Summary:Radiolarians, within the siliceous microfossils, constitute one of the most diverse protozoa groups. In general they are in compacted rocks: which makes it difficult to study. To the Northern Strip of the Heavy Crudes (FNCP, acronym in Spanish), the main sealing rocks are the sequences of the Paleocene-Eocene, in which calcareous microfossils are non-existent or very scarce, however, there are plenty of radiolaries. A total of 10 samples were analyzed in the Research Center Bio-stratigraphic Lab. These samples were taken from the Canasi pit 1x of the ore body bearing the same name at an interval of 1 780-2 020 m belonging to the High Vega Formation. The samples correspond to the siliceous-clayey facies in the core area and near the east. The methods implemented included the levigated, the section in suspension and the Scanning electron microscopy. This allowed determining 21 species of radiolaries within the genres of Entapium, Theocosphaera, Spongodiscus, Paracenodiscus, Buryella, Calocycloma, Lychnocanium, Theocotylissa, Dictyoprora, Podocyrtis, Phacodiscus, Conosphaera, Cenosphaera and Dictyomitra. It was possible to restrict the age of the sequence and report for the first time the existence of the Phacodiscus duplus species in Cuba.
