摘要：An Upper Paleozoic palynological assemblage from the Cerro Agua Negra Formation, Calingasta-Uspallata Basin, San Juan Province, Argentina, is described for the first time. The sporomorphs have been recovered at Las Leñas Creek from carbonaceous shales, which have been deposited in a subaerial environment corresponding to alluvial plain and interdistributary bays facies. The stratigraphic significance of the miospore assemblage is discussed.
