摘要
描述采自广西靖西果乐剖面三都组一三叶虫新种Tamdaspis jingxiensis sp.nov.,根据该种三叶虫完整标本的背壳特征,认为Liushuicephalus Luo,1983是Tamdaspis Lisogor,1977的晚出异名。同时描述T.jingxiensis sp.nov.的个体发育过程和两块畸形标本,并认为该畸形是因被捕食者咬伤而形成的。
Tamdaspis jingxiensis sp. nov. is described from the Sandou Formation, Guole section, Jingxi County, southwestern Guangxi, China. The material includes a number of complete exoskeletons that added thoracic characters to the genus. Based on articulated materials of T. jingxiensis sp. nov., Liushuicephalus Luo, 1983 is regarded as a junior synonym of Tamdaspis.
The material of T. jingxiensis includes two malformed exoskeletons, and the malformation seems to be caused by predation.
