该文研究了青海乌兰地区晚石炭世至早二叠世的■类动物群,文中共描述了14属 79种,其中包括13新种及新亚种.作者根据■类化石在该区地层中垂直分布特征,将扎布萨尕秀组分为二■带及三亚带:上部 Sphaeroschwagerina 带,又可划分为,Robustoschwagerina qinghai- ana 亚带、Eoparafusulina 亚带及 Sphaeroschwagerina moelleri 亚带;下部 Triticites 带。亦将扎布萨尕秀组划分为三段,并对该区石炭、二叠系界线进行了讨论。
In this paper, the authors studied the fauna from the Late Carboniferous to the Early Permian in the Wulan area of Qinghai Province, and described 79 species of 14 genera, including 13 new species and new subspecies. In the vertical distribution, the Zhabusa Gaxiu group is divided into two groups: the second and the third sub-belts: the upper Sphaeroschwagerina belt, which can be divided into the Robustoschwagerina qinghai-ana belt, the Eoparafusulina sub-belt and the Sphaeroschwagerina moelleri belt, and the lower Triticites belt. The Zhabu-Sa-Ga-Xiu Formation is also divided into three sections, and the boundaries of Carboniferous and Permian in this area are discussed.
