近年来,我队在研究泥盆—石炭纪碳酸盐岩地层时,不断发现一些保存完好的海参化石,笔者曾作过报道。1982年底,在湖南临武县香花岭下石炭统岩关阶又发现了丰富的海参化石。据此,对湖南下石炭统岩关阶的时代、划分和对比提出一些粗浅的认识。 临武县香花岭剖面位于香花岭矿场东侧约3公里处的下芳冲。

Abundant Holothurioidea fossils were collected in 1982 from the Shaodong Formation (the lower part of the lower Carboniferous ) in Linwu county of Hunan,They contain 6 genera and 11 species,namely Gutschick, Zhang, 2hang, Zhang, Zhang, (Frizzel & Exline) . Langenheim & Epis,. Zhang,.,.(Frizzel & Exline), Zhang. was discovered in the Rockford limestone (lower Mississippian) of Indiana of USA and the Shidengzi Formation (the upper Lower Carboniferous) in Longhui county of Hunan. was discovered in the Rockford limestone and the Escabrosa limestone (also Lower Mississippian) of Arizona. was found in the lower part of the lower Carboniferous from Shaoyang and Wugang of Hunan. and were discovered in the lower Carboniferous of Wugang. Mortensenites teat, and were first collected in lower Carboniferous of Linwu county of Hunan.According to this faunae collected,the Shaodong Formation may belong to the Tournaician stage of Early Carboniferous.
