Porto Primavera Ichnofossil Geosite, Brazil: Geoconservation Measures in a Protected Area

Porto Primavera geosite comprises aeolian sandstones with tetrapod trace fossil cropping out at the Hydroelectric Power Plant, São Paulo State, Brazil. The Upper Cretaceous Rio Paraná Formation, which contains these tracks, is composed of medium–fine quartzarenites well- sorted and supermature, typically large tabular/trough cross-bedding. They accumulated in complexes barchanoid dunes, moved by winds to south-west. association consists tracks theropod dinosaurs small mammals preserved concave epirelief. These rare records desert environments from Late Brazil indicate that even interior Caiuá was occupied organisms. study focused on characterization ichnofossils, assessing their susceptibility degradation natural anthropogenic processes, proposing measures manage geosite. Because risk high, it proposed prior removal slabs should be replaced synthetic resin replicas made using silicone rubber moulds. sense disconnection between objects geological context could addressed depositing near Museum Regional Memory. indicated as a new holostratotype Formation.
