本文首次描述了泰国南部通松和通瓦地区通松群中、下奥陶世牙形刺。这些牙形石可分为A、B和C三个动物群，分别为中-晚阿雷尼世、中阿雷尼世-达里维利世或卡拉多世、晚阿雷尼世-早卡拉多世。动物群A类似于澳大利亚、中国南方、阿根廷前科迪勒拉和北美的动物群。系统研究了12属15种植物。
ABSTRACT Lower and Middle Ordovician conodonts from the Thung Song Group, in the Thung Song and Thung Wa areas of southern peninsular Thailand, are described and illustrated here for the first time. These conodonts are divided into faunas A, B, and C, which are middle to late Arenigian, middle Arenigian to Darriwilian or Caradocian, and late Arenigian to early Caradocian, respectively. Fauna A resembles faunas in Australia, South China, the Argentine Precordillera, and North America. Fifteen species belonging to twelve genera were studied systematically.
