| Abstract: | The gastrozooid with tentacle herein were collected from the early Cambrian Kuanchuanpu Formation at the Shizhonggou section,Ningqiang County,Shaanxi Province,China.The problematic phosphatic tubular microfossils with bud are collected from the same outcrop layer.The authors tentatively suggest that these tubular microfossils with buds and the gastrozooid may have related to the polyp Obelia. |
