Nowadays, the genus Serrodiscus is noted as the first trilobite genus with global distribution in the early Cambrian oceanic platform environments, so its FAD is currently considered for the definition of the base of Cambrian Stage 4. Therefore, its presence in the Marianian rocks from northern Huelva could strengthen the correlation with another early Cambrian localities worldwide.}, organization = {We want to thank the Council of Environment and Territorial Planning from the Junta de Andalucía and the Directorate of Sierra de Aracena y Picos de Aroche Natural Park for providing permission to work into the park.
