海南岛的Cystophrentis-Pseudouralinia间隔带及三叶虫化石
Science Technology and Engineering(2009)
Abstract
根据Siphonodella levis(Ni) Polygnathus cf..inornatus E.R.Branson等牙形刺化石,海南岛白沙县金波老村附近南好组第二段中上部确定为下石炭统杜内早期,与Cystophrentis—Pseudourlinia间隔带底部层位相当。共同产出的Weberiphillipsia cf.linguiformis Yuan & Li,Weberiphillipsia sp.,Linguaphillipsia sp.,Hunanoproetus sp.,Austrulosutura sp.,Conophillipsia sp.等系海南岛首次发现的早石炭世三叶虫化石。它与澳大利亚新南威尔士同期三叶虫很相似,可能属同一古生物地理区。
