The Permian palynological Lueckisporites-Weylandites Biozone in the San Rafael Block and its correlation in Western Gondwana
(Pergamon-Elsevier Science Ltd, 2017-07)
A palynological study of the Yacimiento Los Reyunos Formation (San Rafael Block) Argentina was carried out in order to correlate the palynological data with other Permian assemblages and biozones from South America. The ...
Cave surface pollen and the palynological potential of karstic cave sediments in palaeoecology
(Elsevier Science, 2001-11-21)
Palynological results are presented of surface cave sediments from six caves of southeastern Spain, which differ in location, morphology, size, orientation and number of entrances. The results address several issues of ...
Palynological analysis of Lama guanicoe modern feces and its importance for the study of coprolites from Patagonia, Argentina
(Elsevier Science, 2012-09)
The aim of the present study was to develop a seasonality palynological model from modern feces of Lama guanicoe for the interpretation of pollen found in coprolites. For this purpose, fecal samples of L. guanicoe were ...
