Small Antarctic Late Cretaceous chorate dinoflagellate cysts: biological and palaeoenvironmental affinities
(Taylor & Francis, 2014-09)
Small spiny marine palynomorphs have been the focus of recent palynological studies since their high proportions in Antarctic Late Cretaceous and Cenozoic assemblages were noted. These palynomorphs were assigned to the ...
Dinoflagellate cyst zonation for the middle to upper Eocene in the Austral Basin, southwestern Atlantic Ocean: Implications for regional and global correlation
(Cambridge University Press, 2017-09)
The well-exposed marine Eocene units from southwestern Patagonia, Argentina, contain useful information for reconstructing regional climate and oceanographic patterns in an area adjacent to the Drake Passage. The aim of ...
Similarities of the K/Pc dinoflagellate cyst associations between South Atlantic and Indian proto-oceans
(2016-12-01)
In this contribution we present the composition of the Late Cretaceous / Paleocene dinoflagellate cyst assemblages found in the Pelotas Basin, southern Brazil in order to provide a first paleobiogeographical comparison ...
Paleogene dinoflagellate cysts from the Punta Prat, Southern Chile
(Taylor & Francis, 2009-03)
Paleogene dinoflagellate cysts were recorded from the Chorrillo Chico and Agua Fresca formations at Punta Prat, southern Chile. Due to the presence of Palaeoperidinium pyrophorum, the Chorrillo Chico Formation is no younger ...
Influence of palaeoenvironmental factors on the encystment of Cretaceous dinoflagellate cysts (Ceratiaceae): a study from Godavari Graben, Southern India
(2017-10-02)
Muderongia staurota forms with long appendages at the distal end of the apical, lateral and antapical horns have been recovered from the Lower Cretaceous Gangapur Formation of Upper Gondwana sequence from the Chintalapudi ...
Calcareous dinoflagellate cysts from the Tithonian - Valanginian Vaca Muerta Formation in the southern Mendoza area of the Neuquén Basin, Argentina
(Elsevier, 2017-05)
The Late Jurassic – Early Cretaceous marine sediments of the Andean region show an excellent record of different calcareous microfossils, among which calcareous dinoflagellate cysts stand out. Detailed micropaleontological ...
Mid Jurassic (Late Callovian) dinoflagellate cysts from the Lotena Formation of the Neuquén Basin, Argentina and their palaeogeographical significance
(Elsevier Science, 2011-01)
The Lotena Formation from two localities, Picún Leufú and Portada Covunco, in the Neuquén Basin of west-central Argentina was studied palynologically. The material examined produced moderately diverse Late Callovian ...
Biostratigraphy based neogene dinoflagellate cysts in northeast of patagonia, Argentina
(Sociedade Brasileira de Paleontolog, 2016-05)
This paper presents the biostratigraphic results based on dinoflagellate cysts from two Neogene lithostratigraphic units cropping out in northeastern Patagonia. The Barranca Final Formation, located in the southwestern ...
Maastrichtian to Danian Atlantic transgression in the north of Patagonia: A dinoflagellate cyst approach
(Pergamon-Elsevier Science Ltd, 2019-06)
The late Maastrichtian to early Paleocene marine successions in northern Patagonia and neighboring southwestern Atlantic Ocean Basins provided a valuable organic-walled dinoflagellate cysts record. Assemblages around the ...
Middle Eocene Dinoflagellate cysts from Santa Cruz Providence, Argentina: Biostratigraphy and Paleoenvironment
(Elsevier, 2014-09)
The upper member of the Río Turbio Formation is a well-exposed marine Eocene unit at high latitudes in Patagonia, Argentina. It holds important information helpful to reconstruct regional climate and oceanographic patterns ...
