Nisusia Walcott, 1905 是角足亚门库托金科腕足动物的一个早期属。尼苏西亚起源于寒武纪 2，并在寒武纪 3 晚期灭绝，存在的地质时间相对较短，是形态进化缓慢的腕足动物属。本文详细介绍了中寒武纪凯里 Konservat-Lagerstätte 的腕足动物 Nisusia。就丰度而言，Nisusia 是凯里生物群中最重要的腕足动物之一。描述了贵州省东部寒武纪2-3系凯里组的两种尼苏虫：Nisusia granosa和Nisusia guizhouensis n.。 sp。这项研究将为尼苏西亚物种的形态变异提供有价值的见解，并提供有关凯里生物群中腕足动物群落组成的新细节。
Nisusia Walcott, 1905 is an early genus of kutorginid brachiopod of the Subphylum Rhynchonelliformea. Originating in the Cambrian Series 2.and becoming extinct in the late Cambrian Series 3, Nisusia existed for a relatively short period of geologic time, and is a brachiopod genus that.exhibited a slow rate of morphological evolution. This paper details the brachiopod Nisusia from the middle Cambrian Kaili Konservat-Lagerstätte..Nisusia, in terms of abundance, is one of the most important brachiopods from the Kaili Biota. Two Nisusia species from the Kaili Formation of the.Cambrian Series 2–3 in the eastern part of Guizhou Province are described, Nisusia granosa and Nisusia guizhouensis n. sp. This study will give.valuable insights into the morphological variability of Nisusia species, and provides new details on the composition of the brachiopod community.in the Kaili Biota.
