摘要
该文记述了广西隆林祥播中二叠统茅口阶下部(Cancellina带)的Armenina动物群,计11种,其中6新种,1个未定种。该动物群产于海相亮晶生物屑灰岩之中,属浅海生物滩相沉积环境。Armenina由Misellina演化而来,继之向Verbeekina及Paraverbeekina演进,是该演化系列中的关键环节,与其上或下亲缘属有明显差异,应视作一个独立的属,归于Verbeekinine亚科。Armenina属大多数种产于茅口阶Cancellina带,少数高级种延续至茅口阶Neoschwagerina带。文中同时论述了Armenina动物群的一般特征及演化趋向。
The fusulinids described in this paper were collected from the lower Maokou stage (Cancellinazone) of the Middle Permian at Xiangbo, Longlin, Guangxi. They abundantly occur within the light-coloured carbonate rocks of organic clastic shoal facies where most species of Armenina are wellrepresented. In the evolution of fusulinids,the genus Armenina is an intermediate link between Misellina andVerbeekina. Armenina is here considered as a genus belonging to the subfamily Verbeekininae. Heredescribed are 17 species, including 10 new species and 3 unnamed species; the general characteristicsand evolutionary trend of the Armenina fauna is discussed.
