本文所记述的鱼类化石,是笔者近年来在伏牛山煤矿井下地质调查时,在晚二迭世龙潭组下部不含煤段(长石石英砂岩以下60～100米)底部的灰黑色、含钙质泥页岩中发现的。该层厚约35米,可明显地分为上、下两部,间夹厚约0～20厘米紫灰色或暗灰色透镜状钙质粉砂岩结核。上部:微细层理发育,除见有少量个体较大的鱼类化石(一般长约12～25厘米,最长达35厘米左右)外,尚伴有微小瓣鳃类化石(壳径约1毫米);下部:
Fish fossils described in this article, is the author in recent years when the Funiu Mountain coal mine geological survey, the bottom of the Late Permian Longtan Group non-coal-bearing section (feldspar quartz sand below 60 to 100 meters) at the bottom of the gray-black, containing Found in calcareous shale. The layer thickness of about 35 meters, can be clearly divided into the upper and lower two, between the thickness of about 0 ~ 20 cm purple gray or dark gray lenticular calcareous siltstone. Upper: fine stratigraphic development, in addition to see a small number of individual larger fish fossils (usually about 12 to 25 cm long, up to 35 cm), is still accompanied by small flap gill fossils (shell diameter of about 1 mm ); Lower part:
