Palynology of the Jagüel Formation (Maastrichtian–Danian) in northwestern Río Negro, Neuquén Basin, Argentina: paleobiogeographic inferences
The palynology of the Jagüel Formation at Cerro Azul locality Río Negro province; in the Neuquén Basin, was studied. The distribution of palynomorphs (spores, pollen grains, chlorophytes, and miscellaneous forms) across the outcrops allowed the definition of three palynological associations: A1 (upp...

The palynology of the Jagüel Formation at Cerro Azul locality Río Negro province; in the Neuquén Basin, was studied.

The palynological results, together with micro- and invertebrate fossils found in this locality contributed to the paleoenvironmental reconstruction of this unit. A1 is deposited in mixed (coastal) to shallow marine environments with low energy associated to freshwater bodies. Whereas it is interpreted that A2 and A3 are deposited in coastal lagoons near shallow and internal platform marine environments. The largest number of palm pollen grains of Proxapertites and other angiosperms Retitrescolpites baculatus and Striatopollis for the Danian of Argentina has been registered here.
