Abstract

Radiolaria have been recovered in acid residues from late Middle Cambrian strata in western Utah. Although the first Cambrian radiolaria were described by Nazarov (1973) from the Batenevskij Mountains of eastern Kazakhstan in the Soviet Union, radiolaria have not been reported from the Cambrian of North America. Except for the Kazakhstan specimens, the oldest known radiolaria are from the Lower Ordovician of western Spitsbergen (Fortey and Holdsworth, 1971). In North America only two accounts of Ordovician assemblages have been reported from southwestern Newfoundland and eastern Nevada (Bergström, 1974; Dunham and Murphy, 1976).
