(Universidade de São Paulo, Instituto de Geociências, 2010)
Development of an incipient Paleogene topography between the present-day Eastern Andean Plateau (Puna) and the Eastern Cordillera, southern Central Andes, NW Argentina
(Wiley Blackwell Publishing, Inc, 2020-09-25)
The structural and topographic evolution of orogenic plateaus is an important research topic because of its impact on atmospheric circulation patterns, the amount and distribution of rainfall, and resulting changes in ...
Extensional tectonics during Late Cretaceous evolution of the Southern Central Andes: Evidence from the Chilean main range at ~35°S
(Elsevier Science, 2018-10)
The study of Late Cretaceous-earliest Paleogene series in the Chilean Andes at ~35°S provides new constraints on the coeval evolution of the area and the Southern Central Andes. These correspond to the continental series ...
Postcranial remains of basal typotherian notoungulates from the eocene of Northwestern Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2020-03)
Notoungulates represent the most taxonomically diverse and temporally and geographically widespread group among South American native ungulates. Here, we analyze anatomical and systematic aspects of proximal tarsal bones ...
Incisor Enamel Microstructure of Paleogene Caviomorph Rodents from Contamana and Shapaja (Peruvian Amazonia)
(Springer, 2018-02)
We investigate the enamel microstructure of 37 isolated rodent incisors from several late middle Eocene and late Oligocene localities of Contamana (Loreto Department, Peruvian Amazonia), and from the early Oligocene TAR-01 ...
Palynology and palaeocommunities of the Paleogene of Argentina
(Sociedade Brasileira de Paleontologia, 2006-12)
Two major paleophytogeoprovinces based on the palynological record at the genus or species level and at the palaeocommunity level are recognized for the Danian of Argentina. The presence of Verrustephanoporites simplex ...
New specimen of Pucatherium parvum (Xenarthra, Dasypodidae), a singular dasypodid of the Paleogene (Eocene) of northwest Argentina: importance in the early evolution of armadillos
(Society of Vertebrate Paleontology, 2019-07)
A new specimen of Pucatherium parvum from the lower levels of the Upper Lumbrera Formation of Salta Province is reported. An almost complete dorsal carapace and several postcranial remains were preserved, providing important ...
Palynological record of the Paleogene Río Leona Formation (southernmost South America): Stratigraphical and paleoenvironmental implications
(Elsevier Science, 2009-04)
Terrestrial palynomorph assemblages have been recovered from the Río Leona Formation, southwestern Santa Cruz Province, southern South America. Organic debris (spores, pollen grains, fresh water algae, plant tissues and ...
Paleoecology and paleoenvironments of Podocarp trees in the Ameghino Petrified forest (Golfo San Jorge Basin, Patagonia, Argentina): Constraints for early Paleogene paleoclimate
(Universidad de Barcelona. Facultat de Ciències de la Terra, 2011-03)
During the Early Paleocene (Danian), Central Patagonia had a warm-temperate climate and was dominated by evergreen coniferous forests. Abundant permineralized conifer woods along with some dicot and palm leaf compressions ...
Mid-latitude Paleogene dinoflagellate cysts from offshore Santa Catarina (Pelotas Basin, Southern Brazil): Taxonomy and biochronostratigraphy
(Elsevier, 2021-10-06)
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. ...
