A Paleogeographic Overview of Tropical Fossil Sloths: Towards an Understanding of the Origin of Extant Suspensory Sloths?
(Springer, 2017-03)
Modern sloths are among the more characteristic mammals of South and Central American faunas. Recent discovery in four Paleogene, 22 Neogene, and dozens of Pleistocene fossiliferous localities in the tropics has revealed ...
Fossil pollen indicates an explosive radiation of basal Asteracean lineages and allied families during Oligocene and Miocene times in the Southern Hemisphere
(Elsevier Science, 2010-05)
Much of our knowledge of the past distribution and radiation of Asteraceae and allied families depends on the fossil pollen record. In recent years, new discoveries are coming to light from southern Africa, Australia, New ...
Updated synthesis of South American Mesotheriidae (Notoungulata) with emphasis on west-central Argentina
(Muséum d'histoire naturelle de la Ville de Genève, 2018-12)
Doctor Claude Guérin dedicated many years of his research to fossil rhinoceroses, but also to some of the interesting mammals that evolved in South America. This is why I contribute to this volume in his memory with a ...
Long-term landscape evolution and post-rift reactivation in the southeastern Brazilian passive continental margin: Taubat, basin
(Springer, 2014-03-01)
Zircon (ZFT) and apatite (AFT) fission-track low-temperature thermochronology was applied at the Brazilian passive continental margin in order to understand and reconstruct the post-rift evolution since the breakup of ...
New age constraints for the Cenozoic marine transgressions of northwestern Patagonia, Argentina (41°-43° S): Paleogeographic andtectonic implications
(Pergamon-Elsevier Science Ltd, 2014-01)
In this contribution we address the current controversial issues related to the age, correlation, tectonic setting and paleogeographic links of the Cenozoic fossiliferous marine strata that crop out in the eastern sector ...
Paleoclimate estimates for the Paleogene Neogene in southern South America using fossil leaves as proxiesEstimations du paléoclimat pour le Paléogène-Néogène dans le sud de l’Amérique du Sud en utilisant des feuilles fossiles comme indicateurs
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2021-01)
It is widely recognized that fossil leaves are good proxies for paleoclimate estimates, and leaf physiognomy analysis is a traditional technique used to make climate estimates. There are only a few paleoclimate reconstructions ...
Crustal structure of the high Andes in the North Pampean flat slab segment from magnetic and gravity data
(Pergamon-Elsevier Science Ltd, 2017-01)
The Main Andes at the northern Chilean-Pampean flat slab segment were formed by the inversion of late Oligocene to early Miocene extensional depocenters in Neogene times. Their structure, size and depth are loosely constrained ...
Paleogene and Neogene magmatism in the Valle del Cura region: New perspective on the evolution of the Pampean flat slab, San Juan province, Argentina
(Pergamon-Elsevier Science Ltd, 2007-09)
El Valle del Cura está geológicamente caracterizado por una espesa secuencia volcánica y volcániclástica que registra la evolución del magmatismo terciario de arco y retroarco de la Cordillera Frontal de Argentina sobre ...

Palynotaxonomy of the cretaceos to neogene section of the pelotas brasin, brasil: Dinoflagellate cysts of ptychodiscales and gonyaulacales ordersPalinotaxonomia da seção cretácea a neogena da bacia de pelotas, brasil: Cistos de dinoflagelados das ordens ptychodiscales e gonyaulacales
(2018-01-01)
Dinoflagellate cysts are commonly used to obtain the relative ages, correlations and paleoenvironmental interpretations of the Cretaceous and Paleogenic sections of the Brazilian continental margin. However, the ...
