Radiolarians species, members of the subclass Radiolaria, are single-celled eukaryotes commonly found in marine environments (with some being colonial). Read on.. Here we provide a comprehensive morpho-molecular framework to assess the extant diversity, biogeography, and evolutionary history of Radiolaria. Our analyses reveal that half of radiolarian diversity is morphologically undescribed, with a large part forming three hyper-diverse environmental clades, named Rad-A, Rad-B, and Rad-C.

Like diatoms, radiolarians come in many shapes Also like diatoms, radiolarian shells are usually made of silicate acantharian radiolarians have shells made from strontium sulfate crystals Slideshow of radiolarian diversity [15] Cutaway schematic diagram of a spherical radiolarian shell Cladococcus abietinus. 7. Geological Range The radiolarians range from the Cambrian period, but the skeleton-less forms may have evolved in the latest Precambrian. Their abundance in many rocks, their long geologic history, and their diversity through time make them important sources of information on the geologic age and structure of many deposits. 8.
