First fossil wood from the northern Pampa (Upper pleistocene), Santa Fe province, Argentina
(Asociación Paleontológica Argentina, 2019-08)
Paleobotany records from the Northern Pampa are very scarce and poorly known. 17 Only a palynological study in Paraná Formation (Upper Miocene) was previously done 18 (Anzótegui and Garralla, 1982, 1986). In this work, a ...
Late Pleistocene owls (Aves, Strigiformes) from Ecuador, with the description of a new species
(Springer, 2020-07)
The fossil record of owls of the families Strigidae and Tytonidae in South America is poor. The aim of the present contribution is to report for the first time fossil Strigiformes from Riobamba Canton, at Chimborazo province, ...
A new genus of oryzomyine rodent (Cricetidae: Sigmodontinae) from the pleistocene of Argentina
(Oxford University Press, 2008-10)
Based on a right maxillary with 1st molar recovered in Pleistocene (Ensenadan) deposits from south-central Buenos Aires Province, Argentina, a new genus and species of Oryzomyini (Rodentia, Cricetidae) is named and described. ...
Neosclerocalyptus Paula Couto (Xenarthra, Glyptodontidae) in the late Pliocene-earliest Pleistocene of the Pampean region (Argentina): Its contribution to the understanding of evolutionary history of Pleistocene glyptodonts
(Pergamon-Elsevier Science Ltd, 2020-07)
Glyptodontidae are a conspicuous lineage of Cingulata with a long evolutionary history (late Eocene to the late Pleistocene-Holocene). Quaternary forms are the best known, but in recent years the knowledge of Neogene taxa, ...
A new Pleistocene Ctenomys and divergence dating of the hyperdiverse South American rodent family Ctenomyidae
(Cambridge University Press, 2021-05)
The South American Ctenomys is the most speciose genus among both hystricomorphs and subterranean rodents of the world. Here, we present the most exhaustive phylogenies and timetree of living and extinct Ctenomys attempted ...
Campo Laborde: A Late Pleistocene giant ground sloth kill and butchering site in the Pampas
(American Association for the Advancement of Science, 2019-03-06)
The extinction of Pleistocene megafauna and the role played by humans have been subjects of constant debate in American archeology. Previous evidence from the Pampas region of Argentina suggested that this environment might ...
Changes in form and function of the caudal tubes in Panochthus (Xenarthra; Glyptodontidae) along the Pleistocene
(Taylor & Francis Ltd, 2021-12)
With eight species, Panochthus is one of the most abundant and diverse glyptodont genera during the Pleistocene of South America, as well as one of the largest glyptodonts. The relationship between the shape of the tube ...
Preliminary paleomagnetic results of a terminal pleistocene/holocene record from northeastern Buenos Aires province (Argentina)
(The University of Zagreb. Faculty of Science. Andrija Mohorovicic Geophysical Institute, 2006-12)
Paleomagnetic data from the Lomas del Mirador (34° 39.29’ S, 58° 32.17’ W) sedimentary section in northeastern Buenos Aires province (Argentina) comprises 149 oriented samples that record a significant but gentle gradual ...
Relationship between geohydrology and Upper Pleistocene-Holocene evolution of the eastern region of the Province of Buenos Aires, Argentina
(Pergamon-Elsevier Science Ltd, 2017-07)
The Upper Pleistocene-Holocene geological evolution, which is characterized by its landscape-forming energy and is related to geological and geomorphological complexity, has an impact on the groundwater dynamics of coastal ...
Paleoenvironmental reconstruction of central-western Argentina from analysis of Late-Pleistocene mammal droppings
(Academic Press Ltd - Elsevier Science Ltd, 2013-10)
Plant macrofossils studied in coprolites from small-sized, medium-sized and large mammals, dated by 14C to ca. 30.8-24 and 9kybp, allowed to record changes in local vegetation and its relation with geomorphological units. ...
