| 摘 要： | 贵州寒武系刺细胞动物丰富，有4属7种及1未定种，包括帐篷螺Scenella Billings，1872、寒武线螺CambbrovitusMao，Zhao，Yu＆Qian，1992、拜如尼亚虫Byronia Mathew，1899、楔叶形虫Sphenothallus Hall，1847共4属化石，主要层位由老到新为遵义松林中南村牛蹄塘组，剑河八郎清虚洞组、凯里组，为中国寒武系最主要的产出地区。Sphenothallus及Byronia的研究尤为详尽，其中Sphenothallus为一个两侧具管状加厚物，具吸盘的长细锥管状刺细胞动物，具有有性及无性生殖等特征。贵州寒武系刺细胞动物的研究将促进我国及全球寒武系刺细胞动物的研究。

| Abstract: | There are abundant species of Cnidaria from the Cambrian in Guizhou, so far we have found 4 genera, which are Scenella Billings, 1872, Cambbrovitus Mao, Zhao, Yu ＆ Qian, 1992, Byronia Mathew, 1899, Sphe- nothallus Hall, 1847, including 7species and 1 uncertain. Output in the horizon are the Niutitang Formation in Zhongnan village, Songlin town, Zunyi County , the Tsinghsutung Formation and the Kaili Formation in Balang village, Jianhe County from bottom to top. Sphenothallus and Byronia are studied particularly detailedly, with Sphenothallus having longitudinal thickenings and a holdfast. The tube of Sphenothallus, tapering gradually from the apeure to the attachment, exhibiting both sexual reproduction and asexual reproduction. The study of Cnidaria from the Cambrian in Guizhou will promote the worldwide research of Cnidaria. |
