Palynological analysis of extinct herbivore dung from Patagonia, Argentina
(Pergamon-Elsevier Science Ltd, 2015-05)
Dung pollen studies can contribute information to the paleodiet and paleoenvironmental knowledge during the Pleistocene-Holocene transition. In this study, pollen analysis of extinct megaherbivore dung dated at 10,530 ± ...
Pollen morphology of selected species of Anacardiaceae and its taxonomic significance
(2021-01-01)
In the present work, the pollen morphology of 22 species of Anacardiaceae was analysed, occurring in the state of Bahia, Brazil. The palynological material was obtained from specimens deposited in herbaria. The pollen ...
Pollen morphology in selected species of Caricaceae with special reference to novel palynological characters
(Canadian Science Publishing, 2018-01)
The pollen grain morphology of Jacaratia corumbensis Kuntze, J. spinosa (Aubl.) A.DC., Vasconcellea quercifolia A. St.-Hil., and Carica papaya L. from Argentine samples were examined for the first time, using light and ...
Mid-latitude Paleogene dinoflagellate cysts from offshore Santa Catarina (Pelotas Basin, Southern Brazil): Taxonomy and biochronostratigraphy
(2021-10-01)
Palynological assemblages have been reported in pre-Quaternary deposits of the Pelotas Basin, except in the Santa Catarina Platform, where micropaleontological information is still restricted to calcareous microfossils. ...
Palynological, megafloral and mesofossil record from the Bajo Grande area (Anfiteatro de Ticó Formation, Baqueró Group, Upper Aptian), Patagonia, Argentina
(Elsevier Science, 2020-02)
The late Aptian flora of Baqueró is one of the best known and accurately dated Cretaceous plant associations from Gondwana, recognized for their well-preserved fossil remains. The Cerro Bayo (Bajo Grande area, Argentinean ...
Pollen morphology, ultrasculpture and ultrastructure of Poiretia Vent. (Leguminosae–Papilionoideae–Dalbergieae–Adesmia informal clade)
(2022-01-01)
Pollen morphology, ultrasculpture and ultrastructure were investigated for Poiretia in search of morphological characters of taxonomic importance using light microscopy as well as scanning and transmission electron microscopy. ...

(Taylor & Francis, 2008-12)
Palynomorph assemblages recovered from the Tupe Formation at La Herradura Creek, San Juan province, Argentina, are analysed. The middle section of the sequence includes a marine fossiliferous interval belonging to the ...
The Lopingian palynological Guttulapollenites hannonicus–Cladaitina veteadensis assemblage zone of Argentina, stratigraphical implications for Gondwana
(Pergamon-Elsevier Science Ltd, 2018-12)
The Lopingian Series, especially the Changhsingian Stage are here recognized for the first time in South America, in conjunction with the proposition of a new biostratigraphic unit for the uppermost Permian. The palynoflora ...
