摘　　要：通过对采自贵州关岭地区三叠系小凹组的2块海百合化石标本的研究,认为该标本与以前发现于该地区相同层位的Traumatocrinus hsui Mu在冠部和茎部结构特征均有较大差异,并据此建立新种Traumatocrinus strumiformis sp.nov.。Two Crinoid specimens were found recently in Triassic Xiaowa Formation in Guanling area of Guizhou Province.The crown and stem structures of these two specimens are different from Traumatocrinus hsui Mu,which was found in the same level of the same area.Consequently,a new species Traumatocrinus strumiformis sp.nov.was established.
