surrounding a latticed shell. These three skeleton types can be mixed and matched to create seven skeleton categories in nassellarians. Even the simplest classifications of nassellarian morphology is complicated because of the wide variety of morphologies in the nassellarian order even when compared with their sister group, the spumellarians. The innate nature of the nassellarian geometry lends itself to diversity, which may be one of the factors leading to the rapid diversification of the nassellarians in comparison to the spumellarians during the

The most common group of radiolarians are the polycystine radiolarians, which are divided into two subgroups: the spumellarians and the nassellarians. Both spumellarians and nassellarians are common

The second skeleton type common in nassellarians is the aforementioned conical, porous skeleton. The third type is of a ring

Precambrian in age. The nassellarians appear in the fossil record much later than their other polycystine relatives, the spumellarians. spumellarians can be seen as far back as the Precambrian, whereas nassellarians do not
