过去,在我国有关晚二叠世珊瑚化石报道的不多,本文描述的新属镇安珊瑚(Zheng- anophyllum gen.nov.),系我们在1963年于陕西镇安西口一带测制晚二叠世地层剖面时采得,最近经笔者研究,现作一报道。镇安西口地区的上二叠统自下而上可以分为西口组、熨斗滩组和龙洞川组三部分。镇安珊瑚计有三个种,即:简单镇安珊瑚(新属、新种) Zhenganophyllum simplex (gen.et sp.nov.),灰质隔壁镇安珊瑚(新属、新种) Zhenganophyllum stereoseptatum(gen.et sp.nov.),弯曲状镇安珊瑚(新属、新种) Zhenganophyllum curvatum(gen.et sp.nov.)。它们分别产于前二个岩组内。
In the past, there were not many reports on the Late Permian coral fossils in China. The new genus An- lanophyllum gen.nov. Described in this paper was the result of the late Permian Sections of the earth acquired when the recent study by the author, is now a report. The Upper Permian in the west of Zhen’an West Area can be divided into three parts, namely, Xikou Formation, Flange Beach Formation and Longdongchuan Formation from the bottom up. There are three species of Zhenan coral: Zhenganophyllum simplex (gen.et sp.nov.), A simple coral reef (genus, new species) Zhenganophyllum stereoseptatum (gen. et sp.nov.), Curved Zhen’an coral (new genus, new species) Zhenganophyllum curvatum (gen.et sp.nov.). They were produced in the first two rock groups.
