报道了河南省西峡县湾潭地区二郎坪群火神庙组硅质岩夹层中的牙形石类Ａｃｏｄｕｓｏｎｅｏｔｅｎｓｉｓ及放射虫类ＥｎｔａｃｔｉｎｉａｃｏｍｐｌａｌＩａｔａ，其时代应属早、中奥陶世；与其相邻的大庙组泥质板岩中发现的螺旋管状藻类化石及其管状微化石的组合面貌可与早寒武世小壳动物群对比。这些化石的发现为二郎坪群的时代归属提供了较为可信的证据。
This paper reports the conodonts Acodusoneotensis and Entactiniacomplal Iata from the Silurian intercalation in the volcanic temple of Erlangping Group in the Bay Area, Xixia County, Henan Province. The epoch should belong to the Early and Middle Ordovician. The assemblage of spiral-shaped algae fossils and their tubular microfossils found in the argillaceous slate in the Miao Formation can be compared with that of the Early Cambrian crustaceans. The discovery of these fossils provides more credible evidence for the era of Erlangping Group.
