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.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/SerrodiscusMarianianCambrian Series 2-Stage 4Sierra de Aracena y Picos de Aroche Natural ParkOssa-Morena zonejournal article10.21695/cterraproc.v1i0.394open access2506 Geología
