Palynology of the La Veteada Formation (Permian) in the Sierra de Narváez, Catamarca Province, Argentina

Eighty-one species of spores and pollen grains together with algae and fungi remains were recovered from the shallow lacustrine successions of the La Veteada Formation at the Chaschuil river section (27°43'50.5″S- 68°01'7.0″W), Sierra de Narváez, Catamarca Province, Famatina Range, which a...
