摘要
通过研究福建省建阳县虞墩剖面所采集的腕足动物化石,共获6属5种,2个未定种,其中Paracrurithyris pygmaea,Tethyochonetes quadrata和Acosarina minuta在虞墩剖面为首次报道。综合化石时代分布和区域对比,将该动物群的时代确定为晚二叠世长兴期,含该动物群的地层为大隆组,而非文笔山组或泉上组。通过对该腕足动物群的古生态分析,并结合该套地层的沉积特征,判断沉积环境为温暖条件下的浅海相。
Based on studying the brachiopod fossils collected from Yudun profile in Jianyang County, Fujian Province, the authors ob-tained five species belonging to six genera. Among them, two indeterminate species and three species （ Paracrurithyris pygmaea, Tethy-ochonetes quadrata and Acosarina minuta） were discovered on Yudun profile for the first time. According to comprehensive fossil age distribution and regional correlation, this fauna was identified as belonging to the Late Permian Changhsingian period. The strata containing this fauna should be the Talung Formation instead of Wenbishan Formation or Quanshang Formation as previously consid-ered. Based on the paleoecology of the brachiopod fauna and the sedimentary characteristics of the strata, the authors hold that the strata were deposited in a warm and neritic environment.
