| 摘 要： | 下寒武统澄江生物群、中寒武统布尔吉斯页岩生物群及下寒武统牛蹄塘生物群均产有Crumillospongiabi-porosa,由于产C.biporosa的牛蹄塘生物群下部层位低于澄江生物群,贵州遵义松林可能是C.biporosa的最低层位及发源地。本文描述了贵州遵义下寒武统牛蹄塘生物群的C.biporosa,为C.biporosa的发生、演化及古地理分布提供了重要的信息和证据。

| Abstract: | Crumillospongia biporosa from the lower part of Niutitang Biota (Lower Cambrian) is described in the present paper. Crumillospongia biporosa are found in Lower Cambrian Chengjiang Biota and Middle Cambrian Burgess Shale Biota, too. The horizon of lower part of the Niutitang Biota is earlier than that of Chengjiang Biota. It seems that Songlin Town, Zunyi County, Guizhou Province is the cradle of C. biporosa, and offers important information and evidence for origination, evolution and distribution of C. biporosa. |
