New radiometric 40Ar–39Ar dates and faunistic analyses refine evolutionary dynamics of Neogene vertebrate assemblages in southern South America
(Nature, 2021-12)
The vertebrate fossil record of the Pampean Region of Argentina occupies an important place in South American vertebrate paleontology. An abundance of localities has long been the main basis for constructing the ...
Systematics, phylogeny and evolutionary pattern of the hystricognath rodent Eumysops (Echimyidae) from the Plio-Pleistocene of southern South America
(Taylor & Francis, 2015-11)
†Eumysops is a peculiar representative of the currently tropical family Echimyidae, which evolved in increasingly dry and cold Plio–Pleistocene environments of southern South America. The results of a systematic and ...
Temporal and altitudinal variations in benthic macroinvertebrate assemblages in an Andean river basin of Argentina
(Istituto per lo studio degli Ecosistemi, 2014-02)
Environmental variables and benthic macroinvertebrate assemblages were spatially and seasonally examined over two consecutive years (2000-2002) along a glacier and snowmelt river in the central-west of Argentina where lies ...
New hadrosaurid (Dinosauria: Ornithopoda) fossils from the uppermost Cretaceous of central Patagonia and the influence of paleoenvironment on South American hadrosaur distribution
(Pergamon-Elsevier Science Ltd, 2021-10)
We describe and incorporate fragmentary new cranial and postcranial materials of hadrosaurid ornithopods into the non-avian dinosaur assemblage of the Upper Cretaceous (Coniacian–Maastrichtian) Lago Colhué Huapi Formation ...
New well-preserved craniodental remains of Simomylodon uccasamamensis (Xenarthra: Mylodontidae) from the Pliocene of the Bolivian Altiplano: Phylogenetic, chronostratigraphic and palaeobiogeographical implications
(Wiley Blackwell Publishing, Inc, 2019-02)
Fossil remains of extinct terrestrial sloths have been discovered in numerous localities throughout the Americas, but knowledge of these animals remains poor in the tropical latitudes in comparison with the austral ones. ...
Foraminíferos planctônicos e bentônicos do intervalo aptianoalbiano do DSDP Site 364 (bacia de Kwanza): taxonomia, bioestratigrafia, paleoecologia e implicações paleoceanográficas
(Universidade do Vale do Rio dos Sinos, 2012-11-12)
This work presents a taxonomic, biostratigraphic and paleoecologic study on the planktic and benthic foraminiferal faunas recovered from the late Aptian-late Albian carbonatedominated succession of Deep Sea Drilling Project ...

A high-precision U–Pb zircon age constraints the timing of the faunistic and palynofloristic events of the Carnian Ischigualasto Formation, San Juan, Argentina
(Pergamon-Elsevier Science Ltd, 2021-11)
The Late Triassic represents records many of the most critical biotic crises in life-history (from Carnian to the end-Triassic extinction, ETE). Some hypotheses propose that these life changes were linked with shifts in ...
