This is due to the mineralized skeleton that these organisms present and the existence of some post-mortem processes that allowed this type of conservation.spajournal articlehttp://www.sociedadgeologica.es/publicaciones_geotemas.htmlopen access56PaleozoicMacizo HespéricoSpainEchinodermsExceptional conservationPaleontología2416 Paleontología
