摘要
在前人划分的下二叠统中发现Sycidium化石。笔者讨论了该化石层位的时代归属,认为含Sycidium haikouense—S.lagenarium组合的野猪塘组属东岗岭期的沉积,大致相当于欧洲中泥盆统吉维特阶。
Sycidium fossils have been discovered in the Lower Permian defined by predecessors. The authors discuss the age of the horizon containing the fossils and consider that the Yezhutang Formation containing the Sycidium haikouense-S. lagenarium assemblage was deposited in the Dongganlingian Stage, broadly equivalent to the Givetian Stage(Middle Devonian) of Europe.
