| Sumario: | PALYNOLOGY OF THE BAJO DE VÉLIZ FORMATION (LOWER PERMIAN), SAN LUIS, ARGENTINA: SYSTEMATIC REVISION AND BIOSTRATIGRAPHIC CONSIDERATIONS. The original palynological samples studied by Menéndez from the Bajo de Véliz Formation (San Luis, Argentina), were revised. This stratigraphic unit has yielded one of the few Permian palynological associations recorded from the Paganzo Basin. Some species, such as: Latusipollenites? quadrisaccatus Marques-Toigo, Hamiapollenites fusiformis Marques-Toigo, Protohaploxypinus limpidus (Balme and Hennelly) Hart, Marsupipollenites striatus (Balme and Hennelly) Foster, and Vittatina subsaccata Samoilovich, were identified in the assemblage for the first time. The occurrence of Barakarites rotatus (Balme and Hennelly) Bharadwaj and Tiwari, Apiculatisporis cornutus (Balme and Hennelly) Høeg and Bose, Fusacolpites fusus Bose and Kar, Protohaploxypinus amplus (Balme and Hennelly) Hart, Verrucosisporites patelliformis (Menéndez) nov. comb., and Granulatisporites sp. cf. G. trisinus Balme and Hennelly, is confirmed. The presence of these species supports the inclusion of this palynological association in the Early Permian Argentinian Fusacolpites fusus-Vittatina subsaccata Biozone. |
