This paper presents, for the first time, a complete list of Paleozoic radiolarian species (mainly Polycystina) described between 1880 and early 2016. It records 2323 names of taxa described originally as new species or subspecies that have been assigned to radiolarians. This list attempts to only provide an objective record without revision of taxonomic status, and thus includes invalid taxa, junior objective or subjective synonyms, nomina dubia and nomina nuda.
