摘要
系统描述了滇西南澜沧牡音河组晚二叠世最晚期和早、中三叠世放射虫化石,共计19属34种,并将其命名为牡音河动物群。该动物群明显地划分为4个组合,自下而上分别为Wangia组合(晚二叠世最晚期)、Shengia yini组合(早三叠世早期)、Pseudoeucyrits liui组合(早三叠世晚期)和Triassocampe deweveri组合(中三叠世早期)。
The Muyinhe Formation in Southwest Yunnan contains a diversified, fairly well-preserved Uppermost Permian to early Middle Triassic radiolarian fauna which includes 43 species belonging to 24 genera. The fauna is called the Muyinhe Fauna and divided into four assemblages : Wang ia assemblage (Uppermost Permian ), Sheng ia yini assemblage (early Early Triassie), Pseudoeucyrtis liui assemblage (late Early Triassic) and Triassocampe deteeveri assemblage (early Middle Triassic).
