ESTUDIO PALEOBOTANICO DE LA FORMACION TASA CUNA, PERMICO INFERIOR DE LA PROVINCIA DE CORDOBA
AbstractIn this paper, the author develops a systematic study of a new palaeophytological Gondwanic association found in Córdoba, Argentine Republic. In a former study, the author proposed the creation of the Tasa Cuna Formation, for sediments carrying a Glossopteris taphoflora and fresh water Phyllopods, which crop out N. W. of Córdoba. In the same paper, and according to the palaeontological content, he assigned to this Formation a Lower Permian age, likely Sakmarian-Artinskyan, that is equivalenr to Lubeckense A" of the Argentine Flora-Age, elaborated by Archangelsky, S., (1971) for our state. The fossil plants, preserved like "cast" and impressions, are mainly represented by Glossopteridales, Cordaitales, Ginkgoales, Coniferales, Lycopsidae, Sphenopsidae and Filicopsidae. In order to increase the knowlegde of the Permian taphofloras, a new species is de termined, Glossopteris cordubensis, and the following are mentioned in Argentine for first time: Glossopteris spatbulato-cordata, Gangamopteris kasbmirensis, Rhipidopsis d. ginkgoides (accepted for the first time in our country), and Corynepteris (Alloiopteris) sp.
