖方式,探讨该属起源及其演化,根据新资料修订该属的属征,赞同将该属置PhacellophyllidaeWedekind科。
ShensiphyllumGeetYü, 1974 is a plexiform complex coral, with the development of a series of horseshoe-shaped scales, feather fan-shaped arrangement as the main feature is the only record of Silurian coral genus known to develop horseshoe scales. The genus is widely distributed in the Llandovery Telychian region in the Upper Yangtze region of China, and is mainly produced in the Ningqiang Formation in northern Sichuan and southern Shaanxi, and in the Daluzhai Formation in Yunnan’s Daguanyuan Telychian Stages), yarn hats in Changyang, Hubei Province, and the Wangjiawan Formation (Lower Trequette Stages) in Sichuan. Three new species, Shensiphyllumsimplexsp.nov., S.proliferumsp.nov., S.intermediumsp.nov, were found in this paper. The Wangjiawan Formation is the lowest level produced by the known Shensiphyllum Geety 櫣. Discussed in detail the structure characteristics of the skeleton, growth and reproduction, explore the genesis and evolution of the genus, according to the new data to amend the genus of the genus, in favor of the genus PhacellophyllidaeWedekind Branch.
