Polycystine
The polycystines are a group of radiolarians. They include the vast majority of the fossil radiolaria, as their skeletons are abundant in marine sediments, making them one of the most common groups of microfossils. These skeletons are composed of opaline silica. In some it takes the form of relative... wikipedia.org

【地球生物全系列——从单细胞到人类】原生生物界—放射虫门 - 知乎
从宇宙诞生到人类文明 原生生物界—放射虫门 放射虫门（学名：Radiozoa）又名放线虫，为海中浮游生物，有如球形对称，带有硅壳，壳上有美丽的花纹。 身体内有膜质中央囊，囊面穿有许多小孔，将身体分为内外两部分，外部被胶状物质，多有液泡，内部有细胞核、液泡和赤、黄等色的油滴；通常均由身体中央射出针状骨棘，间或多数针状物相集成层或互相连络而成笼状，形状精细繁多；多以分裂法繁殖，也有以孢子繁殖的。 放射虫多产于热带海洋中，因为迅速的繁殖与过多的物种，是诊断化石的重要依据，可从寒武纪开始。 放射虫有很多针状伪足的支援，即所谓axopods，可承受放射虫的浮力。 1.分类 多孔虫纲（英语：Polycystine）（Polycystinea）

Nassellaria
The most common group of radiolarians are the polycystine radiolarians, which are divided into two subgroups: the spumellarians and the nassellarians. The nassellarians appear in the fossil record much later than their other polycystine relatives, the spumellarians. spumellarians can be seen as far back wikipedia.org

西菲律宾海硅藻席沉积中的多囊虫类放射虫记录及其环境意义
In order to understand the formation process of marine laminar sediments from multiple perspectives, this paper studied the changes of polycystine radiolarian assemblages and their environmental significance by using the XT47 core samples with laminar diatom mats collected in the western Philippine Sea. Results show that there were abundant ... www.earth-science.net
