放射虫是早古生代海洋浮游生物领域的重要组成部分，但它们的起源和进化过程一直是个谜。放射虫的祖先代表被认为属于Archaeospicularia目，其毫无疑问的化石记录可以追溯到中寒武纪。我们在这里报道？湖北延家河组Terreneuvian中的囊胚海绵虫和未命名的球形放射虫。囊虫海绵是一种神秘的硅质微化石属，与放射虫、鞘虫级海绵和不确定的原生生物有亲缘关系。新发现的未命名放射虫，在形态上具有格壳、球形、体积小等特点。我们的发现支持球形放射虫是一种古老的代表的观点，它的起源和多样化可能比一般认为的要早得多。关于最古老的放射虫属于始祖虫目的假设需要重新检验。
Radiolarians form an important part of the planktonic realm in the ocean of Early Paleozoic, but their origin and evolutionary processes has long been enigmatic. The ancestral representatives of radiolarians have been considered to belong to the order Archaeospicularia, whose unquestionable fossil records were dated back to the Middle Cambrian. Here we report ?Blastulospongiaand unnamed spherical radiolarians in the Terreneuvian from the Yanjiahe Formation in Hubei Province, South China.Blastulospongiais an enigmatic siliceous microfossil genus, with affinities proposed amongst the radiolarian, sphinctozoan-grade sponges and uncertain protists. As for the newly discovered unnamed radiolarians, morphologically they possess latticed shell, spherical shape and are all small in size. Our discoveries support the idea that spherical radiolarians is an ancient representative, whose origin and diversification was probably much earlier than generally accepted. The hypothesis that the oldest radiolarians belong to the order Archaeospicularia needs to be re-examined.
