本文描述的新属镇安珊瑚(Zhenganophyllum),系我们在1963年于陕西镇安西口一带测制晚二迭世地层剖面时采得。镇安西口地区的上二迭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:Zhenganophyllum simplex,Zhenganophyllum stercoseptatum,Zhenganophyllum curvatum,它们分别产于前二个岩组内。
The new genus Zhenganophyllum, described in this paper, was obtained from our survey of the Late Permian stratigraphic profile in 1963 in the west of Zhen’an, Shaanxi. The Upper Erdian area in the west of Zhen’an West Area can be divided into three parts: the West Exit Formation, the Flanking Formation and the Longdongchuan Formation from bottom to top. There are three species of Zhenan coral, namely: Zhenganophyllum simplex, Zhenganophyllum stercoseptatum, Zhenganophyllum curvatum, which are respectively produced in the first two rock groups.
