Radiolaria - Entactinaria - Entactiniidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|Y. Wang et al. 2003||Spherical radiolarian with two concentric shells. Relatively thick cortical shell with small pores. Inner medullary shell small and coarsely porous. Two very large, long, robust, strongly grooved, polar main spines. The width of the base of the two main spines is approximately one radius of the outer shell or greater. Four other small, commonly rodded, main spines may be present on a plane perpendicular to the two major heavy three bladed spines.|
