Comparison of the spores of the gender Cicatricosisporites R. Poto and Gell. 1933 Hungary and Colombia. Some problems concerning their stratigraphic significance

Abstract

The spores belonging to the morphologic genera Cicatricosisporites R. Poto and Gell. 1933 from Colombia and Hungry (specially the Dorog Basin) are discussed. Five colombian new species are described C. colombiensis, C. grandiosus, C. cirae, C. tabacensis and C. cundinamarcensis. Also it has been found the species C. susannae (Van der Hammen) is a synonym of C. dorogensis R. Poto and Gell., since they do not show a very importance difference in their characters. A detailed bibliography of the spores described under these genera with their stratigraphic significance is given. The range of these spores is Jurassic to lower Liassic and from actual report up to the Pliocene. Ideas are given about the probable botanic relationship of the spores of these genera.
