Abstract

Radiolaria are marine unicellular microorganisms characterized by skeletons of silica and the presence of cytoplasmic processes radiating from the cell body. Both the fine structure and architectural diversity of the skeletons are used as taxonomic criteria. They have been joined with Acantharia in the phylum Radiozoa Cavalier-Smith, 1987. Radiolaria are used as stratigraphy markers.
