Аннотация:This chapter is to be used as companion text with the companion chapter, an illustrated catalogue of Paleozoic radiolarian genera found in this volume, and serves the purpose of giving the reader explanation for any taxonomic operations undertaken during the course of constructing the catalogue. These operations refer to the status of the genera as valid, junior synonym, homonym, nomen nudum, nomen dubium, or not Radiolaria. We also include diagnoses and/or descriptions in the original language published, English translations where needed, and locality and age information for the type material.
