本文阐述了陕西焦坪矿区66号钻孔下侏罗统富县组“花斑泥岩”中发现的丝孢菌类分生孢子化石,并且鉴定出一个新属、一个新种。继而采用能谱仪及波谱仪对其成分作了定性分析,讨论了它与“花斑泥岩” 沉积环境之间的关系。作者认为丝孢菌类出现的时代应从白垩纪提前到早侏罗世。
In this paper, we describe the hyphomycete conidia fossils found in the “Porphyry Mudstone” of the Lower Jurassic Fuxian Formation in No. 66 Drilling Bureau of Jiao Ping, Shaanxi Province, and have identified a new genus and a new species. Then its composition was qualitatively analyzed by energy dispersive spectrometer and spectrometer, and its relationship with the depositional environment of “flowerpot mudstone” was discussed. The author believes that the occurrence of hyphomycetes should occur from the Cretaceous to the Early Jurassic.
