摘　　要：从贵州独山早石炭世上司组海参化石的发现,进一步讨论海参集合体的特点及其意义,海参化石组合特征,并与国内外石炭系海参进行对比,同时描述了上司组海参化石8属12种,包括5新种.Abundant Holothurian sclerites described in this paper were collected from the Shangsi Formation of the Tatang Stage. (upper part of the lower Carboniferous) in Dushan, Guizhou, with 8 genera and 13 species (Table I), including 5 new species, namely, Theelia sinensis; Thuroholia dushanensis; Thuroholia symmetrica; Eocaudina guizhouensis and Paraeocaudina circularis. Among them, Microantyx botoni was reported from the Rockford Limestone (Lower Mississippian) in Indiana, the Kinderhookian (Lower Mississippian) in Montana and Missouri of America, the Shaodon Formation (lower part of the Aikuan Stage), the Mengkungao Formation (middle part of the Aikuan Stage), the Shihtengtze Formation (lower part of the Tatang stage) in Huan and the Tai- yuan Formation (Upper Carboniferous) in Henan of China; Achistrum ludwigi from the Rockford Limestone in Indiana, the Kendrick Shale (lower Pennsylvanian) in Kentucky of America and the Shaodong Formation in Hunan of China. Thuroholia marginata and T. mccormacki from the Lowet Carboniferous of Amerlca, the Shaodong Formation in Hunan and the Taiyuan Formation in Henan of China; Thuroholia regularis from the Aikuan Stage(lower part of Lower Carboniferous) in Hunan; Eocaudina mccormacki from the Kind rhookian of Montana and Missouri of America and the Taiyuan Formation in Henan of China, while individual Theelia sinensis was collected for the first time from the Shangsi Formation of Duhan, Guizhou, and Theelia from the Kendrick Shale in Kentucky of America. According to the faunal characteristics, the Shangsi Formation might belong to the Visean Stage of Early Carboniferous.

I, fig. 26) Sclerites in the form of a perforate plate, with cross seaion flat, commonly subcircular in outline. Holothurian discs with a single central perforation, an intermediate ring of 6 perforations, an outer ring of approximately 14-15 perforations and surrounded by a bo
