| 摘 要： | 贵州寒武系含有丰富的棘皮动物化石,其中凯里组及杷榔组中的始海百合数以千计.近期贵州下司淑里村杷榔组上部粉砂质泥岩中发现的新类型殷氏原始球状始海百合（新属、新种）Protogloboeocrinus yini （gen.et sp.nov.）,使贵州寒武系棘皮动物分异度加大,达8属、种及1科、属、种未定,分属3个亚门.演化趋势是：类群增多,始海百合个体变小,缝孔变圆,吸盘附着的化石类型增多,生态日趋复杂.凯里生物群也是棘皮动物大辐射的窗口.

| Abstract: | Guizhou Cambrian contains abundant fossils of Echinoderms, among which there are thousands of Eocrinoides in Kaili Formation and Balang Formation. Recently, the Protogloboeocrinus yini （gen. et sp. nov. ） were found in the silty-mudstone from the upper part of Balang formation at Shuli Village, Xiasi Town, Majiang County, Guizhou Province and enlarges the disparity of Echinoderms in Cambrian from Guizhou. There are 8 species and 1 indeterminate species, belonging to 3 Subphyllums respectively. The evolution trend is： the taxa increase, the individual of Eocrinoides becomes smaller, the sutural pole gets rounder, and the types of fossils attached with holdfast also increase. Kaili Biota also is a window of great radiation of Echinodermas. |
