Abstract—

A new conodont species Icriodus olgaborisovnae sp. nov. is described from the Upper Eifelian Mosolovian Regional Stage of the Voronezh Anteclise on the basis of material from four boreholes. Previously, similar forms were identified as I. arkonensis Stauffer, 1938; however, the studies showed that the true I. arkonensis occurs in later rocks, in the Vorobyevian Regional Stage of the Givetian Stage of the Middle Devonian.

摘要-

牙形石新种Icriodus olgaborisovnae sp。十一月 根据四个钻孔的材料，从沃罗涅日前缘的上艾菲利亚摩索洛夫地区阶段描述。以前，类似的形式被确定为I. arkonensis Stauffer，1938；然而，研究表明，真正的I. arkonensis出现在较晚的岩石中，即中泥盆世吉维蒂亚阶段的沃罗比耶地区阶段。
