Revue de Micropaléontologie, 2017Abstract The identity of presumed Terreneuvian (Stage 1, Fortunian) to Botoman (Series 2, Stage 3) radiolarians is discussed. The presence of radiolarians in the Lower Cambrian Hetang and Kuanchuanpu formations and the material from Jiuqunao, Hubei Province, China has to be regarded as a contamination with younger material.
