The Rn potential of graptolite argillite and obolus phosphorite can be high, depending on the concentration of eU in rocks, reaching up to 1400 kBq/[m.

Obolus apollinis Eichwald, 1829 is the type species of the genus Obolus, the type genus of the family Obolidae, which is one of the most diverse early Palaeozoic linguloid families (Popov & Holmer 2003).
