报道了云南早寒武世乌龙箐组关山动物群中新发现的始海百合类棘皮动物化石．关山动物群始海百合是目前所发现的最早的始海百合类之一,具腕、萼和柄,其萼板形态简单,无缝孔和瘤突,腕长,呈旋卷状,柄较长,柄与萼的长度之比较大．关山动物群始海百合类棘皮动物的发现,不仅对研究棘皮动物的早期演化提供了新的线索和材料,而且对研究早期棘皮动物和始海百合类生态习性变迁也有着重要的意义．
The first echinoderm echinoderm fossils discovered in the Guanshan fauna in the Wulongwan Formation of the Early Cambrian in Yunnan Province were reported. Guanshan fauna sea lily is one of the earliest sea lily species found at present, with a wrist, calyx and stem, its calyx plate shape is simple, seamless holes and tumor, wrist long, was convoluted, handle than Long, the ratio of the length of the handle and calyx. The discovery of echinoderms in the sea lily of the Guanshan fauna not only provides new clues and materials for studying the early evolution of the echinoderms but also plays an important role in the study of the ecological habits of early echinoderms and sea lily.
