ResumoThis paper presents the first record of palynomorphs (acritarchs) from the Horqueta Formation, Bloque de San Rafael, Mendoza Province, Argentina. The stratigraphical range of identified species indicates a Silurian age to the studied palynoflora. Palaeontological data suggest the existence of an eventual graded transition from metamorphic into sedimentary rocks in the ex La Horqueta Serie from Ordovician or pre-Ordovician times ro the Devonian.
