Resumen:
The Carrizal Formation, exposed in the Marayes-El Carrizal Basin (western Argentina), hasbeen the focus of palaeobotanical studies since the late 1800s. The recent finding of wellpreservedpalynological assemblages provides the first detailed studies about its palynofloras. In this paper, the sixty-three taxa identified in the unit are illustrated anddiscussed, as well as, considered their stratigraphic distribution in equivalent palynological assemblages of Argentina. Some spore species are revised: Uvaesporites hammenii (Herbst) comb. nov., Retusotriletes wielandii (Jain) comb. nov. and Lundbladispora stellae (Herbst) comb. nov. The recognition of Cadargasporites baculatus de Jersey et al., Craterisporites rotundus de Jersey, Enzonalasporites vigens Leschik, Leptolepiditesargenteaeformis (Bolkhovitina) Morbey, Protodiploxypinus americus Dunay & Fisher andRugulatisporites permixtus Playford, among others, appears to be useful for local andintercontinental correlations. A Carnian age is proposed for the palynofloras.
