Preferred term

RADIOLARIANS  

Definition

  • Radiolarians belong to the class Actinopoda, meaning "ray feet" which refers to the numerous slender, reinforced pseudopods that radiate from the body. Like foramniferans, the radiolarians are well represented in the fossil record, for they have ornate, silica-hardened parts that resist degradation. Radiolarian shells contribute to the formation of siliceous rocks such as chert. (en)
