Changing tectonic regimes in the central Costa Rica forearc between the Paleogene and the present: Insights from structural analysis and focal mechanisms
(Pergamon-Elsevier Science Ltd, 2021-01)
We discuss the Cenozoic history of the Central Costa Rica forearc, between 10° and 9°30′N, based on geological mapping, fault slip data and seismological records.The temporal variability in the regional stress-field suggests ...
Dental homologies and evolutionary transformations in Caviomorpha (Hystricognathi, Rodentia): new data from the Paleogene of Peruvian Amazonia
(Taylor & Francis Ltd, 2020-04)
Dental homologies and evolutionary transformations within caviomorph rodents have long been disputed. Here, we participate in these debates in providing new insights from the dental morphology of Paleogene caviomorphs from ...
Fossil woods from the Eocene-Oligocene (Río Turbio Formation) of southwestern Patagonia (Santa Cruz province, Argentina)
(Brill Academic Publishers, 2019-06)
Over 80 samples of fossil woods were collected from numerous outcrops of the Río Turbio Formation, southwestern Patagonia. Preservation of the woods is variable and only about half of these samples could be identified to ...
The first mammal assemblages from the Malargüe Group: Implications for the Paleogene evolution of the northern Neuquén Basin (Argentina)
(Pergamon-Elsevier Science Ltd, 2020-04)
We present two new Paleogene fossiliferous sites that provide the first mammal remains for the Malargüe Group in the Neuquén basin of southeastern Mendoza Province, Argentina. Identified taxa from Agua de Flores-Agua de ...
Fossil woods from the Eocene of Corcovado, Argentinean Patagonia: geological setting and conifer diversity
(International Association of Wood Anatomists, 2021-05)
Eocene paleofloras of Patagonia are diverse and increasingly known. A new assemblage of fossil wood has been recovered from Eocene sediments in Corcovado, western Argentinean Patagonia. The lithological succession (formerly ...
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 ...
