Última Systematic palynological study of the Cortaderas Formation, (Mississippian) Río Blanco Basin, Argentina: Part Two Ameghiniana Pérez Loinaze,Valeria. Well preserved Mississippian palynological assemblages have been obtained from the Cortaderas Formation in the Río Blanco Basin, northwestern Argentina. In this second contribution, twenty- eight from a total of seventy-eight spore species are described. A new species of trilete spores is proposed: Densosporites scalabrinii sp. nov. Worldwide geographic and stratigraphic records of taxa are analysed. The Cortaderas Formation is dated as late Viséan in age based on the presence of species of potential stratigraphic relevance, such as Reticulatisporites magnidictyus Playford and Helby, Verrucosisporites quasigobbettii Playford and Helby and Rugospora australiensis (Playford and Helby) Jones and Truswell and the absence of pollen grains. The samples collected... Tipo: Info:eu-repo/semantics/article Palavras-chave: Argentina; Cortaderas Formation; Mississippian; Palynology; Systematics.

Well preserved Mississippian palynological assemblages have been obtained from the Cortaderas Formation in the Río Blanco Basin, northwestern Argentina. The geological setting and stratigraphic provenance of the samples is provided. In this first part, fifty-two species are described from a total of seventy-eight species of spores recognized. Five new species are proposed: Verrucosisporites incompositus sp. nov., Verrucosisporites perbrevis sp. nov., Anapiculatisporites exiguus sp. nov., Anapiculatisporites expolitus sp. nov. and Dibolisporites insolitus sp. nov. Previous worldwide geographic and stratigraphic records of taxa are detailed.

Ano: 2008 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0002-70142008000100003 Some trilete spores from Lower Carboniferous strata of the Rio Blanco Basin, western Argentina Ameghiniana Pérez Loinaze,Valeria. A new miospore genus Ductilispora is described to accommodate simple acamerate miospores, which have a distal ornament of folds like muri or thickenings. Five new species of trilete spores are defined: D. circularis sp. nov., D . longitudinalis sp. nov., D. corrugatus sp. nov., Verrucosisporites cortaderensis sp. nov., Dibolisporites malimanensis sp. nov. and Indotriradites variabilis sp. nov. The specimens have been recovered from the Malimán and the Cortaderas Formations (Early Carboniferous), in La Cortadera creek, San Juan province, Argentina.
