一、前言珠穆朗玛峰地区的孢子化石标本,系林宝玉同志于1981年采自西藏聂拉木县江东区亚里村中上泥盆统波曲群上部的绿色砂质页岩中。长期以来,由于缺乏古生物依据,对这套地层的时代难于确定。此次在砂质页岩中所获得的极其丰富的微体化石——孢子(共有44个属,103种,其中12个新种,16个新联合种),疑源类(Acritarchs,4个属,5个种,其中1 个新种),虫牙(Scolecodonts,3个属,3个种),不仅确定了波曲群的地质时代,为探讨珠
I. INTRODUCTION Species of spore fossils in Mount Everest are collected from green sandy shale in 1981 in the upper part of the Upper Devonian Bourd Group in Yali Village, Jiangdong District, Tibet, China. For a long time, due to the lack of palaeontology, the era of this formation is difficult to determine. The extremely rich microfossils - spores (44 genera, 103 species, 12 new species and 16 new ones) obtained in sandy shales, Acritarchs (4 5 species and 1 new species), Scolecodonts (3 genera and 3 species), not only confirmed the geologic age of the Burgas group,
